Model Charts Model Programming, Flashing, and Cloning

Model Charts General Description

Programming, Flashing, and Cloning

Four model charts cover the three families of radios discussed in this publication:

Conventional Systems Radios, HT 1000 Conventional Systems Radios, JT 1000 and MT 2000 Private Systems Radios Shared Systems Radios

Each model chart lists the model number and its description, and the three main radio components: the transceiver board, the controller board, and the front cover. A single model may be built using alternate controller boards and alternate transceiver boards. The model charts will list all alternate controllers and all alternate transceivers for any one particular model. Other model components are referenced in electrical parts lists and exploded view parts lists located toward the rear of the manual.

To determine which controller and transceiver is in a radio, that radio must be opened and physically examined. Identification kit number labels are attached to the controller board and to the transceiver board.

All HT 1000, JT 1000, MT 2000, MTS 2000, and MTX Series Radios covered in this manual are clonable. The JT 1000 Model Radios are also front-panel programmable, and the MTS 2000 Series Radios are applies only to HT 1000 Model Radios.

“flashable.” The following cloning information

HT 1000 Model Radios:

VHF DN models cannot be cloned to AN, BN, or CN models. Any DN model can be cloned from like CN or DN models. Prior to cloning any AN or BN model into a like CN or DN

model, a code plug fix must be performed on the AN or BN model. Failure to do so could seriously degrade the scan and battery-saver capabilities of the CN or DN model radio. For code plug-fix information, order Service Repair Notice, SRN-1218. Note: Cloning any AN model into a like CN or DN model will remove the TEST MODE capability.

Performance Testing 3

General The HT 1000, JT 1000, MT 2000, MTS 2000, and MTX series radios

have been prepared to meet published specifications through their manufacturing process, with the use of laboratory-quality test equipment of highest accuracy. The recommended field service equipment approaches the accuracy of the manufacturing equipment with a few exceptions. Accuracy of the equipment must be maintained in compliance with the manufacturer’s recommended calibration schedule.

Setup Supply voltage can be connected from the battery eliminator. The

equipment required for alignment procedures is connected as shown in the Radio Alignment Test Setup diagram.

Initial equipment control settings should be as indicated in the following table, and should hold for all alignment procedures except as noted in Table 4.

NOTE: This note applies to software version R02.09

and earlier. If the radio is placed in TEST MODE

Page 30

with Option•Mate interface plug enabled through the HT 1000 RSS, TX and RX audio will be muted. Do not test Analog Voice Security (AVS) installed radios in the TEST MODE.

When the HT 1000/JT 1000 radio is operating in its normal environment, the radio's microcontroller controls the RF channel selection, transmitter key-up, and receiver muting. However, when the unit is on the bench for testing, alignment, or repair, it is removed from its normal environment. It cannot receive commands from its system and, therefore, the internal microcontroller will not key the transmitter nor unmute the receiver. This prevents the use of normal tune-up procedures. To solve this problem a special routine, called TEST MODE or “air test,” has been incorporated in the radio.

To enter test mode:

1. Turn the radio on.

2. Within ten seconds after the self test is complete, press the monitor button (side button 3, SB3) five times in succession. After the fifth press:

a. (HT 1000 radios), a tone is emitted to indicate that the rf test

mode has been entered.

b. (JT 1000 radios), the display will show the firmware version of

the microprocessor for two seconds, emit a tone, then display TEST MODE).

3. Each additional press of SB3 will advance to the next test channel. (refer to Table 6), and a corresponding set of tones will indicate the channel.

4. Pressing SB2 will scroll through and access test environments as shown in Table 5.

NOTE: Transmit into a load when keying a radio

under test.

To exit test mode, turn the radio off then back on.

To check the buttons and the switches, perform the following tests:

1. Turn radio on.

2. After the self test is complete, press the monitor button (side button 3, SB3) five times in succession, within 10 seconds. After the fifth press, a tone is emitted to indicate that the RF test mode has been entered.

3. Exit the RF test mode and enter the control head test mode by pressing and holding SB3 for more than three seconds. Upon entering the control head test mode, a tone is emitted and the green LED begins flashing. The green LED continues to flash until the control head test mode is exited.

NOTE: Return to the RF test mode by pressing and

holding SB3 for more than three seconds. Then re-enter the control head test mode by pressing and holding SB3 for more than three seconds.

4. Test each switch (toggle, rotary, or button-actuated) by changing the position of the switch. A tone is emitted to indicate a “good test” each time a switch position is changed.

NOTE: Pressing and releasing a button-actuated

switch are both considered switch-position changes.

NOTE: No tone when a switch position is changed

indicates a test failure. Test the on/off volume potentiometer/switch by rotating the potentiometer clockwise and counter

Page 32

clockwise. The loudness of tone beeps will increase and decrease accordingly.

NOTE: During test mode, the volume level is not

regulated to the same limits as during normal radio operation.

To exit test mode, turn the radio off then back on.

RF Test Mode, MT 2000, MTS 2000, and MTX Series Radios

When the MT 2000, MTS 2000, or MTX series radio is operating in its normal environment, the radio’s microcomputer controls the RF channel selection, transmitter key-up, and receiver muting. However, when the unit is on the bench for testing, alignment, or repair, it is removed from its normal environment. It cannot receive commands from its system and, therefore, the internal microcomputer will not key the transmitter nor unmute the receiver. This prevents the use of normal tune-up procedures. To solve this problem a special routine, called TEST MODE or “air test,” has been incorporated in the radio.

To enter test mode:

1. Turn the radio on.

2. After the self test is complete, press the monitor button (side button 3, SB3) five times in succession, within 10 seconds.

Error-Code

Displays 4

Power-up Display Codes

At power-up, the radio performs cursory tests to determine if its basic electronics and software are in working order. Problems detected during these tests are presented as error codes on the radio display. The presence of an error code should prompt the user that a problem exists and that a service technician should be contacted.

Figure 2 RSS Service Menu Layout

All service and tuning procedures are performed from the SERVICE menu, which is selected by pressing F2 from the MAIN MENU. Figure 2 illustrates how the RSS SERVICE screens are organized.

All SERVICE screens read and program the radio codeplug directly; you do NOT have to use the RSS GET/SAVE functions to use the SERVICE menus. You will be prompted at each screen to save changed values before exiting the screen. RSS references in this manual are to HT 1000 / JT 1000 RSS. Some slight differences may be noted it you are using the MTS/MTX RSS.

Test Mode Menu

MAEPF-22857-A

Do NOT switch radios in the middle of any SERVICE procedure. Always use the EXIT key to return to the MAIN menu screen before disconnecting the radio. Improper exits from the SERVICE screens may leave the radio in an improperly configured state and result in seriously degraded radio or system performance.

The radio contains internal test modes that can be accessed from the RSS. The test modes permit the service technician to easily select various frequency, modulation, and transmit power combinations to verify proper operation of the radio. The test modes can be used to check both transmit and receive operation. From the Service Menu press F6 to navigate to the TEST MODE screen.

The SERVICE screens introduce the concept of the “softpot”, an analog SOFTware controlled POTentiometer used for adjusting all transceiver alignment controls.

Page 41

Each SERVICE screen provides the capability to increase or decrease the ‘softpot’ value with the keyboard UP/DOWN arrow keys respectively. A graphical scale is displayed indicating the minimum, maximum, and proposed value of the softpot, as shown in Figure 3.

015

Min.

Value

Figure 3 Softpot Concept

Adjusting the softpot value sends information to the radio to increase (or decrease) a DC voltage in the corresponding circuit. For example, pressing the UP arrow key at the Reference Oscillator screen instructs the radio microprocessor to increases the voltage across a varactor in the reference oscillator to increase the frequency.

In ALL cases, the softpot value is just a relative number corresponding to a D/A (Digital-to-Analog) generated voltage in the radio. All standard measurement procedures and test equipment are similar to previous radios.

Perform the following procedures in the sequence indicated.

Reference Oscillator Alignment

Adjustment of the reference oscillator is critical for proper radio operation. Improper adjustment will not only result in poor operation, but also a misaligned radio that will interfere with other users operating on adjacent channels. For this reason, the reference oscillator should be checked every time the radio is serviced or once a year, whichever comes first. The frequency counter used for this procedure must have a stability of 0.1 ppm (or better).

1. From the SERVICE menu, press F2 to select TRANSMITTER alignment.

2. Press F2 again to select the REFERENCE OSCILLATOR softpot.

3. Press F6 to key the radio. The screen will indicate that the radio is transmitting.

4. Measure the transmit frequency on your service monitor.

Transmit Deviation Balance (Compensation)

Compensation alignment balances the modulation sensitivity of the VCO and reference modulation (synthesizer low frequency port) lines. The compensation algorithm is critical to the operation of signalling schemes that have very low frequency components (e.g. DPL) and could result in distorted waveforms if improperly adjusted.

NOTE: Disable all audio band filters on the service monitor.

VCO Crossover Frequency

NOTE: This procedure is only required after the field

repair of a VHF or UHF VCO.

In order for a phase-locked-loop to tune very wide bandwidths, both negative and positive control voltages (Vcntl) are required. This procedure sets the crossover frequency at which the negative Vcntl (or –Vee) switches from zero to negative.

Transceiver Board Identification

VHF Radios VHF transceiver board NUD7070 and NUD7085 (“C” and later) kits

include new VCO varactors, and are factory aligned with a new transmit VCO crossover frequency of 164.850MHz.

Since the transmit crossover frequency has changed, whenever transmit VCO crossover alignment (an RSS function) is performed, circuit board identification will be important. The “C” kits can be identified by the circuit board number 5511Y02 or 5511Y32 visible on side 2 of the board, located along the circuit board edge just next to crystal filter FL1. All future VHF transceiver boards will be in the “5511Y” series.

Anytime a controller board or transceiver board is replaced in a radio, it will be necessary to perform the RSS transmit VCO crossover alignment, and check the transmit VCO crossover frequency. The RSS s c r e e n f o r t h i s a l i g n m e n t w i l l s h o w a “ c u r r e n t v a l u e ” b o x with a frequency already assigned, placed inside the box. When performing transmit VCO crossover alignment, first check the transceiver circuit board number. In a VHF radio:

• If the board number is any “5511Y” series number, other than 5511Y01 or 5511Y31, the transmit VCO crossover frequency in the “current value” box should be 164.850MHz. If it is not, change it to 164.850MHz.

• If the board number is 5511Y01, 5511Y31 or any other number not in the 5511Y series, the transmit VCO crossover frequency in the “current value” box should be 161.50500MHz. If it is not, change it to 161.50500MHz.

Page 47

VCO varactors (CR201, 202, and 203) in “C” and later kits are not interchangeable with VCO varactors in earlier kits; Motorola parts and part numbers are different. When replacing a VCO varactor, Identify the transceiver board and order replacement parts from the applicable parts list.

UHF, 403-470MHz Radios UHF transceiver board (403 - 470MHz band split) NUE7231 and

NUE7240 (“C” and later) kits include new VCO varactors, and are factory aligned with a new transmit VCO crossover frequency of

449.500MHz.

Since the transmit crossover frequency has changed, whenever transmit VCO crossover alignment (an RSS function) is performed, UHF band split and circuit board identification will be important.

• UHF band split can positively be determined by checking the markings on the power amplifier shield. If the power amplifier shield marking is 25U04 or 85Y10, then the transceiver is a 403 470MHz band split. If the power amplifier shield marking is 25U05 or 85Y11, then the transceiver is a 450 - 520MHz band split.

• The “C” kits can be identified by the circuit board number 4221J07 or 4221J37 visible on side 2 of the board, located along the circuit board edge just next to crystal filter FL1. All future UHF transceiver boards will be in the “4221J” series.

Anytime a controller board or transceiver board is replaced in a radio, it will be necessary to perform the RSS transmit VCO crossover alignment, and check the transmit VCO crossover frequency. The RSS screen for this alignment will show a “current value” box with a frequency already assigned, placed inside the box. When performing transmit VCO crossover alignment, determine the UHF transceiver band split, and then check the transceiver circuit board number. In a UHF radio (403 - 470MHz range):

• If the board number is any “4221J” series number, other than 4221J01 thru 4221J06 or 4221J36, the transmit VCO crossover frequency in the “current value” box should be 449.500MHz. If it is not, change it to 449.500MHz.

• If the board number is 4221J01 thru 4221J06, 4221J36, or any other number not in the 4221J series, the transmit VCO crossover frequency in the “current value” box should be 438.025MHz. If it is not, change it to 438.025MHz.

VCO varactors (CR201, 203, 207, 208, and 209) in “C” and later kits are not interchangeable with VCO varactors in earlier kits; Motorola parts and part numbers are different. When replacing a VCO varactor, identify the UHF transceiver band split and the transceiver circuit board number, and then order replacement parts from the applicable parts list.

UHF, 450-520MHz Radios UHF transceiver board (450 - 520MHz band split) NUE7232 and

NUE7241 (“C” and later) kits include new VCO varactors, and are factory aligned with a new transmit VCO crossover frequency of

495.375MHz.

Page 48

Since the transmit crossover frequency has changed, whenever transmit VCO crossover alignment (an RSS function) is performed, UHF band split and circuit board identification will be important.

• UHF band split can positively be determined by the markings on the power amplifier shield. If the power amplifier shield marking is 25U04 or 85Y10, then the transceiver is a 403 - 470MHz band split. If the power amplifier shield marking is 25U05 or 85Y11, then the transceiver is a 450 - 520MHz band split.

Anytime a controller board or transceiver board is replaced in a radio, it will be necessary to perform the RSS transmit VCO crossover alignment, and check the transmit VCO crossover frequency.

Maintenance

Introduction This section of the manual describes preventive maintenance, safe

handling of CMOS devices, and repair procedures and techniques. Each of these topics provides information vital to the successful operation and maintenance of your radio.

Preventive Maintenance

In order to avoid operating outside the limits set by the FCC, it is recommended that the reference oscillator of the HT 1000, JT 1000, MT 2000, MTS 2000, and MTX radio be aligned every time the radio is disassembled, or once a year, whichever comes first. Periodic visual inspection and cleaning are also recommended.

Inspection Check that the external surfaces of the radio are clean, and that all

external controls and switches are functional. A detailed inspection of the interior electronic circuitry is not needed or desired.

Cleaning The following procedures describe the recommended cleaning agents

and the methods to be used when cleaning the external and internal surfaces of the radio. External surfaces include the front cover, chassis (rear cover), and battery case. These surfaces should be cleaned whenever a periodic visual inspection reveals the presence of smudges, grease, and/or grime. Internal surfaces should be cleaned only when the radio is disassembled for servicing or repair.

The only recommended agent for cleaning the external radio surfaces is a

0.5% solution of a mild dishwashing detergent, such as JOY®, in water. The only factory recommended liquid for cleaning the printed circuit boards and their components is isopropyl alcohol (70% by volume).

Cleaning External Plastic Surfaces

Cleaning Circuit Boards and Components

The effects of certain chemicals and their vapors

can have harmful results on certain plastics. Aerosol sprays, tuner cleaners, and other chemicals should be avoided.

C a u t i o n

The detergent-water solution should be applied sparingly with a stiff, non-metallic, short-bristled brush to work all loose dirt away from the radio. A soft, absorbent, lintless cloth or tissue should be used to remove the solution and dry the radio. Make sure that no water remains entrapped near the connectors, cracks, or crevices.

Isopropyl alcohol may be applied with a stiff, non-metallic, shortbristled brush to dislodge embedded or caked materials located in hard-to-reach areas. The brush stroke should direct the dislodged material out and away from the inside of the radio.

Page 64

Alcohol is a high-wetting liquid and can carry contamination into unwanted places if an excessive quantity is used. Make sure that controls or tunable components are not soaked with the liquid. Do not use high-pressure air to hasten the drying process, since this could cause the liquid to puddle and collect in unwanted places.

Upon completion of the cleaning process, use a soft, absorbent, lintless cloth to dry the area. Do not brush or apply any isopropyl alcohol to the frame, front cover, or back cover.

NOTE: Always use a fresh supply of alcohol and a

clean container to prevent contamination by dissolved material (from previous usage).

Safe Handling of CMOS Devices

Repair Procedures and Techniques

General

Parts Replacement and Substitution

Complementary metal-oxide semiconductor (CMOS) devices are used in this family of radios. While the benefits of CMOS are many, their characteristics make them susceptible to damage by electrostatic or high voltage charges. Damage can be latent, resulting in failures occurring weeks or months later. Therefore, you must take special precautions to prevent device damage during disassembly, troubleshooting, and repair. Handling precautions are mandatory for CMOS circuits, and are especially important in low humidity conditions. DO NOT attempt to disassemble the radio without first referring to the CMOS CAUTION paragraph in the Disassembly and Reassembly section of the manual.

Refer to the Disassembly and Reassembly section of the manual for pertinent information prior to replacing and substituting parts.

Special care should be taken to be as certain as possible that a suspected component is actually the one at fault. This special care will eliminate unnecessary unsoldering and removal of parts, which could damage or weaken other components or the printed circuit board itself.

Rigid Circuit Boards This family of radios uses bonded, multi-layer, printed circuit boards.

When damaged parts are replaced, identical parts should be used. If the identical replacement component is not locally available, check the parts list for the proper Motorola part number and order the component from the nearest Motorola Communications Parts office listed in the “Replacement Parts Ordering” section of this manual.

Since the inner layers are not accessible, some special considerations are required when soldering and unsoldering components. The printed-through holes may interconnect multiple layers of the printed circuit. Therefore, care should be exercised to avoid pulling the plated circuit out of the hole.

When soldering near the module socket pins, use care to avoid accidentally getting solder in the socket. Also, be careful not to form solder bridges between the module socket pins. Closely examine your

Page 65

work for shorts due to solder bridges. When removing modules with metal enclosures, be sure to desolder the enclosure ground tabs as well as the module pins.

Flexible Circuits The flexible circuits are made from a different material than the rigid

boards, and different techniques must be used when soldering. Excessive prolonged heat on the flexible circuit can damage the material. Avoid excessive heat and excessive bending. For parts replacement, use the ST-1087 Temperature-Controlled Solder Station with a 600 or 700 degree tip, and use small diameter solder such as ST-

633. The smaller size solder will melt faster and require less heat being applied to the circuit.

To replace a component on a flexible circuit, grasp the edge of the flexible circuit with seizers (hemostats) near the part to be removed, and pull gently. Apply the tip of the soldering iron to the component connections while pulling with the seizers. Do not attempt to puddle out components. Prolonged application of heat may damage the flexible circuit.

Specific During all repair procedures, heating neighboring components can be

minimized by:

• using upper heat only.

Strip Connector (P301/ P704)

• using the correct size heat-focus head, approximately the same size as the carrier being replaced.

• keeping the heat focus head approximately 1/8” above the printed circuit board when removing or replacing the device.

If neighboring PBGA components are heated

above 365 degrees F. (185 degrees C.), they will suffer die-bond delamination and possible “popcorn” failure.

C a u t i o n

On the latest version HT 1000, JT 1000, MT 2000, MTS 2000, and MTX series radios, a strip connector, two female connectors and a strain relief electrically connect the RF board with the controller board. On earlier versions of these radios, the RF board and controller board were connected using a jumper flex that soldered directly to the circuit board solder pads.

An interconnect kit, REX4350A, is available to retrofit earlier version jumper-flex radios with the later version strip connector parts. The REX4350A kit includes the following items:

• CONNECTOR, Female (J301) 0905461X01

• CONNECTOR, Female (J704) 0905461X01

• CONNECTOR, Male (P301/P704) 0905461X01

• STRAIN RELIEF 4205507X01

• INSTRUCTIONS 6880309F14

Page 66

Jumper Flex (on radios shipped prior to 7/94)

Jumper flexes are not available. They are replaced with connectors as described in paragraph “a” of this section. If the jumper flex needs to be replaced, order Interconnect Kit REX4350A. The retrofit kit includes all of the parts required and detailed instructions on the removal of the old jumper flex, and the installation of the new connector arrangement.

RF Switch (S101): Refer to the applicable exploded view and to your radio's RF board

(antenna contact area) to locate the RF switch components.

NOTE: The RF switch spring and the RF switch piston

must be ordered separately.

To Remove the RF Switch: 1. On VHF and UHF radios, unsolder the two tabs of the RF switch

bracket that secure the RF switch to the RF board. On 800MHz and 900MHz radios, use a #2 slotted screwdriver to straighten the two tabs of the RF switch bracket that wrap around the RF board. Use your forefinger to hold the RF switch bracket to the RF board while straightening the tabs to avoid lifting the solder tabs on the opposite end of the RF switch bracket.

2. Refer to Figure 16 and use a small heat-focus head to distribute heat over the area occupied by the three solder tabs until the solder softens.

3 Solder

Tabs

Figure 16 Solder Tabs

3. Carefully lift the RF switch assembly away from the rf board. Notice that the RF switch circuit board remains attached (soldered) to the RF board.

4. Using the same heat-focus head as in steps (2) and (3), unsolder the RF switch circuit board, and remove it from the RF board using forceps.

5. In the RF switch circuit board area, reflow all the solder pad areas on the main RF board such that similarly shaped pads have uniform solder heights. Add or remove solder as required. Clean the RF board thoroughly. Then swab on a minimum amount of flux to each of the solder pads.

To Replace the RF Switch: 1. Place the RF switch assembly on the RF main board and gently

heat. Visually inspect to make sure no flux migrated onto the gold plated areas of the RF switch board. The guide pins should provide self alignment between the two circuit boards. Visually inspect the

Page 67

plastic switch housing to ensure that it has not warped due to overheating.

2. While holding the RF switch bracket firmly against the RF board:

• VHF and UHF radios - solder the two leads of the housing to the solder pads on the RF board.

• 800MHZ and 900MHz radios - bend the two tabs around the side of the RF board as close to the board edge as possible to hold the bracket down tightly.

3. Insert the new RF switch spring and RF switch piston into the RF switch assembly. The contacts of the piston should be facing the gold-plated pads of the RF switch board. Once the spring and piston are inserted into the RF switch, they will be retained by the switch.

Chip Components Use either the RLN-4062 Hot-Air Repair Station or the Motorola

0180381B45 Repair Station for chip component replacement. When using the 0180381B45 Repair Station, select the TJ-65 mini-thermojet hand piece. On either unit, adjust the temperature control to 700 degrees F. (370 degrees C), and adjust the airflow to a minimum setting. Airflow can vary due to component density.

1. To remove a chip component, select a hot- air hand piece and position the nozzle of the hand piece approximately 1/8” (0.3cm) above the component to be removed. Begin applying the hot air. Once the solder reflows, remove the component using a pair of tweezers. Using solder wick and a soldering iron or a power desoldering station, remove the excess solder from the pads.

Plastic-Ball Grid-Array (PBGA), Over-Molded PadArray Carrier (OMPAC), and Glob Top Components

2. To replace a chip component using a soldering iron, select the appropriate micro-tipped soldering iron and apply fresh solder to one of the solder pads. Using a pair of tweezers, position the new chip component in place while heating the fresh solder. Once solder wicks onto the new component, remove the heat from the solder. Heat the remaining pad with the soldering iron and apply solder until it wicks to the component. If necessary, touch up the first side. All solder joints should be smooth and shiny.

3. To replace a chip component using hot air, select the hot-air hand piece and reflow the solder on the solder pads to smooth it. Apply a drop of solder paste flux to each pad. Using a pair of tweezers, position the new component in place. Position the hot-air hand piece approximately 1/8” (0.3cm) above the component and begin applying heat. Once the solder wicks to the component, remove the heat and inspect the repair. All joints should be smooth and shiny.

The term Plastic-Ball Grid-Array (PBGA) will be used to describe most of this products type of modules. PBGA modules may be the construction of an Over-Molded Pad-Array Carrier (OMPAC) component or “Glob Top” component. A U204 synthesizer component in one radio may be an OMPAC and the same U204 synthesizer in another radio may be a Glob Top. The two components look a little different, but are electrically the same and are interchangeable.

Page 68

C a u t i o n

If neighboring PBGA components are heated

C a u t i o n

above 365 degrees F. (185 degrees C.), they will suffer die-bond delamination and possible “popcorn” failure. To prevent this delamination problem, circuit boards to be repaired must be baked in an oven for eight hours at 260 degrees F. (125 degrees C.) prior to solder repairs.

All pad-array carriers in these radios, except for the IF IC (U3), are PBGA components. Prior to use, all PBGA components must be kept in the sealed bag (with moisture-indicator card) as supplied by the Motorola Parts Department. Once the sealed bag is opened and/or the PBGA component subjected to ambient humidity (for an unknown amount of time or for more than 96 hours) then that PBGA component must be baked in an oven for at least eight hours at 260 degrees F. (125 degrees C.)

During all repair procedures, heating neighboring components can be minimized by:

• using upper heat only.

• using the correct size heat-focus head, approximately the same size

as the carrier being replaced.

• keeping the heat focus head approximately 1/8”-1/4” (0.3cm-

0.6cm) above the printed circuit board when removing or replacing the device.

To Remove a PBGA Component, select the R-1319 Rework Station and the appropriate heat- focus head

(approximately the same size as the PBGA. Attach the heat-focus head to the chimney heater. Adjust the temperature control to approximately 415 degrees F (215 degrees C); 445 degrees F (230 degrees C) maximum. Apply the solder paste flux around the edge of the PBGA. Place the circuit board in the circuit board holder, and position the PBGA component under the heat-focus head. Lower the vacuum tip and attach it to the PBGA component by turning on the vacuum pump. Lower the heat-focus head until it is approximately 1/ 8”-1/4” (0.3cm-0.6cm) above the carrier. Turn on the heater and wait until the PBGA component lifts off the circuit board. Once the part is off, grab it with a pair of tweezers and turn off the vacuum pump. Remove the circuit board from the R-1319’s circuit board holder.

Page 69

The application of heat to the PBGA device, beginning at ambient air temperature and

C a u t i o n

ending with the PBGA component lifting from the circuit board, should take longer than 60 seconds. If the PBGA component lifts from the circuit board earlier than 60 seconds:

• check the temperature control setting on

• lift the heat-focus head an additional 1/8”

• check the circuit board plating for possible

the rework station, and if OK

from nominal setting, and

damage.

To Replace an PBGA component,

the solder pads on the board must first be cleaned of all solder to ensure alignment of the new chip carrier. Prepare the site by using solder wick and a soldering iron to remove all solder from the solder pads on the circuit board. If a power desoldering tool is available, it can be used instead of the solder wick. Clean the solder pads with alcohol and a small brush. Dry and inspect. Ensure that all solder is removed.

Once the preparation is complete, place the circuit board back in the circuit board holder. Add solder paste flux in the trench of the flux block and spread it using a one-inch putty knife. Flux the PBGA component by placing it in the trench of the flux block. Once the flux is applied, place the PBGA component on the circuit board, making certain that it is oriented correctly on the board. Position the heatfocus head over the PBGA component and lower it to approximately 1/8”-1/4” (0.3cm-0.6cm) over the carrier. Using the same heat setting used to remove the PBGA component, turn on the heater and wait for the carrier to reflow (heating and reflow should take longer than 60 seconds).Watch the PBGA component reflow and note that when a proper reflow has taken place, the PBGA component will drop (usually one side, then the other). The end result is that both sides have reflowed, and the PBGA component is sitting parallel to the circuit board.

Once the carrier reflows, raise the heat-focus head and wait approximately one minute for the part to cool. Remove the circuit board and inspect the repair. No cleaning should be necessary.

Thin Small Outline Package (TSOP) Components

Removing and Replacing a TSOP Component:

will be done with the R-1319, using the same procedure used to remove and replace an PBGA component.

Place the circuit board in the circuit board holder. Select the proper heat focus head and attach it to the heater chimney. Position the TSOP component under the heat-focus head. Lower the vacuum tip and attach it to the component by turning on the vacuum pump. Lower the focus head until it is approximately 1/8”-1/4” (0.3cm-0.6cm) above the component. Turn on the heater and wait until the TSOP lifts off the circuit board.

Shields

Once the part is off, turn off the heat, grab the part with a pair of tweezers, and turn off the vacuum pump. Prepare the circuit board for the new component by applying solder paste flux to the solder pads. Position the circuit board under the heat-focus head, lower the head to approximately 1/8”-1/4” (0.3cm-0.6cm) above the board, and turn on the heat. When the solder left behind on the pads reflows, turn off the heat and raise the heat-focus head. Remove the circuit board from the holder and inspect the pads to ensure that the solder has flattened out and that there are no solder shorts. Clean the area with alcohol and a small brush.

Once the preparation is complete, place the circuit board back in the circuit board holder. Add solder paste flux to the solder pads and place the new component on the circuit board. Position the heat-focus head over the component and lower it to approximately 1/8”-1/4” (0.3cm-

0.6cm) above the carrier. Turn on the heater and wait for the component to reflow.

Once the component reflows, raise the heat-focus head and wait approximately one minute for the part to cool. Remove the circuit board and inspect the repair. No cleaning should be necessary.

Removing and Replacing the Shields:

will be done with the R-1319, using the same procedure used to remove and replace TSOP and PBGA components.

Place the circuit board in the circuit board holder. Select the proper heat focus head and attach it to the heater chimney. Add solder paste flux around the base of the shield. Position the shield under the heatfocus head. Lower the vacuum tip and attach it to the shield by turning on the vacuum pump. Lower the focus head until it is approximately 1/8”-1/4” (0.3cm-0.6cm) above the shield. Turn on the heater and wait until the shield lifts off the circuit board. Once the shield is off, turn off the heat, grab the part with a pair of tweezers, and turn off the vacuum pump. Remove the circuit board from the circuit board holder.

To replace the shield, add solder to the shield if necessary, using a micro-tipped soldering iron. Next, rub the soldering iron tip along the edge of the shield to smooth out any excess solder. Use solder wick and a soldering iron to remove excess solder from the solder pads on the circuit board. Place the circuit board back in the circuit board holder. Place the shield on the circuit board using a pair of tweezers. Position the heat-focus head over the shield and lower it to approximately 1/ 8”-1/4” (0.3cm-0.6cm) above the shield. Turn on the heater and wait for the solder to reflow.

Once complete, turn off the heat, raise the heat-focus head, and wait approximately one minute for the part to cool. Remove the circuit board and inspect the repair. No cleaning should be necessary.

RF PA (U105) The procedure for removing and replacing the RF PA is very similar to

the procedure for removing and replacing an PBGA or a TSOP component. But because the device is large, extra heating time is required to flow the pads. And as a result, neighboring components (especially those on the opposite side of the circuit board) will heat,

Page 71

reflow, and may inadvertently move. Be careful when performing the following procedure.

Refer to Figure 17 for RF PA nomenclature.

Pads

Figure 17 RF PA Nomenclature

To Remove the RF PA, add flux to the leads of the device, and use a soldering iron and pair of

tweezers to heat and lift each lead free and clear of its respective solder pad on the circuit board. Use the R-1319 Rework Station and the heatfocus head designed especially for removal of the RF PA. Attach the heat-focus head to the chimney heater. Adjust the temperature control to approximately 415 degrees F (215 degrees C) 445 degrees F (230 degrees C) maximum. Apply solder paste to the exposed solder pads under the PA. Place the circuit board in the circuit board holder, and position the RF PA under the heat-focus head. Lower the heat-focus head until it is approximately 1/8”-1/4” (0.3cm-0.6cm) above the PA cover. Turn on the heater and begin the reflow cycle. Heating time should not be less than two minutes.

Once the part has reflowed, before trying to remove the PA, carefully lower the circuit board holder as follows:

• Loosen the thumbscrew on the shaft of the circuit board holder,

• push the spring-loaded holder down and away from the heat-focus

head, and

• retighten the thumbscrew with the holder in the bottomed position.

Grab the PA with a large pair of tweezers and remove it from the circuit board. Let the circuit board cool for approximately two minutes. Then remove the circuit board from the circuit board holder.

To Replace the RF PA; if necessary, add solder to the PA ground plane on the printed circuit

board. Then clean each PA lead solder pad on the circuit board to ensure alignment of the new RF PA. Prepare the sight by using solder wick and a soldering iron to remove all solder from the solder pads. Clean the solder pads with alcohol and a small brush. Dry and inspect. Ensure that all solder is removed.

Once the preparation is complete, place the circuit board back in the circuit board holder. Add solder paste flux to the ground plane and to the leads’ solder pads. Once the flux is applied, place the new RF PA on the circuit board, making certain that the PA heatsink sits flush on the board. Position the heat-focus head over the RF PA and lower it to approximately 1/8”-1/4” (0.3cm-0.6cm)) above the PA cover. Turn on

Page 72

the heater and begin the reflow cycle. Heating time should not be less than two minutes.

Once the RF PA reflows, raise the heat-focus head and wait approximately two minute for the part to cool. Remove the circuit board and inspect the solder joint between the slab and the ground plane. No cleaning should be necessary. Use the soldering iron and add solder to each of the RF PA leads and associated pads. Inspect the lead/ pad bond for opens and solder shorts.

Introduction

General Transceiver components and controller components reside on

separate circuit boards. Refer to the model charts located in the front of this manual (prior to Section 1) to determine the controller board and transceiver board unique to your model radio. Then locate the appropriate transceiver board and controller board component location diagram, schematic diagram, and parts list located in this section of the manual.

Component location diagrams of the controls flex, two front cover/ display flexes, and the strip connector are also located in this section. A miscellaneous parts list accompanies the flex circuits.

Almost all circuit boards in this family of radios are either six or eight layers. Layer 1 is the outer most layer viewed from side 1, and layer 6 or 8 (as applicable) is the outer most layer viewed from sine 2. A typical 8-layer circuit board detail, viewing copper steps in proper layer sequence, is illustrated in Figure 18.

Transceiver Frequently, transceivers that use a common transceiver board will be

combined into one component location diagram, one schematic diagram, and one parts list. The differences between transceivers will be noted throughout the applicable parts list.

Controller Frequently, controllers that use a common controller board will be

combined into one component location diagram, one schematic diagram, and one parts list. The differences between controllers will be noted throughout the applicable parts list.

Schematic and Circuit Board Notes

Most all of the schematic diagrams in this manual include specific notes. Typically the notes are colored red to make them stand-out

Page 80

from the overall schematic. The following two notes are general and apply to all schematic and circuit board applications.

1. Unless otherwise stated, resistor values are in ohms (k = 1000), capacitor values are in picofarads (pF) or microfarads (µF), and inductor values are in microhenrys (µH) or nanohenrys (nH).

2. DC voltages are measured from point indicated to chassis ground using a high impedance (10 megohm) Motorola DC voltmeter or equivalent. Transmitter measurements should be made with a

1.2uF choke in series with the voltage probe to prevent circuit loading.

Reference Designator Assignment

Interconnect Tie Point Legend

Reference designators are assigned in the following manner:

• Units Series = Receiver

• 100 SERIES = Transmitter

• 200 SERIES = Frequency Generation

• 300 SERIES = Miscellaneous

• 400 SERIES = Housing/Escutcheon

• 500 SERIES = Display

• 600 SERIES = Hear Clear Option

• 700 SERIES = Controller

5V REG = Regulated Five Volts B+ = Battery Voltage (7.5V) R5 = Receiver Five Volts T5 = Transmitter Five Volts CLK = Clock D=Data DAC = Digital To Analog Converter DAC RST = DAC Reset LCK = Lock NC = No Connection SYN = Synthesizer VR = Voltage Regulator

Integrated Circuit Details with Pin-Out Names

Because of today’s technology, integrated circuits and special modules are able to perform a vast amount of functions in a single component. The components are getting smaller and the number of IO pins is getting greater, to the point that there is not enough room to put enough IC information on the schematics and circuit boards. To help troubleshoot and signal trace this family of radios, several of the IC’s are detailed with pin-out names and illustrated on the next few pages.

Remember that PBGA components in a radio can be a combination of OMPAC and/or Glob Top. Although the illustrations on the next few pages reflect OMPAC devices, like Good-by components are electrically the same.
