TDA9605H
Record-mute mode or head identification
selection
The state of the RM control signal on pin RMHID is don’t
care in the playback mode.
Pin RMHID allows input of two independent digital control
signals for selecting the record-mute or head identification
modes which are voltage coded. The RM control signal is
selected via a 10 kΩ resistor and the HID control signal is
selected via a 18 kΩ resistor. This set-up enables the two
signals within the TDA9605H to be separated. The RM
control signal is only in use during the record mode
(bit AFM = 1); during the playback mode (bit AFM = 0) the
RM signal is ignored. Pin RMHID should be connected to
ground when the RM control signal is not used.
I2C-bus control bits HAC2, HAC1 and HAC0 offer a wide
selection of playback amplification to fit different head and
head transformer specifications. The advised setting of the
playback amplification realizes a level of 24 mV (RMS) for
each carrier signal after the head amplifier to obtain a
17 dB overhead compared to the auto-normal level (hi-fi
detection). However, performance is not critical and a
different setting can be used if desired.
6.1
The carrier level can be measured using the HF envelope
output voltage on pin ENVOUT (bit EOS = 1). During
standard operating mode the HF envelope signal is
derived from the left channel carrier amplitude
(1.3 or 1.4 MHz carrier) but the special test 10 of the test
mode also enables the HF envelope output of the right
channel carrier amplitude (1.7 or 1.8 MHz carrier).
The advised carrier playback level of 24 mV (RMS) equals
an HF envelope voltage of 3.3 V.
The use of the RM control signal is optional since the same
function is available via the I2C-bus control in the
record-mute mode. However, accurate timing of recording
start and stop may sometimes be difficult to realize via the
I2C-bus control. In this event the RM control signal can be
used instead. There is also the possibility to use the
record-mute mode control line of the video head amplifier.
6.2
The head amplifier output signal can be monitored directly
by using test 8 of the test mode. Pin ENVOUT functions as
the test output showing 6 dB attenuation compared to the
actual head amplifier output level (see Section 14.4).
Hi-fi audio output level
When the application circuit is used in accordance with the
application diagram, the standard FM deviation of 50 kHz
equals a 1 kHz audio signal of −8 dBV line output level
(bit LOH = 0). A different standard audio level can be
selected by changing the external filter components of the
noise reduction on pins EMPHL and EMPHR
(see Section 14.3). The standard audio level changes
proportionally to the impedance of the external
de-emphasis filter.

RECORD-MUTE MODE
The record-mute mode is selected by setting bit AFM = 1
and either setting bits DOC, SHH and DETH to logic 0 or
switching the RM control signal to HIGH-level.
Head amplifier
During the record-mute mode no recording current is
present on pin RECOUT (see Fig.6). The head amplifier
status actually equals the playback mode, however, the
second amplifier stage is disabled to minimize power
consumption.
PLAYBACK MODE
The playback mode is selected by setting bit AFM = 0.
During the playback mode the input circuit on pins PBIN2
and PBIN1 is enabled (see Fig.6). Pin RECOUT is
disabled and pin HMSW shows a low impedance to
ground, so realizing an AC ground for the head circuit via
the external capacitor connected between these pins.
The RM control signal on pin RMHID enables fast
switching between the record and record-mute modes
(see Table 2). If the I2C-bus control is set to the record
mode, the use of record-mute mode control via pin RM
allows for accurate timing of recording start and stop,
independent of the I2C-bus control (see Section 6.1).
The head identification (HID) signal on pin RMHID selects
between the head signals on pins PBIN2 or PBIN1. Head
selection is defined as shown in Table 1.

A Boucherot damping circuit is connected between
pin HMSW and ground to prevent head current resonance
peaking. A capacitor of 10 nF and a resistor of 470 Ω are
specified in Fig.14, but the component values are not
critical.
RECORD MODE
6.4.4
The record mode is selected by setting bit AFM = 1 and
setting bits DOC, SHH and DETH from logic 001 to 111
and switching the RM control signal to LOW-level.
HEAD AMPLIFIER POWER SUPPLY AND GROUND
The head amplifier is supplied via a separate 5 V supply
(pin VCCH) and ground (pin GNDH).
During the record mode actual recording is activated and
the recording current is output on pin RECOUT
(see Fig.6). Pins PBIN2 and PBIN1 form a connection to
the 5 V head amplifier supply voltage (VCCH). Pin HMSW
is internally connected to pin RECOUT and the external
capacitor has no function in this mode.
A capacitor of 100 nF should be placed close to the device
between pins VCCH and GNDH for proper decoupling of
the power supply.
The head amplifier ground (pin GNDH) should be
connected to the main ground (pin GND).
The desired carrier mix ratio is set via I2C-bus control
bits DOC, SHH and DETH. A wide selection of recording
currents is available to fit different head and head
transformer specifications and are set via bits HAC2,
HAC1, HAC0 and range bit HRL. The setting of the carrier
mix ratio does not change the selected recording current.

frequency difference between the left and right channel
carrier near to 401.2 kHz. This value effectively reduces
the crosstalk from hi-fi carriers to video colour signal as
present during Extended Play (EP) tape speed. NTSC
calibration uses a standard HID control signal of 29.97 Hz
(pulse width =16.683 ms) where PAL calibration uses a
standard HID control signal of 25 Hz (pulse
width = 20 ms). After auto-calibration the maximum
frequency error is ±5 kHz assuming a time error of
maximum of 5 µs when the HID control signal is at
HIGH-level. Jitter on the HID control signal should not
exceed 1 µs to realize EP optimization within ±2 kHz for
NTSC. In general, the crystal based HID control signal
available in the video recorder can be used without
modification.
Automatic calibration
The integrated auto-calibration system is activated by
means of bit CALS of the power byte (see Fig.7).
The auto-calibration system ensures hi-fi processing is
well in accordance with the VHS hi-fi system standard by
an automated adjustment of carrier frequencies,
band-pass filters and noise reduction filters. Calibration is
only needed after start-up of the video recorder.
The calibration settings remain stable as long as the
supply voltage (VCC) is present.
Auto-calibration is only executed in the record-mute mode
or record mode and no standby mode or test mode should
be selected, i.e. auto-calibration requires the setting of
bit AFM = 1, bit STBP = 0, bit STBA = 0 and bit TEST = 0.
Auto-calibration is started after setting bit CALS = 1.
Calibration is performed fully automatically, using the HID
control signal as a time reference. Audio signals are not
disturbed during the calibration process.
When the calibration of the oscillators is completed the
band-pass filters are calibrated. The integrated weighting
and FM de-emphasis filters of the noise reduction are
calibrated at the same time.
Calibration of the oscillator frequencies is performed by
measuring the number of oscillator cycles within one
period when the HID control signal is at HIGH-level and
comparing this result with an internal value stored in the
Read Only Memory (ROM). Four different ROM values are
available for NTSC or PAL (SECAM) system calibration of
both the left and right channel carrier.
The total auto-calibration time needed is maximum
17 cycles of the HID control signal. Completion of the
calibration is signalled by bit CALR =1 of the read byte.
The calibration can also be monitored by means of the
envelope output. For this purpose the voltage on
pin ENVOUT is forced to >2.5 V during the calibration.
The audio signal to the audio envelope function (level
meter) should be muted (i.e. output select = mute).
In case of NTSC a special routine is active for the
calibration of the right channel carrier which results in a

Otherwise, the audio envelope output voltage may
become >2.5 V which makes it impossible to detect the
completion of the calibration on pin ENVOUT.

TDA9605H
Power muting
Switching off and on of the power supply voltage or using
the built-in passive standby mode results in rising and
dropping of the output DC voltages and causes strong
disturbances on the output pins. The TDA9605H includes
three integrated mute switches to block such disturbances
so avoiding the need for an external mute circuit. Pop-free
line and RF converter output signals are realized by
connecting the integrated power mute switches behind the
line and RFC output capacitors.
Calibration relies upon the frequency accuracy of the HID
control signal. The calibration result may be incorrect
when the HID control signal is disturbed during a critical
part of the calibration. An additional check is incorporated
to detect such a situation by reading bit CALE during
calibration. When bit CALE = 1, the calibration result is
detected to be unreliable due to external causes. A new
auto-calibration can be started by setting bit CALS = 0
followed by setting bit CALS = 1. Bit CALE always reads
logic 1 when bit CALS is logic 0.
Power muting is active when bit MUTE = 1 (see Fig.8).
Power muting is automatically activated when VCC is
switched on, because this situation is the Power-on reset
default state. The integrated mute switches on
pins MUTEC, MUTEL and MUTER are closed and form a
low-impedance path to ground. Furthermore, the
pins RFCOUT, LINEL and LINER are current limited to
−1 mA to avoid excessive supply currents and to achieve
good noise attenuation without the need for a series
resistor between the output and mute pins. Pins DECL and
DECR are also current limited for using the integrated
power mute switches or for assisting external muting.
The oscillators and band-pass filters can be switched
between NTSC and PAL system frequencies after a
calibration in NTSC or PAL mode without the need of
additional calibration. Switching between these system
modes is executed immediately and can be done in any
operating mode. The frequency accuracy of system
switching is 100 ±3 kHz for both carriers. To obtain the
best possible frequency accuracy in the record mode it is
good practice to recalibrate after system switching.

During power muting the internal output signal is also
muted. After the output DC voltage has been established
power muting can be de-activated by setting bit MUTE = 0.
Now the mute switches are opened resulting in a
high-impedance path of 100 kΩ to ground. The output
current limiting is not active.
6.7
During the playback mode the selection between audio
level and carrier level information is realized by setting
I2C-bus control bit EOS (see Table 3). The AF envelope
output is defined by the signal selection made at the output
select.
During the record mode bit EOS offers the selection
between the audio level of the output select or the audio
level of the fixed hi-fi stereo signal. This is a helpful setting
when the microcontroller uses the audio level information
to adjust the hi-fi recording level (volume control).
It should be noted that the time needed for stabilizing the
output DC voltage is proportional to the output capacitor
value. A safe mute time is 200 ms using a 10 µF capacitor
(tmute = C × 20000 s). Power muting consumes
approximately 4 mA additional supply current, so to obtain
minimum power consumption the mute mode should be
de-activated after use. Very good performance is achieved
for power-up, power-down and passive standby mode
switching.
The HF envelope output signal is continuous and is
derived from the left channel carrier. The HF envelope
output exhibits a logarithmic characteristic (see Fig.11).
In a standard application circuit only the left channel carrier
level is required to support auto-tracking or manual
tracking. However, test 10 of the special test mode allows
for the right channel carrier level output instead for
measurement purposes (see Section 14.4).
An auto-mute function is included which activates power
muting when the supply voltage drops below 7 V.
The performance of this auto-mute function depends upon
the power voltage drop rate. The voltage drop rate should
not exceed 1 V during 10 ms. The best performance
independent of voltage drop rate is realized by activating
the passive standby mode before switching off the power
supply voltage (by setting bit MUTE = 1 and bit STBP = 1).
The AF envelope output as a function of the output level is
given in Fig.12.
The AF envelope circuit uses time multiplexing for the left
and right channel audio level. A peak-hold function and
dynamic range compression (square root function) are
included for easy read out. The peak-hold function and the
left and right channel multiplexing are controlled by the
HID control signal on pin RMHID (see Table 4).

Envelope output
Pin ENVOUT is an analog output for stereo audio level
(e.g. level meter display) and for playback FM carrier level
(e.g. auto-tracking). The functional diagram is given in
Fig.9 and the timing diagram is shown in Fig.10. Only one
ADC input is needed on the microcontroller for reading all
the required information.
Power muting is also used in combination with the
integrated passive standby mode (bit STBP = 1). During
this mode the output circuits are switched off and the line,
decoder and RF converter output voltages decrease to 0 V
using a discharge current of 1 mA. Do not set power mute
mode and change the passive standby mode at the same
time. Power mute mode should be activated first, followed
by switching on or off of the passive standby mode to avoid
possible output glitches.

The circuit changes into a mixing desk when using the
dub-mix mode of the input select function in combination
with the volume setting of normal select. A new linear
audio recording can be created by mixing together the new
and the original sound.
Audio dubbing
The TDA9605H includes unparalleled functionality
supporting the audio dubbing function of hi-fi video
recorders. Audio dubbing is a feature which enables the
recording of new sound material on the linear audio track
(i.e. normal sound) of an existing recording. The dub-mix
mode is selected by setting bit IS2 = 1, bit IS1 = 0 and
bit IS0 = 1. Audio dubbing can be used in two different
ways:
Continuous user control over amplitude and ratio mix of
the auxiliary input signal (e.g. a microphone input) and the
original hi-fi playback sound is possible using the left and
right channel volume controls. This function is realized
inside the IC by connecting the auxiliary input signal pair
(pins AUXL and AUXR) to the left channel volume control
and the hi-fi output signal pair to the right channel volume
control.
• Output mix
• Input mix.
6.9.1
OUTPUT MIX
The settings of the output select function are used to
arrange the hi-fi selection and the output signals in the
dub-mix mode. However, some of these settings are
overruled in the dub-mix mode. The normal signal is
available on the line outputs for monitoring the dub-mix
recording signals in the output select function modes
mix-left, mix-right and mix-stereo.
A new additional recording is made on the linear audio
track. In the playback mode, the new linear audio sound
and the original hi-fi sound are combined. In this way the
hi-fi stereo quality remains and the linear audio sound is
partly used (e.g. for commentary only). However, there is
no control over the original hi-fi sound.
Mixing of the hi-fi and normal sound signals in the playback
mode is supported by the output select function mix-left,
mix-right and mix-stereo (bits OSN, OSR and OSL) and
creates a new fixed output signal of 1⁄2 × hi-fi plus
1⁄ × normal.
2
6.9.2
Mix-stereo of the output select function is generally used
for audio dubbing. In combination with the volume setting
of normal select, user control over amplitude and ratio is
offered for the auxiliary and the hi-fi signal as follows:
(1⁄4 × aux left + 1⁄4 × aux right) × volume left plus
(1⁄4 × hi-fi left + 1⁄4 × hi-fi right) × volume right.
INPUT MIX
The dub-mix mode is to be used in the (hi-fi) playback
mode. In the record mode, a signal loop from output to
input can be closed which may cause audio oscillation.
The auto-normal switching is not active during the dub-mix
mode. The hi-fi sound is muted when no hi-fi input signal
is detected; bit AUTN is not affected.
A new complete recording is made on the linear audio
track (see Fig.4). In the playback mode, only the linear
audio sound is used. In this way the hi-fi stereo quality is
lost, but total freedom in defining the new sound material
is an extra advantage. Furthermore, such recording is no
longer restricted to playback on hi-fi video recorders (with
an output mix option).

I2C-BUS PROTOCOL
7.1
Addresses and data bytes
Full control of the TDA9605H is accomplished via the 2-wire I2C-bus. Bus speeds up to 400 kbits/s can be used in
accordance with the I2C-bus fast-mode specification.
Seven data byte registers are available for programming the device (write mode) and one data byte register is available
for reading data from the device (read mode). The registers are addressable via eight subaddresses. Automatic
subaddress incrementing enables writing of successive data bytes in one transmission.
During power-up, the data byte registers and auto-calibration registers are reset to a default state by the use of a
Power-On Reset (POR) circuit. The reset signal is derived from an internally generated voltage supplied by VCC.

When during the playback mode no FM carrier is detected from tape, the normal audio signal on pin LININ is
automatically selected by the output select function.
For this auto-normal mode:
• The timing of the hi-fi carrier detection can be selected via bit DETH which defines the auto-normal release time:
– Fast mode: hi-fi detection delay is 1 to 2 HID control signal periods (for NTSC: 33 to 66 ms; for PAL: 40 to 80 ms)
– Slow mode: hi-fi detection delay is 7 to 8 HID control signal periods (for NTSC: 233 to 267 ms;
for PAL: 280 to 320 ms).
• The state of hi-fi detection and auto-normal can be monitored by I2C-bus control bit AUTN of the read byte.
• In case automatic selection of the normal audio signal is not required the normal input level control can be set to mute
(bits NIL3 to NIL0 of the select byte).

Bit NTSC selects between the NTSC and PAL (SECAM) system carrier frequencies for the CCO modulators or PLL
demodulators and the band-pass filters. FM carrier frequencies of 1.3 and 1.7 MHz are used for the NTSC system where
1.4 and 1.8 MHz are used for the PAL system. Different code settings for the auto-calibration circuit assure proper
calibration using the standard HID control signal frequency of 29.97 Hz for NTSC mode and 25 Hz for PAL mode. After
auto-calibration is completed bit NTSC enables instant switching between the NTSC and PAL system.

head signals from pins PBIN1 or PBIN2 to the internal node between the head amplifier and HF AGC circuit. The setting
of the playback amplification results in a selection of the hi-fi detection level (auto-normal function). The hi-fi detection
level indicated is the RMS value of the left channel carrier signal on pins PBIN1 and PBIN2.
The signal at the internal node can be monitored for testing purposes via pin ENVOUT using test 8 of the test mode.
It should be noted that the output level of test 8 shows 6 dB attenuation compared to the internal node level.

DESCRIPTION
HEAD AMPLIFIER RECORD CURRENT
A total of twelve settings of the recording current can be selected for the head amplifier record output pin RECOUT.
Bit HRL of the select byte selects between high and low current settings. The recording current is defined as the
peak-to-peak value of the current of the record output signal which includes both the left and right carrier signal.
The selected recording current is independent of the selected record mix ratio setting, but recording is disabled during
the record-mute mode as defined by the bits DOC, SHH and DETH or the control signal on pin RMHID.

POWER MUTING
The power mute function controls the mute switches on the
line and RF converter outputs. The power mute mode is
automatically activated via the Power-on reset function
during power-up of the supply voltage. During
power-down, the mute switches are activated
automatically by means of the auto-mute circuit which is
independent of the setting of bit MUTE. When setting
bit MUTE = 1 the output current on pins RFCOUT, LINEL,
LINER, DECL and DECR is limited to −1 mA for controlled
power-up response and the selected output signal is
muted (see Section 6.6).
Bit POR of the read byte is a logic AND function for
checking all I2C-bus register bits. Bit POR will read logic 1
when the I2C-bus register content equals the Power-on
reset default state and also when this state is set via the
I2C-bus control. Since a setting of bit PORR = 1 differs
from the Power-on reset default state, it forces a reset of
bit POR to logic 0 independent of other bit settings.
MODE
DESCRIPTION
Note
Setting bit PORR = 1 ensures a reset of bit POR of the
read byte to logic 0. In this way, a reading of logic 1 for
bit POR always indicates the occurrence of an actual
I2C-bus register Power-on reset and can not be caused
accidentally by other I2C-bus control bits. Bit PORR has no
control function but it is an unused bit, dedicated by name
to change the I2C-bus register content from the Power-on
reset state.

HEAD AMPLIFIER DISABLE
Bit HPD offers a special setting intended for use with some
of the built-in test modes and for support of particular
applications that do not require use of the integrated head
amplifier. By setting bit HPD = 1 the head amplifier
playback circuit is disabled. This mode enables direct input
signal to the HF AGC circuit via pin HMSW (AC coupled
via a 10 nF capacitor).

STANDBY SELECT
7.10.1
The TDA9605H is switched in the low-power active
standby mode by setting bit STBA = 1. Most circuits are
switched inactive for reducing power consumption.
However, the RF converter, line and decoder outputs
remain active in this mode and the direct audio selections
offered via the line select function and the decoder select
function remain available. The selected output signal is
muted during the active standby mode.
TDA9605H
CALIBRATION READY
The completion of calibration is signalled by changing
bit CALR from logic 0 to logic 1. Bit CALR remains logic 0
if for some reason a calibration can not be completed (i.e.
no HID control signal available or the hi-fi processing is in
the playback mode). Bit CALR will also return to logic 0 if
calibration is lost due to a Power-on reset situation.
Additional information about the calibration result is
available via bit CALE. Calibration is found correct if
bit CALR = 1 and bit CALE = 0.
The TDA9605H is switched in the minimum power passive
standby mode by setting bit STBP = 1. All circuits are
switched inactive to obtain minimum power consumption
except for the power mute circuit, the I2C-bus and the line
input reference buffer (i.e. the DC voltage on pins 1 to 11
remains active). When bit STBP = 1 a discharge current of
1 mA is active on pins RFCOUT, LINEL, LINER, DECL
and DECR.
Pin ENVOUT can also be used to monitor calibration
(see Section 6.5).
Table 35 Calibration ready (bit CALR)

Power muting ensures disturbance-free switching of the
line and RF converter outputs to and from the passive
standby mode. In the passive standby mode power muting
can be de-activated again to achieve minimum power
consumption. The calibration and I2C-bus registers are not
affected in the active standby or passive standby mode.

7.10.3
Detecting the occurrence of a Power-on reset by reading
bit POR requires a setting of bit PORR = 1 after power-up.
Bit POR is forced to logic 0 only by setting bit PORR = 1,
so this setting is independent of other I2C-bus bit settings.
CALIBRATION ERROR
An unreliable calibration result is indicated when reading
bit CALE = 1. The calibration result is not reliable when
during calibration the control signal on pin RMHID is
disturbed due to an external cause. Such a disturbance of
the HID control signal is detected when reading
bit CALE = 1. A new calibration should be started to
ensure proper calibration.
After calibration a Power-on reset occurrence is also
indicated by bit CALR = 0, because calibration will be lost.

Calibration is found correct when bit CALR = 1 and
bit CALE = 0.

POWER-ON RESET
An internal Power-on reset signal is generated at
power-up or during a power voltage dip. The I2C-bus data
bits and auto-calibration registers are reset to a
pre-defined state. When reading bit POR = 1, it indicates
that the internal data bits are found to be in the POR state
due to an actual Power-on reset or the I2C-bus control
settings.

Notes
1. Amplitude modulated single carrier signal of 60 mV (RMS) on pin HMSW; for playback mode HPD = 1. Control
bandwidth is defined as the modulation frequency at which the amplitude modulation is attenuated with 3 dB by the
HF AGC.
2. Sample-and-hold audio distortion is measured using a HID control signal of 500 Hz on pin RMHID, fmod = 10 kHz and
∆fFM = 50 kHz. Audio distortion is measured using a 3 kHz 4th-order low-pass filter. The measured value is corrected
with 24 dB in order to calculate the equivalent distortion for the standard NTSC 29.97 Hz HID control signal.
3. B = 20 Hz to 20 kHz, unweighted.

Test modes
Special test modes are implemented for testing, evaluation and measurement purposes. These test modes are available
when bit TEST = 1 and the test select function is enabled via five bits of the select byte (see Table 41). When selecting
test modes the normal input level setting is changed as defined by bits NIL3 to NIL0. Calibration may be lost when a not
listed test mode is selected.

Notes
1. This test can be used with a HIGH-level input signal by setting bit HPD = 1; test input signal applied to pin HMSW.
2. Auto-normal is activated (bit AUTN = 1) during the test, i.e. the playback audio signal is not available.
3. The output level on pin ENVOUT shows 6 dB attenuation compared to the internal signal of the head amplifier output.
4. This test connects internal signal lines between the noise reduction and (de-)modulator circuit. The signals found
here are not compensated for temperature or tolerance spread and therefore level measurements are only relative.
Absolute values are not an indication of the overall performance. Typical audio level of the test inputs and outputs is
approximately −6.5 dBV for the standard −8 dBV line level and 50 kHz FM deviation.
5. The expander test requires the auto-normal function to be set inactive; i.e. an FM carrier signal should be available.

If wave soldering is used the following conditions must be
observed for optimal results:
17 SOLDERING
17.1
Introduction to soldering surface mount
packages
• Use a double-wave soldering method comprising a
turbulent wave with high upward pressure followed by a
smooth laminar wave.
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).
• 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;
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.
17.2
TDA9605H
– 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.
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.
• 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,
infrared/convection heating in a conveyor type oven.
Throughput times (preheating, soldering and cooling) vary
between 100 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 dwell time is 4 seconds at 250 °C.
A mildly-activated flux will eliminate the need for removal
of corrosive residues in most applications.
Typical reflow peak temperatures range from
215 to 250 °C. The top-surface temperature of the
packages should preferable be kept below 230 °C.
17.3
17.4
Wave 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.
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.
1999 Apr 14
Manual soldering
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 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.
