I2C-bus controlled TV input processor
FUNCTIONAL DESCRIPTION Vision IF amplifier
The VIF amplifier contains three AC-coupled control stages with a total gain control range higher than 66 dB. The sensitivity of the circuit is comparable with that of modern IF-ICs.
The video signal is demodulated by a PLL carrier regenerator, which contains a frequency detector and a phase detector. During acquisition, the frequency detectortunesthe VCO to thecorrectfrequency.The initial adjustment of theoscillator is realized via theI2C-bus. The switching between SECAM L and L’ can also be realized via the I2C-bus. After lock-in, the phase detector controls the VCO so that a stable phase relationship between the VCO and the input signal is achieved. The VCO operates at twice the IF frequency. The reference signal for the demodulator is obtained by means of a frequency divider circuit. To get good performance for phase modulatedcarriersignals,the control speed of the PLLcan be increased by bit FFI.
TDA9321H
The input of the ident circuit is connected to pin 14 (see Fig.3). This has the advantage that the ident circuit can also be activated when a scrambled signal is received (descrambler connected between the IF video output (pins 10 and 14). A second advantage is that the ident circuit can be usedwhen the VIF amplifieris not used(e.g. with built-in satellite tuners). The video ident circuit can also be used to identify the selected CBVS or Y/C signal. Theswitchingbetween the two modescanberealizedwith bit VIM.
The TDA9321H contains a group delay correction circuit which can be switched between the BG and a flat group delayresponse characteristic. This hastheadvantage that no compromise has to be made in multistandard receivers for the choice of the SAW filter. Both the input and output of the group delay correction circuit are externally available, so that the sound trap can be connected between the IF video output and the group delay correction input. The output signal of the correction circuit can be supplied to the video processing circuit and to the external SCART plug.
The AFC output is obtained by using the VCO control voltage of the PLL and can be read via the I2C-bus. For fast search tuning systems, the window of the AFC can be increased with a factor 3. The setting is realized with bit AFW.
The AGC detector operates on top sync and top white level. The demodulation polarity is switched via the I2C-bus. The AGC detector time constant capacitor is connected externally: mainly because of the flexibility of the application. The time constant of the AGC system during positive modulation is rather long, to avoid visible variationsof the signalamplitude. To improvethe speed of the AGC system, a circuit is included that detects whether the AGC detector is activated every frame period. When no action is detected during three field periods, the speed of the system is increased. For signals without peak white information, the system automatically switches to a gated black level AGC. Because a black level clamp pulse is required for this mode of operation, the circuit only switches to black level AGC in the internal mode.
The circuit contains a video identification (ident) circuit which is independent of the synchronization circuit. Therefore, search tuning is possible when the display section of the receiver is used as a monitor. However, this ident circuit cannot be made as sensitive as the slower sync ident circuit (bit SL) and we recommend the use of both ident outputs to obtain a reliable search system. The ident output is supplied to the tuning system via the I2C-bus.
The IC has several(I2C-bus controlled) outputports which can be used to switch sound traps or other external components.
When the VIF amplifier is not used, the complete VIF amplifier can be switched off with bit IFO via the I2C-bus.

Sound circuit

The SIF amplifier is similar to the VIF amplifier and has a gain control range of approximately 66 dB. The AGC circuit is related to the SIF carrier levels (average level of AM or FM carriers) and ensures a constant signal amplitude of the AM demodulator and the QSS mixer.
The single referenceQSS mixer isrealized by a multiplier. This multiplier converts the SIF signal to the intercarrier frequency by mixing it with the regenerated picture carrier from the VCO. The mixer output signal is supplied to the output via a high-pass filter to attenuate the residual video signals. With this system, a high performance hi-fi stereo sound processing can be achieved.
TheAM sound demodulator isrealized by amultiplier. The modulatedSIF signal is multipliedin phase withthe limited SIF signal. The demodulator output signal is supplied to the output via a low-pass filter to attenuate the carrier harmonics.

Video switches

The circuit has three CVBS inputs (one internal and two external inputs) and two Y/C inputs. The Y/C inputs can also be used as additional CVBS inputs. The switch configuration is given in Fig.3. The various sources are selected via the I2C-bus.
The circuit can be set in a mode in which it automatically detects whether a CVBS or a Y/C signal is supplied to the Y/C inputs. In this mode, the TV standard is first identified on the added Y/CVBS and the C input signal. Then, both chrominance input signal amplitudes are checked once andthe input signalwith the highestburst signal amplitude is selected. The result of the detection can be read via the I2C-bus.
The IC has two inputs (AV1 and AV2), which can be used to read the status levels of pin 8 of the SCART plug. The information is available in the output status byte 02 in bits D0 to D3.
The three outputs of the video switch (CVBSTXT, CVBSPIP and COMBCVBS) can be independently switched to the various input signals. The names are just arbitrary and it is for instance possible to use the COMBCVBS signal todrive the combfilter and the teletext decoder in parallel and to supply the CVBSTXT signal to the SCART plug (via an emitter follower).
For comb filter interfacing, the circuit has the COMBCVBS output,athird Y/C input, a referencesignaloutput (fsc)and two control pins which switch the comb filter to the standard of the incoming signal (as detected by the ident circuit of the colour decoder). When the comb filter is enabledby bit ECMB andasignal is recognizedwhich can be combed, the Y/C signals coming from the comb filter are automatically selected if the original source is a CVBS signal, indicated via the CMB-bit in output status byte 02 (D5). For signals which cannot be combed (like SECAM or Black-to-White signals) and for Y/C input signals,theY/C signalscoming from the comb filter arenot selected.

Chrominance and luminance processing

The circuits contain a chrominance bandpass, a SECAM cloche filter and a chrominance trap circuit. The filters are realized by means of gyrator circuits and they are automatically calibrated by comparing the tuning frequency with the crystal frequency of the decoder. The luminance delay line is also realized by means of gyrator circuits. The centre frequency of the chrominance bandpass filter is switchable via the I2C-bus so that the performance can be optimized for ‘front-end’ signals and external CVBS signals.
TDA9321H
The luminance output signal which is derived from the incoming CVBS or Y/C signal can be varied in amplitude bymeans of aseparate gain settingcontrol via theI2C-bus control bits GAI1 and GAI0. The gain variation which can be realized with these bits is 1 to +2 dB.

Colour decoder

The colour decoder can decode PAL, NTSC and SECAM signals. The PAL/NTSC decoder contains an alignment-free crystal oscillator with four separate crystal pins, a killer circuit and two colour difference demodulators. The 90° phase shift for the reference signal is made internally.
Because it is possible to connect four different crystals to the colour decoder, all colour standards can be decoded without external switching circuits. Which crystals are connected to the decoder must be indicated via the I2C-bus. The crystal connection pins that are not used must be left open circuit.
The horizontal oscillator is calibrated by means of the crystal frequency of the colour PLL. For a reliable calibration, it is very important that crystal indication bits XA to XD are not corrupted. For this reason, the crystal bits can be read in the output bytes so that the software can check the I2C-bus transmission.
The ICs contain an Automatic Colour Limiting (ACL) circuit, which can be switched via the I2C-bus and which preventsoversaturationoccurringwhensignals with a high chrominance-to-burstratioarereceived. The ACL circuit is designed such that it only reduces the chrominance signal and not the burst signal. This has the advantage that the colour sensitivity is not affected by this function. The ACL function is mainly intended for NTSC signals but it can also beused forPAL signals. For SECAM signals, the ACL function should be switched off.
The SECAM decoder contains an auto-calibrating PLL demodulator which has two references: the4.43 MHz sub-carrier frequency (which is obtained from the crystal oscillator which is used to tune the PLL to the desired free-running frequency) and the bandgap reference (to obtain the correctabsolute valueof the output signal). The VCO of the PLL is calibrated during each vertical blanking period, when the IC is in search or SECAM mode.
The circuit can also decode the PALplus helper signal and can insert the various reference signals, set-ups and timing signals which are required for the PALplus decoder ICs.
The baseband delay line (TDA4665 function) is integrated.

RGB switch and matrix

The IC has two RGB inputs with fast switching. The switching of the various sources is controlled via the I2C-bus and the condition of the switch inputs can be read from the I2C-bus status bytes. If the RGB signals are not synchronous with the selected decoder input signal, an external clamp pulse has to be supplied to the HA/CLP input. The IC must be set in this mode via the I2C-bus. In this case, the VA pulse is suppressed by switching the VA output to a high impedance OFF state.
When an external RGB signal is mixed into the internal YUV signal, it is necessary to switch-off the PALplus demodulation. To detect the presence of a fast blanking, a circuit is added which forces the MACP and HD bits to zero if a blanking pulse is detected in two consecutive lines. This system is chosen to prevent switching off at every spike that is detected on the fast blanking input.
The IC can use input RGB1 as YUV input. This function can be enabled by bit YUV in subaddress 0A (D3). When switched to theYUV input, the input signals must have the same amplitude and polarity as the YUV output signals. The Y signal has to be supplied to the G1 input, the U signal to the B1 input and the V signal to the R1 input.
TDA9321H
If required, the IC can select the time constant, depending on the noise content of the incoming video signal.
The free-running frequency of the oscillator is determined by a digital control circuit, which is locked to the reference signal of the colour decoder. When the IC is switched on, the HA/CLP is suppressed and the oscillator is calibrated as soon as all sub-address bytes have been sent. When thefrequencyofthe oscillator is correct, the HA/CLPsignal is switched on again.
When the coincidence detector indicates an out-of-lock situation, the calibration procedure is repeated.
The VA pulse is obtained via a vertical countdown circuit. This circuit has various windows, depending on the incoming signal (50 or 60 Hz standard or no standard). The countdown circuit can be forced to various modes by means of the I2C-bus. To obtain short switching times of the countdown circuitduring a channelchange, the divider can be forced in the search window by means of bit NCIN.

C-BUS SPECIFICATION
I
The slave addresses of the ICs are given in Table 1. The circuit operates up to clock frequencies of 400 kHz.

Synchronization circuit

The sync separator is preceded by a controlled amplifier that adjusts the sync pulse amplitude to a fixed level. These pulses are fed to the slicing stage, which operates at 50% of the amplitude. The separated sync pulses are fed to the phase detector and to the coincidence detector. This detector detects whether the line oscillator is synchronized and can also be used for transmitter identification. This circuit can be made less sensitive by means of bit STM. This mode can be used during search tuning to avoid the tuning system from stopping at very weak input signals. The PLL has a very high static steepness so that the phase of the picture is independent of the line frequency.
Two conditions are possible for the horizontal output pulse:
An HA pulse which has a phase and width that are identical to the incoming horizontal sync pulse
A Clamp Pulse (CLP) which has a phase and width that are identical to the clamp pulse in the sandcastle pulse.
Signal HA/CLP is generated by an oscillator that runs at a frequency of 440 × fH. Its frequency is divided by 440 to lockthe first loopto the incomingsignal. The timeconstant of the loop can be forced by the I2C-bus (fast or slow).
Table 1 Slave addresses
A6 A5 A4 A3 A2 A1 A0 R/W
10001A111/0
Bit A1 is controlled via pin 48 (AS). When the pin is connected to ground, it is a logic 0; when connected to the positive supply line, it is a logic 1. When this pin is left open, it is connected to ground via an internal resistor.

Start-up procedure

Read the status bytes until POR = logic 0 and send all subaddress bytes. Check the bus transmission by reading output status bits SXA to SXD. This ensures good operation of the calibration system of the horizontal oscillator.Thehorizontal output signal is switched onwhen the oscillator is calibrated.
Read the status bytes each time before the data in the IC is refreshed. If POR = logic 1, the procedure mentioned above must be carried out to restart the IC. When this procedureis not followed,thehorizontal frequency may be incorrect after power-up or after a power dip.
The 00 to 0E subaddresses are valid. The FE and FF subaddresses are reserved for test purposes. The auto-increment mode is available for subaddresses.

0 crystal not present 1 crystal present; note 1
Note
1. When a comb filter is used, the various crystals must be connected to the IC as indicated in the pinning diagram. This is required because the ident system switches automatically tothe comb filter when asignal is identified which can be combed (correct combinationofcolour standard and crystalfrequency). For applications without comb filter only the crystal on pin XTALA is important (4.43 MHz); to pins XTALB to XTALD an arbitrary3.5 MHz crystal can be connected.

Notes
1. For an equal delay of the luminance and chrominance signal the delay must be set at a value of 280 ns (YD3 to YD0 = 1011). This is only valid for a CVBS signal without group delay distortions.
2. The total Y-delay is the addition of: YD3 + YD2 + YD1 + YD0.

Notes
1. When bit ECMB = 1 the subcarrier frequency is present on pin 30. The YCF and CCFsignals coming from the comb filter are only switched on when a signal is received that can be combed.
2. X = don’t care.
3. AUTO YC means the decoder switches between CVBS and Y/C depending on the presence of the burst signal on these signals.
4. AUTO COMB means the decoder switches to Y/C mode if the burst is present on the C input and to the comb filter output if the burst is present on the CVBS signal.

Notes to the characteristics
1. Thetwo supply pins VP1and VP2mustbe decoupled separatelybut they mustbe connected toa single powersupply to avoid too big differences between them.
2. On set AGC.
3. This parameter is not tested during production and is just given as application information for the designer of the television receiver.

4. Loop filter bandwidth B level as f
5. The optimum temperature stability of the PLL can be obtained when a TOKO coil as given in Table 55 is applied.
6. This parameter is not tested during production but is guaranteed by the design and qualified by means of matrix batches which are made in the pilot production period.
7. Measured at 10 mV (RMS) top sync input signal.
8. So called projected zero point, i.e. with switched demodulator.
9. Measured in accordance with the test line given in Fig.5. For the differential phase test the peak white setting is reduced to 87%.
The differential gain is expressed as a percentage of the difference in peak amplitudes between the largest and smallest value relative to the subcarrier amplitude at blanking level.
The differential phase is defined as the difference in degrees between the largest and smallest phase angle.
10. This figure is valid for the complete video signal amplitude (peak white-to-black). See Fig.6.
11. The noise inverter is only active in the ‘strong signal mode’ (no noise detected in the incoming signal).
12. The input conditions and test set-up are given in Figs 8 and 9. The figures are measured with an input signal of 10 mV (RMS).
13. Measured at an inputsignalof 10 mV (RMS). The S/Nis the ratio ofblack-to-whiteamplitude with respect tothe black level noise voltage (RMS value). B = 5 MHz. Weighted in accordance with CCIR 567.
14. The AGC response time also depends on the acquisition time of the PLL demodulator. The values given are valid when the PLL is in lock.
15. The AFC control voltage is obtained from the control voltage of the VCO of the PLL demodulator. The tuning information is supplied to the tuning system via the I2C-bus. Two bits are reserved for this function. The AFC value is valid only when bit PL = 1.
16. The weighted S/N ratio is measured under the following conditions: a) The VIF modulator must meet the following specifications:
Incidental phase modulation for black-to-white jumps less than 0.5 degrees.
QSS AF performance, measured with the television-demodulator AMF2 (audio output, weighted S/N ratio)
Picture-to-sound carrier ratio: PC/SC1 = 13 dB (transmitter).
b) The measurements must be carried out with the Siemens SAW filters G3962 for VIF and G9350 for SIF.
Input level for SIF at 10 mV (RMS) with 27 kHz deviation.
c) The PC/SC ratio at the VIF input is calculated asthe additionof the TV transmitter ratio and the SAW filter PC/SC
ratio. This PC/SC ratio is necessary to achieve the S/NW values as indicated.
17. Signal with negative-going sync. Amplitude includes sync pulse amplitude.
18. Indicated is a signal for a colour bar with 75% saturation (chrominance to burst amplitude ratio = 2.2 : 1).
19. When a signal is identified which can be combed (correct combination of colour standard and reference crystal) the comb filter is switched to that mode via pins 25 and 27 and then the filter is activated by switching on the reference carrier signal and connecting the output signals of the comb filter (pins 28 and 29) to the video processing circuits.
20. The subcarrier output signal can be used as a reference signal for external comb filter ICs (e.g. SAA4961). When bit ECMB = 0 the subcarrier signal is suppressed and the DC level is LOW. When bit ECMB = 1 the output level is HIGH and the subcarrier signal is present.
21. The outputs SYS1 and SYS2 can be used to switch the comb filter to the different colour standards (e.g. PAL-M, PAL-N, PAL-B/G and NTSC-M) and are controlled by the colour decoder identification circuit.
The setting of the outputs for the various standards is given in Table 56.

22. For the detection ofthe status oftheincoming SCART signala voltage divider witha ratio of2 : 3has to beconnected between pin 8 of the SCART plug and the detection input. The impedance of the voltage divider should not be too high-ohmic because of the input impedance of 100 k.
23. When the decoder is forced to a fixed subcarrier frequency (via bits XA to XD or bit CM) the chrominance trap is always switched on, also when no colour signal is identified. When 2 crystals are active the chrominance trap is switched off if no colour signal is identified.
24. The typical group delay characteristic for the B/G standard is given in Fig.7.
25. At a chrominance input voltage of 660 mV (p-p) [colour bar with 75% saturation i.e. burst signal amplitude 300 mV (p-p)] the dynamic range of the ACC is +6 and 20 dB.
26. The ACL function canbe activated by bit ACL.The ACL circuit reducesthe gain of thechrominance amplifier for input signals with a C/C
which exceeds a value of 3.0.

27. All frequency variations are referenced to 3.58 or 4.43 MHz carrier frequency. All oscillator specifications are measuredwith the Philipscrystalseries 9922 520 with aseries capacitance Cs= 18 pF.The oscillator circuitisrather insensitive to the spurious responses of the crystal. As long as the resonance resistance of the third overtone is higher than that of the fundamental frequency the oscillator will operate at the correct frequency. The typical crystal parameters for the crystal series are:
a) Load resonance frequencies fL: 4.433619, 3.579545, 3.582056 and 3.575611 MHz; Cs= 20 pF. b) Motional capacitance C
= 20.6 fF (4.43 MHz crystal) or C
mot
= 14.7 fF (3.58 MHz crystal).

c) Parallel capacitance Cp= 5.0 pF. The minimum detuning range can only be specified if both the IC and the crystal tolerances are known and therefore
the figures regarding catching range are only valid for the specified crystal series. In this figure tolerances of the crystal with respect to the nominal frequency, motional capacitance and ageing have been taken into account and have been counted for gaussic addition. Whenever different typical crystal parameters are used the following equation might be helpful for calculating the impact on the tuning capabilities:

The resulting detuning range should be corrected for temperature shift and supply voltage deviation of both the IC and the crystal. To guarantee a catching range of ±300 Hz on 4.43 MHz the minimum motional capacitance of the crystal must have a value 13.2 fF or higher. For a catching range of 250 Hz with the 3.58 MHz crystal the minimum motional capacitance must have a value of 9 fF. Note: SMD-type crystals do not fulfil these requirements. The actual series capacitance in the application should be C
= 18 pF to account for parasitic capacitances on-chip
s
and off-chip.
28. Thehue control isactivefor NTSC on thedemodulatedcolour difference signals andforPALplus on the demodulated helper signal.
29. This parameter indicates the bandwidth of the complete chrominance circuit including the chrominance band-pass filter. The bandwidth of the low-pass filter of the demodulator is approximately 1 MHz.
30. This delay is partially caused by the low-pass filter at the sync separator input.
31. The internal luminance signal (signal which is derived from the incoming CVBS or Y/C signals) has a separate gain control setting (controlledby the I2C-bus bits GAI1 and GAI0and with a gain variation between 1 and +2 dB)which can be used to get an optimal input signal amplitude for the feature box.
32. The slicing level is independent of sync pulse amplitude. The given percentage is the distance between the slicing level and the black level (back porch). When the amplitude of the sync pulse exceeds the value of 350 mV the sync separator will slice the sync pulse at a level of 175 mV above top sync. The maximum sync pulse amplitude is 4 V (peak-to-peak value).

33. To obtain a good performance for both weak signal and VCR playback the time constant of the first control loop is switched depending on the input signal condition and the condition of the I2C-bus. Therefore the circuit contains a noisedetector and the timeconstant is switched tothe slow mode whentoo much noise ispresentin the signal.In the fast mode during the vertical retrace time the phase detector current is increased 50% so that phase errors due to head-switching of the VCR are corrected as soon as possible. Switching between the two modes can be automatic or overruled by the I2C-bus.
Thecircuit contains avideo identification circuitwhich is independent ofthe first controlloop. This identification circuit can be used to close or open the first control loop when a video signal is present or not present on the input. This enables a stable On Screen Display (OSD) when just noise is present at the input. The coupling of the video identification circuit with the first control loop can be revoked via the I2C-bus.
To prevent the horizontal synchronization being disturbed by anti copy signals such as Macrovision the phase detector is gated during the vertical retrace period from line 11 to 17 (60 Hz signal) or from line 11 to 22 (50 Hz signal) so that pulses during scan have no effect on the output voltage. The width of the gate pulse is approximately 22 µs. During weak signal conditions (noise detector active) the gating is active during the complete scan period and the width of the gate pulse is reduced to 5.7 µs so that the effect of noise is reduced to a minimum.
The output current of the phase detector in the various conditions is shown in Table 57.
34. The timing pulses for the vertical ramp generator are obtained from the horizontal oscillator via a divider circuit. This divider circuit has 3 modes of operation:
a) Search mode large window.
This mode is switched on when the circuit is not synchronized or when a non-standard signal [number of lines per frame outside the range between 311 and 314 (50 Hz mode) or between 261 and 264 (60 Hz mode)] is received. In the search mode the divider can be triggered between line 244 and line 361 (approximately
43.3 to 64.5 Hz).
b) Standard mode narrow window.
This mode is switched on whenmore than 15 succeedingvertical sync pulsesare detected in the narrow window. When the circuit is in the standard mode and a vertical sync pulse is missing the retrace of the vertical ramp generator is started at the end of the window. Consequently, the disturbance of the picture is very small. The circuit will switch back to the search window when, for 6 successive vertical periods, no sync pulses are found within the window.
c) Standard TV-norm [divider ratio 525 (60 Hz) or 625 (50 Hz)].
When the system is switched to the narrow window a check is performed to establish whether the incoming vertical sync pulses are in accordance with the TV-norm. When 15 standard TV-norm pulses are counted the divider system is switched to the standard divider ratio mode. In this mode the divider is always reset at the standard value even if the vertical sync pulse is missing.
When 3 vertical sync pulses are missed the system switches back to the narrow window and when also in this window no sync pulses are found (condition 3 missing pulses) the system switches over to the search window.
The vertical divider needs some waiting time during channel-switching of the tuner. When a fast reaction of the divider is required during channel-switching the system can be forced to the search window by means of bit NCIN in subaddress 06.
35. The delay between the positive edge of VA and the positive edge of CLP (negative edge of HA)after VA is 32.0 µs forfield 1 and 0 µsfor field 2. Especiallyfor PALplus signals theregenerated VA pulsesmust have afixedand known phase relation to the undisturbed VA pulses of the incoming video signal. This relationship must remain correct as long as the vertical divider is in the standard mode (indirect sync mode). Therefore the coincidence window used here must be a half line window. With a well defined phase relationship of the generated VA pulses to the generated HA pulses a correct field identification and all the required timing signals referring to a certain line in each frame can be generated externally in the PALplus decoder environment.
36. Pins 19 and 22 are for general purpose outputs that can be used to switch external circuits e.g. sound traps, etc. They are controlled via the I2C-bus by bits OS0 (pin 19) and OS1 (pin 22).

SOLDERING Introduction to soldering surface mount packages
Thistext gives a very briefinsightto a complex technology. A more in-depth account of soldering ICs can be found in our
“Data Handbook IC26; Integrated Circuit Packages”
(document order number 9398 652 90011). There is no soldering method that is ideal for all surface
mount IC packages.Wave soldering isnot always suitable for surface mount ICs, or for printed-circuit boards with high population densities. In these situations reflow soldering is often used.
Reflow soldering
Reflow soldering requires solder paste (a suspension of fine solder particles, flux and binding agent) to be applied tothe printed-circuit boardbyscreen printing, stencilling or pressure-syringe dispensing before package placement.
Several methods exist for reflowing; for example, infrared/convection heating in a conveyor type oven. Throughput times (preheating,soldering and cooling) vary between 100 and 200 seconds depending on heating method.
Typical reflow peak temperatures range from 215 to 250 °C. The top-surface temperature of the packages should preferable be kept below 230 °C.
Wave soldering
Conventional single wave soldering is not recommended forsurfacemount devices (SMDs) orprinted-circuitboards with a high component density, as solder bridging and non-wetting can present major problems.
To overcome these problems the double-wave soldering method was specifically developed.
TDA9321H
If wave soldering is used the following conditions must be observed for optimal results:
Use a double-wave soldering method comprising a turbulent wave with high upward pressure followed by a smooth laminar wave.
For packages with leads on two sides and a pitch (e): – larger than or equal to 1.27 mm, the footprint
longitudinal axis is preferred to be parallel to the transport direction of the printed-circuit board;
– smaller than 1.27 mm, the footprint longitudinal axis
must be parallel to the transport direction of the printed-circuit board.
The footprint must incorporate solder thieves at the downstream end.
Forpackageswith leads on foursides,thefootprint must be placed at a 45° angle to the transport direction of the printed-circuit board. The footprint must incorporate solder thieves downstream and at the side corners.
During placement andbefore soldering, the package must be fixed with a droplet of adhesive. The adhesive can be applied by screen printing, pin transfer or syringe dispensing. The package can be soldered after the adhesive is cured.
Typical dwell time is 4 seconds at 250 °C. A mildly-activated flux will eliminate the need for removal of corrosive residues in most applications.
Manual soldering
Fix the component by first soldering two diagonally-opposite end leads. Use a low voltage (24 V or less) soldering iron applied to the flat part of the lead. Contact time must be limited to 10 seconds at up to 300 °C.
When using a dedicated tool, all other leads can be soldered in one operation within 2 to 5 seconds between 270 and 320 °C.

Notes
1. All surface mount (SMD) packages are moisture sensitive. Depending upon the moisture content, the maximum temperature (with respect to time) and body size of the package, there is a risk that internal or external package cracks may occur due to vaporization of the moisture in them (the so called popcorn effect). For details, refer to the Drypack information in the
“Data Handbook IC26; Integrated Circuit Packages; Section: Packing Methods”
.
2. These packages are not suitable for wave soldering as a solder joint between the printed-circuit board and heatsink (at bottom version) can not be achieved, and as solder may stick to the heatsink (on top version).
3. If wave soldering is considered, then the package must be placed at a 45° angle to the solder wave direction. The package footprint must incorporate solder thieves downstream and at the side corners.
4. Wave soldering is only suitable for LQFP, TQFP and QFP packages with a pitch (e) equal to or larger than 0.8 mm; it is definitely not suitable for packages with a pitch (e) equal to or smaller than 0.65 mm.
5. Wave soldering is only suitable for SSOP and TSSOP packageswith a pitch (e) equal to or larger than 0.65 mm; it is definitely not suitable for packages with a pitch (e) equal to or smaller than 0.5 mm.
