FUNCTIONAL DESCRIPTION Vision IF amplifier
The VIF amplifier contains 3 AC-coupled control stages with a total gain control range which is 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. This circuit contains a frequency detector and a phase detector. During acquisition the frequency detector will tune the VCO to the correct frequency. The initial adjustment of the oscillator is realized via the I
2
C-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 a good performance for phase modulated carrier signals the control speed of the PLL can be increased by bit FFI.
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; this is mainly because of the flexibility of the application. The time constant of the AGC system during positive modulation is rather long, this is to avoid visible variations of the signal amplitude. To improve the speed of the AGC system a circuit has been included which detects whether the AGC detector is activated every frame period. When, during 3 field periods, no action is detected the speed of the system is increased. For signals without peak white information the system switches automatically to a gated black level AGC. Because a black level clamp pulse is required for this mode of operation the circuit will only switch to black level AGC in the internal mode.
The circuits contain 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). It is recommended to use both ident outputs to obtain a reliable search system. The ident output is supplied to the tuning system via the I2C-bus.
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 made operative when a scrambled signal is received (descrambler connected between pins 10 and 14). A second advantage is that the ident circuit can be used when the VIF amplifier is 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. The switching between the 2 modes can be realized with bit VIM.
The TDA9321H contains a group delay correction circuit which can be switched between the BG and a flat group delay response characteristic. This has the advantage that in multistandard receivers no compromise has to be made 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 VIF output and the group delay correction input. The output signal of the correction circuit can be supplied to the internal video processing circuit and to the external SCART plug.
The IC has several (I
2
C-bus controlled) output ports 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.
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 to the AM demodulator and the QSS mixer.
The single reference QSS mixer is realized by a multiplier. In this multiplier the SIF signal is converted 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 for attenuation of the residual video signals. With this system a high performance hi-fi stereo sound processing can be achieved.
The AM sound demodulator is realized by a multiplier. The modulated SIF signal is multiplied in phase with the limited SIF signal. The demodulator output signal is supplied to the output via a low-pass filter for attenuation of the carrier harmonics.

TDA9321H
Video switches
The circuit has 3 CVBS inputs (1 internal and 2 externals) and 2 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 can be 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 identification first takes place on the added Y/CVBS and the C input signal. Then both chrominance input signal amplitudes are checked once and the input signal with the highest burst signal amplitude is selected. The result of the detection can be read via the I
2
C-bus.
The IC has 2 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 3 outputs of the video switches (CVBSCF, CVBSTXT and CVBSPIP) can be independently switched to the various input signals. The names are just arbitrary and it is, for instance, possible to use the CVBSCF signal to drive the comb filter 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 CVBSCF output, a 3rd Y/C input, a reference signal output REFO and 2 control pins (SYS1 and SYS2) which switch the comb filter to the standard of the incoming signal (as detected by the ident circuit of the colour decoder). When a signal is recognized which can be combed and the comb filter is enabled by bit ECMB the Y/C signals coming from the comb filter are automatically selected. This is indicated via bit CMB in output status byte 02 (D5). For signals which cannot be combed (such as SECAM or black-to-white signals) the Y/C signals coming from the comb filter are not selected.
Chrominance and luminance processing
The circuits contain a chrominance band-pass, 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 band-pass filter is switchable via the I
2
C-bus so that the performance can be optimized for ‘front-end’ signals and external CVBS signals.
The luminance output signal which is derived from the incoming CVBS or Y/C signal can be varied in amplitude by means of a separate gain setting control via the I
2
C-bus control bits GAI1 and GAI0. The gain variation which can be realized with these bits is 1to+2dB.
Colour decoder
The colour decoder can decode PAL, NTSC and SECAM signals. The PAL/NTSC decoder contains an alignment-free crystal oscillator with 4 separate pins for crystal connection, a killer circuit and two colour difference demodulators. The 90° phase shift for the reference signal is produced internally.
Because it is possible to connect 4 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 I
2
C-bus. The crystal connection pins which 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 the crystal indication bits XA to XD are not corrupted. For this reason bits XA to XD can be read in the output bytes so that the software can check the I2C-bus transmission.
The IC contains an Automatic Colour Limiting (ACL) circuit which is switchable via the I2C-bus and prevents oversaturation occuring when signals with a high chrominance-to-burst ratio are received. 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 be used for PAL signals. For SECAM signals the ACL function should be switched off.
The SECAM decoder contains an auto-calibrating PLL demodulator which has two references: the 4.43 MHz subcarrier frequency which is obtained from the crystal oscillator which is used to tune the PLL to the desired free-running frequency and the band gap reference to obtain the correct absolute value of 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.

I2C-bus controlled TV input processor
TDA9321H
RGB switch and matrix
The IC has 2 RGB inputs with fast switching. The switching of the various sourcing 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 that case the vertical pulse is suppressed by switching the VA output in a high-impedance off-state.
When an external RGB signal is mixed with 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 bits MACP and HD to zero if a blanking pulse is detected in 2 consecutive lines. This system is chosen to prevent switching-off at every spike which is detected on the fast blanking input.
The IC has the possibility to use the RGB1 input as YUV input. This function can be enabled by means of bit YUV in subaddress 0A (D3). When switched to the YUV 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 GI1 input, the U signal to the BI1 input and the V signal to the RI1 input.
Synchronization circuit
The sync separator is preceded by a controlled amplifier which 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 coincidence detector is used to detect whether the line oscillator is synchronized and can also be used for transmitter identification. This circuit can be made less sensitive with bit STM. This mode can be used during search tuning to avoid the tuning system stopping at very weak input signals. The PLL has a very high statical steepness so that the phase of the picture is independent of the line frequency.
For the horizontal output pulse 2 conditions are possible:
An HA pulse which has a phase and width which is identical to the incoming horizontal sync pulse
A clamp pulse (CLP) which has a phase and width which is identical to the clamp pulse in the sandcastle pulse.
The HA/CLP signal is generated by means of an oscillator which is running at a frequency of 440 × f
hor
. Its frequency is divided by 440 to lock the first loop to the incoming signal. The time constant of the loop can be forced by the I2C-bus (fast or slow).
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 subaddress bytes have been sent. When the frequency of the oscillator is correct the HA/CLP signal 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 count-down circuit. The count-down circuit has various windows depending on the incoming signal (50 or 60 Hz standard or non-standard). The count-down circuit can be forced in various modes via the I
2
C-bus. To obtain short switching times of the count-down circuit during a channel change the divider can be forced in the search window by means of bit NCIN.

C-BUS SPECIFICATION
The slave address of the IC is given in Table 1. Bit A1 is controlled via pin AS. When pin AS is connected to pin GND2 it is at logic 0 and when connected to VP2 it is at logic 1. When pin AS is left open-circuit it is connected to ground via an internal pull-up resistor. The circuit operates at clock frequencies of up to 400 kHz.
Table 1 Slave address bits
Start-up procedure
Read the status bytes until bit POR = 0 and send all subaddress bytes. It is advised to check the I
2
C-bus transmission by reading the output status bits SXA to SXD. This ensures a good operation of the calibration system of the horizontal oscillator. The horizontal output signal is switched on when the oscillator is calibrated.
Each time before the data in the IC is refreshed, the status bytes must be read. If bit POR = 1, then the procedure mentioned above must be carried out to restart the IC. When this procedure is not carried out the horizontal frequency may be incorrect after power-up or after a power dip.
The valid subaddresses are 00 to 0E. Subaddresses FE and FF are reserved for test purposes. Auto-increment mode is available for the subaddresses.

Table 4 Crystal indication
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 to the comb filter when a signal is identified which can be combed (correct combination of colour standard and crystal frequency). For applications without comb filter only the crystal on pin XTALA is important (4.43 MHz); to pins XTALB to XTALD an arbitrary 3.5 MHz crystal can be connected.

Notes
1. When bit ECMB = 1 the subcarrier frequency is present on pin 30. The YCF and CCF signals 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. The two supply pins VP1and VP2 must be decoupled separately but they must be connected to a single power supply 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

input signal level). LC-VCO circuit between pins 7 and 8: Q0= 60; C
int
= 30 pF.
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 value) 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 value). The intermodulation figures are defined:
; α
0.92
value at 0.92 MHz referenced to black or white signal;
; α
2.76
value at 2.76 MHz referenced to colour carrier.
13. Measured at an input signal of 10 mV (RMS value). The S/N is the ratio of black-to-white amplitude with respect to the 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)
better than 60 dB (deviation 27 kHz) for 6 kHz sine wave black-to-white modulation.
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 value) with 27 kHz deviation.
c) The PC/SC ratio at the VIF input is calculated as the addition of 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 of the status of the incoming SCART signal a voltage divider with a ratio of 2 : 3 has to be connected 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 can be activated by bit ACL. The ACL circuit reduces the gain of the chrominance amplifier for input signals with a C/C
ACL
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 measured with the Philips crystal series 9922 520 with a series capacitance Cs= 18 pF. The oscillator circuit is rather 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
mot
= 20.6 fF (4.43 MHz crystal) or C
mot
= 14.7 fF (3.58 MHz crystal).
c) Parallel capacitance C
p
= 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:
Detuning range =
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. The actual series capacitance in the application should be C
s
= 18 pF to account for parasitic capacitances on-chip and off-chip.
28. The hue control is active for NTSC on the demodulated colour difference signals and for PALplus 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 (controlled by the I2C-bus bits GAI1 and GAI0 and 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 noise detector and the time constant is switched to the slow mode when too much noise is present in 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.
The circuit contains a video identification circuit which is independent of the first control loop. 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 when more than 15 succeeding vertical sync pulses are 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 for field 1 and 0 µs for field 2. Especially for PALplus signals the regenerated VA pulses must have a fixed and 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
This text gives a very brief insight to 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 is not 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 to the printed-circuit board by screen 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 for surface mount devices (SMDs) or printed-circuit boards 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.
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.
For packages with leads on four sides, the footprint 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 and before 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.

Suitability of surface mount IC packages for wave and reflow soldering methods
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 packages with 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.
