Notes
1. Values of video and sound parameters can be decreased at VP = 4.5 V.
2. For applications without I2C-bus, the time constant (R × C) at the supply must be >1.2 µs (e.g. 1 Ω and 2.2 µF).
3. Condition: luminance range (5 steps) from 0 % to 100 %.
4. AC load: CL < 20 pF and RL > 1 kΩ. The sound carrier frequencies (depending on the TV standard) are attenuated
by the integrated sound carrier traps (see Figs 15 to 20; H (s) is the absolute value of transfer function).
5. S/NW is the ratio of the black-to-white amplitude to the black level noise voltage (RMS value measured on pin CVBS).
B = 5 MHz weighted in accordance with “CCIR 567”.

FUNCTIONAL DESCRIPTION
• VIF amplifier
For negative modulation, the sync level voltage is stored at
an integrated capacitor by means of a fast peak detector.
This voltage is compared with a reference voltage
(nominal sync level) by a comparator which charges or
discharges the integrated AGC capacitor for the
generation of the required VIF gain. The time constants for
decreasing or increasing the gain are nearly equal and the
total AGC reaction time is fast to cope with ‘aeroplane
fluttering’.
• Tuner AGC and VIF-AGC
• VIF-AGC detector
• Frequency Phase-Locked Loop (FPLL) detector
• VCO and divider
• AFC and digital acquisition help
• Video demodulator and amplifier
• Sound carrier trap
For positive modulation, the white peak level voltage is
compared with a reference voltage (nominal white level)
by a comparator which charges (fast) or discharges (slow)
the external AGC capacitor directly for the generation of
the required VIF gain. The need of a very long time
constant for VIF gain increase is because the peak white
level may appear only once in a field. In order to reduce
this time constant, an additional level detector increases
the discharging current of the AGC capacitor (fast mode)
in the event of a decreasing VIF amplitude step controlled
by the detected actual black level voltage. The threshold
level for fast mode AGC is typically −6 dB video amplitude.
The fast mode state is also transferred to the SIF-AGC
detector for speed-up. In case of missing peak white
pulses, the VIF gain increase is limited to typically +3 dB
by comparing the detected actual black level voltage with
a corresponding reference voltage.
• SIF amplifier
• SIF-AGC detector
• Single reference QSS mixer
• AM demodulator
• FM demodulator and acquisition help
• Audio amplifier and mute time constant
• Radio mode
• Internal voltage stabilizer
• I2C-bus transceiver and MAD (module address).
VIF amplifier
The VIF amplifier consists of three AC-coupled differential
stages. Gain control is performed by emitter degeneration.
The total gain control range is typically 66 dB. The
differential input impedance is typically 2 kΩ in parallel with
3 pF.
8.2
8.4
FPLL detector
The VIF amplifier output signal is fed into a frequency
detector and into a phase detector via a limiting amplifier
for removing the video AM.
Tuner AGC and VIF-AGC
This block adapts the voltages, generated at the VIF-AGC
and SIF-AGC detectors, to the internal signal processing
at the VIF and SIF amplifiers and performs the tuner AGC
control current generation. The onset of the tuner AGC
control current generation can be set either via the I2C-bus
(see Table 13) or optionally by a potentiometer at pin TOP
(in case that the I2C-bus information cannot be stored).
The presence of a potentiometer is automatically detected
and the I2C-bus setting is disabled.
During acquisition the frequency detector produces a
current proportional to the frequency difference between
the VIF and the VCO signals. After frequency lock-in the
phase detector produces a current proportional to the
phase difference between the VIF and the VCO signals.
The currents from the frequency and phase detectors are
charged into the loop filter which controls the VIF VCO and
locks it to the frequency and phase of the VIF carrier.
For a positive modulated VIF signal, the charging currents
are gated by the composite sync in order to avoid signal
distortion in case of overmodulation. The gating depth is
switchable via the I2C-bus.
Furthermore, derived from the AGC detector voltage, a
comparator is used to test if the corresponding VIF input
voltage is higher than 200 µV. This information can be
read out via the I2C-bus (bit VIFLEV = 1).

VIF-AGC detector
Gain control is performed by sync level detection (negative
modulation) or peak white detection (positive modulation).
Figure 1 shows the simplified block diagram of the device
which comprises the following functional blocks:

TDA9887

Philips Semiconductors
Product specification
I2C-bus controlled multistandard alignment-free
IF-PLL demodulator with FM radio
8.5
8.7
VCO and divider
The demodulator output signal is fed into the video
preamplifier via a level shift stage with integrated low-pass
filter to achieve carrier harmonics attenuation.
The oscillator frequency is divided-by-two to provide two
differential square wave signals with exactly 90 degrees
phase difference, independent of the frequency, for use in
the FPLL detectors, the video demodulator and the
intercarrier mixer.
The output signal of the preamplifier is fed to the VIF-AGC
detector (see Section 8.3) and in the sound trap mode also
fed internally to the integrated sound carrier trap
(see Section 8.8). The differential trap output signal is
converted and amplified by the following postamplifier.
The video output level at pin CVBS is 2 V (p-p).
AFC and digital acquisition help
Each relaxation oscillator of the VIF-PLL and FM-PLL
demodulator has a wide frequency range. To prevent false
locking of the PLLs and with respect to the catching range,
the digital acquisition help provides an individual control,
until the frequency of the VCO is within the preselected
standard dependent lock-in window of the PLL.
In the bypass mode the output signal of the preamplifier is
fed directly through the postamplifier to pin CVBS. The
output video level is 1.1 V (p-p) for using an external sound
trap with 10 % overall loss.
Noise clipping is provided in both cases.
The in-window and out-window control at the FM-PLL is
additionally used to mute the audio stage (if auto mute is
selected via the I2C-bus).
8.8
Sound carrier trap
The sound carrier trap consists of a reference filter, a
phase detector and the sound trap itself.
The working principle of the digital acquisition help is as
follows. The PLL VCO output is connected to a down
counter which has a predefined start value (standard
dependent). The VCO frequency clocks the down counter
for a fixed gate time. Thereafter, the down counter stop
value is analysed. In case the stop value is higher (lower)
than the expected value range, the VCO frequency is
lower (higher) than the wanted lock-in window frequency
range. A positive (negative) control current is injected into
the PLL loop filter and consequently the VCO frequency is
increased (decreased) and a new counting cycle starts.
A sound carrier reference signal is fed into the reference
low-pass filter and is shifted by nominal 90 degrees. The
phase detector compares the original reference signal with
the signal shifted by the reference filter and produces a
DC voltage by charging or discharging an integrated
capacitor with a current proportional to the phase
difference between both signals, respectively to the
frequency error of the integrated filters. The DC voltage
controls the frequency position of the reference filter and
the sound trap. So the accurate frequency position for the
different standards is set by the sound carrier reference
signal.
The gate time as well as the control logic of the acquisition
help circuit is dependent on the precision of the reference
signal at pin REF. Operation as a crystal oscillator is
possible as well as connecting this input via a serial
capacitor to an external reference frequency, e.g. the
tuning system oscillator.
The sound trap itself is constructed of three separate traps
to realize sufficient suppression of the first and second
sound carriers.

The AFC signal is derived from the corresponding down
counter stop value after a counting cycle. The last four bits
are latched and can be read out via the I2C-bus
(see Table 7). Also the digital-to-analog converted value is
given as current at pin AFC.

Video demodulator and amplifier
The video demodulator is realized by a multiplier which is
designed for low distortion and large bandwidth. The VIF
signal is multiplied with the ‘in phase’ signal of the VIF-PLL
VCO.
The VCO of the VIF-FPLL operates as an integrated low
radiation relaxation oscillator at double the picture carrier
frequency. The control voltage, required to tune the VCO
to double the picture carrier frequency, is generated at the
loop filter by the frequency phase detector. The possible
frequency range is 50 to 140 MHz (typical value).

TDA9887
SIF amplifier
The SIF amplifier consists of three AC-coupled differential
stages. Gain control is performed by emitter degeneration.
The total gain control range is typically 66 dB. The
differential input impedance is typically 2 kΩ in parallel with
3 pF.

SIF-AGC detector
AM demodulator
The amplitude modulated SIF amplifier output signal is fed
both to a two-stage limiting amplifier that removes the AM
and to a linear multiplier. The result of the multiplication of
the SIF signal with the limiter output signal is
AM demodulation (passive synchronous demodulator).
The demodulator output signal is fed via a low-pass filter
that attenuates the carrier harmonics and via the input
amplifier of the SIF-AGC detector to the audio amplifier.
SIF gain control is performed by the detection of the
DC component of the AM demodulator output signal. This
DC signal corresponds directly to the SIF voltage at the
output of the SIF amplifier so that a constant SIF signal is
supplied to the AM demodulator and to the single
reference QSS mixer.
By switching the gain of the input amplifier of the SIF-AGC
detector via the I2C-bus, the internal SIF level for
FM sound is 5.5 dB lower than for AM sound. This is to
adapt the SIF-AGC characteristic to the VIF-AGC
characteristic. The adaption is ideal for a picture-to-sound
FM carrier ratio of 13 dB.
8.13
FM demodulator and acquisition help
The narrow-band FM-PLL detector consists of:
• Gain controlled FM amplifier and AGC detector
• Narrow-band PLL.
Via a comparator, the integrated AGC capacitor is charged
or discharged for the generation of the required SIF gain.
Due to AM sound, the AGC reaction time is slow
(fc < 20 Hz for the closed AGC loop). For reducing this
AM sound time constant in the event of a decreasing
IF amplitude step, the load current of the AGC capacitor is
increased (fast mode) when the VIF-AGC detector (at
positive modulation mode) operates in the fast mode too.
An additional circuit (threshold approximately 7 dB)
ensures a very fast gain reduction for a large increasing
IF amplitude step.
8.11
TDA9887
The intercarrier signal from the intercarrier mixer or from
pin FMIN is fed to the input of an AC-coupled gain
controlled amplifier with two stages. The gain controlled
output signal is fed to the phase detector of the
narrow-band FM-PLL (FM demodulator). For good
selectivity and robustness against disturbance caused by
the video signal, a high linearity of the gain controlled
FM amplifier and of the phase detector as well as a
constant signal level are required. The gain control is done
by means of an ‘in phase’ demodulator for the FM carrier
(from the output of the FM amplifier). The demodulation
output is fed into a comparator for charging or discharging
the integrated AGC capacitor. This leads to a mean value
AGC loop to control the gain of the FM amplifier.
Single reference QSS mixer
With the present system a high performance Hi-Fi stereo
sound processing can be achieved. For a simplified
application without a SIF SAW filter, the single reference
QSS mixer can be switched to the intercarrier mode via the
I2C-bus.
The FM demodulator is realized as a narrow-band PLL
with an external loop filter, which provides the necessary
selectivity (bandwidth approximately 100 kHz). To achieve
good selectivity, a linear phase detector and a constant
input level are required. The gain controlled intercarrier
signal from the FM amplifier is fed to the phase detector.
The phase detector controls via the loop filter the
integrated low radiation relaxation oscillator. The designed
frequency range is from 4 to 7 MHz.
The single reference QSS mixer generates the 2nd FM
TV sound intercarrier signal. It is realized by a linear
multiplier which multiplies the SIF amplifier output signal
and the VIF-PLL VCO signal (90 degrees output) which is
locked to the picture carrier. In this way the QSS mixer
operates as a quadrature mixer in the intercarrier mode
and provides suppression of the low frequency video
signals.
The VCO within the FM-PLL is phase-locked to the
incoming 2nd SIF signal, which is frequency modulated.
As well as this, the VCO control voltage is superimposed
by the AF voltage. Therefore, the VCO tracks with the FM
of the 2nd SIF signal. So, the AF voltage is present at the
loop filter and is typically 5 mV (RMS) for 27 kHz
FM deviation. This AF signal is fed via a buffer to the audio
amplifier.
The QSS mixer output signal is fed internally via a
high-pass and low-pass combination to the
FM demodulator as well as via an operational amplifier to
the intercarrier output pin SIOMAD.
The correct locking of the PLL is supported by the digital
acquisition help circuit (see Section 8.6).

Philips Semiconductors
Product specification
I2C-bus controlled multistandard alignment-free
IF-PLL demodulator with FM radio
8.14
delivers a constant 44 MHz signal (derived from the
reference signal of 4 MHz) for the down-conversion of the
first radio IF to 10.7 MHz. This signal is fed via the external
ceramic band-pass filter to the FM demodulator. The
demodulated AF signal is amplified by the audio amplifier.
Audio amplifier and mute time constant
The audio amplifier consists of two parts:
• AF preamplifier
• AF output amplifier.
In case of NTSC application (M/N standard) the internal
mixing frequency is 52 MHz. So, the first radio IF has to be
41.3 MHz.
The AF preamplifier used for FM sound is an operational
amplifier with internal feedback, high gain and high
common mode rejection. The AF voltage from the
PLL demodulator is 5 mV (RMS) for a frequency deviation
of 27 kHz and is amplified by 30 dB. By the use of a
DC operating point control circuit (with external
capacitor CAF), the AF preamplifier is decoupled from the
PLL DC voltage. The low-pass characteristic of the
amplifier reduces the harmonics of the sound intercarrier
signal at the AF output terminal.
In the radio mode, the tuner AGC is derived from the
SIF-AGC.
For tuning search mode, the device offers certain
monitoring functions. Switchable are radio AFC, FM-AGC
or SIF-AGC to pin AFC.
8.16
For FM sound a switchable de-emphasis network (with
external capacitor) is implemented between the
preamplifier and the output amplifier.
8.17
I2C-bus transceiver and module address
The device can be controlled via the 2-wire I2C-bus by a
microcontroller. Two wires carry serial data (SDA) and
serial clock (SCL) information between the devices
connected to the I2C-bus.
Switching to the mute state is controlled automatically,
dependent on the digital acquisition help in case the VCO
of the FM-PLL is not in the required frequency window.
This is done by a time constant: fast for switching to the
mute state and slow (typically 40 ms) for switching to the
no-mute state.
The device has an I2C-bus slave transceiver with
auto-increment. The circuit operates up to clock
frequencies of 400 kHz.
All switching functions are controlled via the I2C-bus:
A slave address is sent from the master to the slave
receiver. To avoid conflicts in a real application with other
devices providing similar or complementing functions,
there are four possible slave addresses available. These
Module Addresses (MADs) can be selected by connecting
resistors on pin SIOMAD and/or pins SIF1 and SIF2 (see
Fig.25). Pin SIOMAD relates with bit A0 and pins SIF1
and SIF2 relate with bit A3. The slave addresses of this
device are given in Table 1.
• AM sound, FM sound and forced mute
• Auto mute enable or disable
• De-emphasis off or on with 50 or 75 µs
• Audio gain normal or reduced.
Radio mode
The principle is to multiply the first radio IF (e.g. 33.3 MHz
at tuner output) with 44 MHz reference signal. The result
of the down-conversion is the second radio IF (10.7 MHz)
at intercarrier output.
The power-on preset value is dependent on the use of
pin SIOMAD and can be chosen for 45.75 MHz NTSC as
default (pin SIOMAD left open-circuit) or 58.75 MHz NTSC
(resistor on pin SIOMAD). In this way the device can be
used without the I2C-bus as an NTSC only device.
In the radio mode the tuner delivers a first radio IF signal
of 33.3 MHz. This signal is fed via the SIF SAW filter
(conventional used for QSS TV sound processing) to the
SIF input. The sound IF amplifier supplies this radio
IF signal by means of gain control with constant level to the
QSS mixer. The single reference QSS mixer generates the
second radio IF signal of 10.7 MHz. In the radio mode the
VIF VCO operates as part of a frequency synthesizer and
2004 Aug 25
Internal voltage stabilizer
The band gap circuit internally generates a voltage of
approximately 2.4 V, independent of supply voltage and
temperature. A voltage regulator circuit, connected to this
voltage, produces a constant voltage of 3.55 V which is
used as an internal reference voltage.
The AF output amplifier provides the required AF output
level by a rail-to-rail output stage. A preceding stage
makes use of an input selector for switching between
FM sound, AM sound and mute state. The gain can be
switched between 10 dB (normal) and 4 dB (reduced).
8.15
TDA9887
Remark: In case of using the device without the I2C-bus,
then the rise time of the supply voltage after switching on
power must be longer than 1.2 µs.

Notes
1. Values of video and sound parameters can be decreased at VP = 4.5 V.
2. Level headroom for input level jumps during gain control setting.
3. This parameter is not tested during the production and is only given as application information for designing the
receiver circuit.
4. Loop bandwidth BL = 70 kHz (damping factor d = 1.9; calculated with sync level within gain control range).
Calculation of the VIF-PLL filter can be done by use of the following formula:
1
BL –3dB = ------- K O K D R , valid for d ≥ 1.2
2π

d = --- R K O K D C ,

KO is the VCO steepness  -------- or  2π ------- ; KD is the phase detector steepness

 V
V
µA 
 ------;
 rad-
R is the loop resistor; C is the loop capacitor; BL−3dB is the loop bandwidth for −3 dB; d is the damping factor.
5. Vi(VIF) = 10 mV (RMS); ∆f = 1 MHz (VCO frequency offset related to picture carrier frequency); white picture video
modulation.
6. Condition: luminance range (5 steps) from 0 % to 100 %.
7. S/N is the ratio of black-to-white amplitude to the black level noise voltage (RMS value on pin CVBS). B = 5 MHz
(B/G, I and D/K standard). Noise analyzer setting: 200 kHz high-pass and SC-trap switched on.
8. The intermodulation figures are defined for:
V 0 at 4.4 MHz
a) f = 1.1 MHz (referenced to black and white signal) as α IM = 20 log  ------------------------------------- + 3.6 dB

9. Measurements taken with SAW filter M1963M (sound shelf: 20 dB); loop bandwidth BL = 70 kHz.
a) Modulation Vestigial Side-Band (VSB); sound carrier off; fvideo > 0.5 MHz.
b) Sound carrier on; fvideo = 10 kHz to 10 MHz.
10. AC load; CL < 20 pF and RL > 1 kΩ. The sound carrier frequencies (depending on TV standard) are attenuated by
the integrated sound carrier traps (see Figs 15 to 20; H (s) is the absolute value of transfer function).
11. The sound carrier trap can be bypassed by switching the I2C-bus. In this way the full composite video spectrum
appears at pin CVBS. The amplitude is 1.1 V (p-p).
12. If selected by the I2C-bus, the VIF-AGC voltage can be monitored at pin OP2, and pin OP1 can be used as input. In
this case, both pins cannot be used for the normal port function.
13. The response time is valid for a VIF input level range from 200 µV to 70 mV.
14. To match the AFC output signal to different tuning systems a current source output is provided. The test circuit is
given in Fig.11. The AFC steepness can be changed by resistors R1 and R2.
15. The tolerance of the reference frequency determines the accuracy of the VIF-AFC, FM demodulator centre
frequency and maximum FM deviation.
16. The intercarrier output signal at pin SIOMAD can be calculated by the following formula taking into account the
internal video signal with 1.1 V (p-p) as a reference:
1
r
V o(intc)(rms) = 1.1 × ----------- × 10 V
2 2
V i(SC)
1
and r = ------ ×  -------------- ( dB ) + 6 dB ± 3 dB

20  V i(PC)
where:
V i ( SC )
1
----------- is the correction term for RMS value, --------------- ( dB ) is the sound-to-picture carrier ratio at pins VIF1 and VIF2
V i ( PC )
2 2
in dB, 6 dB is the correction term of internal circuitry and ±3 dB is the tolerance of video output and intercarrier output
Vo(intc)(rms).
17. For normal operation (with the I2C-bus) no DC load at pin SIOMAD is allowed. The second module address (MAD2)
will be activated by the application of a 2.2 kΩ resistor between pin SIOMAD and ground. If this MAD2 is activated,
also the power-on set-up state activates a VIF frequency of 58.75 MHz.
18. SIF input level is 10 mV (RMS); VIF input level is 10 mV (RMS) unmodulated.
19. Measured with an FM deviation of 25 kHz and the typical AF output voltage of 500 mV (RMS). The AF output signal
can be attenuated by 6 dB to 250 mV (RMS) via the I2C-bus. For handling a frequency deviation of more than 55 kHz,
the AF output signal has to be reduced in order to avoid clipping (THD < 1.5 %).
20. The lower limit of the audio bandwidth depends on the value of the capacitor at pin AFD. A value of CAF = 470 nF
leads to fAF(−3dB) ≈ 20 Hz and CAF = 220 nF leads to fAF(−3dB) ≈ 40 Hz.
21. For all S/N measurements the VIF modulator in use has to meet the following specifications:
a) Incidental phase modulation for black-to-white jump less than 0.5 degrees.
b) QSS AF performance, measured with the television demodulator AMF2 (audio output, weighted S/N ratio) better
than 60 dB (at deviation 27 kHz) for 6 kHz sine wave black-to-white video modulation.
c) Picture-to-sound carrier ratio PC/SC1 = 13 dB (transmitter).

22. Calculation of the loop filter parameters can be done approximately using the following formulae:
1 KO KD
f o = ------- --------------2π C P
1
ϑ = -----------------------------------2R K O K D C P
2
BL –3dB = f o ( 1.55 – ϑ )
The formulae are only valid under the following conditions:
ϑ ≤ 1 and CS > 5CP
where:

KO is the VCO steepness  -------- or  2π ------- ;
 V

V
µA
KD is the phase detector steepness  -------- ;
 rad
R is the loop resistor;
CS is the series capacitor;
CP is the parallel capacitor;
fo is the natural frequency of the PLL;
BL−3dB is the loop bandwidth for −3 dB;
ϑ is the damping factor. For examples, see Table 20.
23. The PC/SC ratio is calculated as the addition of TV transmitter PC/SC1 ratio and SAW filter PC/SC1 ratio. This PC/SC
ratio is necessary to achieve the S/NW values as noted. A different PC/SC ratio will change these values.
24. Measurements taken with SAW filter G1984 (Siemens) for vision and sound IF (sound shelf: 14 dB).
Picture-to-sound carrier ratio of transmitter PC/SC = 13 dB. Input level on pins VIF1 and VIF2 of
Vi(SIF) = 10 mV (RMS) sync level, 27 kHz FM deviation for sound carrier, fAF = 400 Hz. Measurements in accordance
with “CCIR 468”. De-emphasis is 50 µs.
25. The QSS signal output on pin SIOMAD is analysed by a test demodulator TDA9820. The S/N ratio of this device is
more than 60 dB, related to a deviation of ±27 kHz, in accordance with “CCIR 468”.
26. Measurements taken with SAW filter K3953 for vision IF (suppressed sound carrier) and K9453 for sound IF
(suppressed picture carrier). Input level Vi(SIF) = 10 mV (RMS), 27 kHz (54 % FM deviation).
27. Measurements taken with SAW filter K9453 (Siemens) for AM sound IF (suppressed picture carrier).
28. The value of Cx determines the accuracy of the resonance frequency of the crystal. It depends on the type of crystal
used.
29. Pin REF is able to operate as a 1-pin crystal oscillator input as well as an external reference signal input, e.g. from
the tuning system.
30. The SDA and SCL lines will not be pulled down if VCC is switched off.
31. The AC characteristics are in accordance with the I2C-bus specification for fast mode (maximum clock frequency is
400 kHz). Information about the I2C-bus can be found in the brochure “The I2C-bus and how to use it” (order number
9398 393 40011).
32. Port P1 and port P2 are open-collector outputs.

To overcome these problems the double-wave soldering
method was specifically developed.
15 SOLDERING
15.1
Introduction to soldering surface mount
packages
If wave soldering is used the following conditions must be
observed for optimal results:
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).
• 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):
There is no soldering method that is ideal for all surface
mount IC packages. Wave soldering can still be used for
certain surface mount ICs, but it is not suitable for fine pitch
SMDs. In these situations reflow soldering is
recommended.
15.2
TDA9887
– 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.
Reflow soldering
The footprint must incorporate solder thieves at the
downstream end.
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.
Driven by legislation and environmental forces the
worldwide use of lead-free solder pastes is increasing.
• 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.
Several methods exist for reflowing; for example,
convection or convection/infrared heating in a conveyor
type oven. Throughput times (preheating, soldering and
cooling) vary between 100 seconds and 200 seconds
depending on heating method.
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 reflow peak temperatures range from
215 °C to 270 °C depending on solder paste material. The
top-surface temperature of the packages should
preferably be kept:
Typical dwell time of the leads in the wave ranges from
3 seconds to 4 seconds at 250 °C or 265 °C, depending
on solder material applied, SnPb or Pb-free respectively.
• below 225 °C (SnPb process) or below 245 °C (Pb-free
process)
A mildly-activated flux will eliminate the need for removal
of corrosive residues in most applications.
– for all BGA, HTSSON-T and SSOP-T packages
15.4
– for packages with a thickness ≥ 2.5 mm
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.
– for packages with a thickness < 2.5 mm and a
volume ≥ 350 mm3 so called thick/large packages.
• below 240 °C (SnPb process) or below 260 °C (Pb-free
process) for packages with a thickness < 2.5 mm and a
volume < 350 mm3 so called small/thin packages.
When using a dedicated tool, all other leads can be
soldered in one operation within 2 seconds to 5 seconds
between 270 °C and 320 °C.
Moisture sensitivity precautions, as indicated on packing,
must be respected at all times.
15.3
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

Notes
1. For more detailed information on the BGA packages refer to the “(LF)BGA Application Note” (AN01026); order a copy
from your Philips Semiconductors sales office.
2. 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”.
3. These transparent plastic packages are extremely sensitive to reflow soldering conditions and must on no account
be processed through more than one soldering cycle or subjected to infrared reflow soldering with peak temperature
exceeding 217 °C ± 10 °C measured in the atmosphere of the reflow oven. The package body peak temperature
must be kept as low as possible.
4. These packages are not suitable for wave soldering. On versions with the heatsink on the bottom side, the solder
cannot penetrate between the printed-circuit board and the heatsink. On versions with the heatsink on the top side,
the solder might be deposited on the heatsink surface.
5. 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.
6. Wave soldering is suitable for LQFP, TQFP and QFP packages with a pitch (e) larger than 0.8 mm; it is definitely not
suitable for packages with a pitch (e) equal to or smaller than 0.65 mm.
7. Wave soldering is suitable for SSOP, TSSOP, VSO and VSSOP 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.
8. Image sensor packages in principle should not be soldered. They are mounted in sockets or delivered pre-mounted
on flex foil. However, the image sensor package can be mounted by the client on a flex foil by using a hot bar
soldering process. The appropriate soldering profile can be provided on request.
9. Hot bar or manual soldering is suitable for PMFP packages.
