Notes to application information
1. The interference suppression and noise feedback control thresholds can be determined by R13 or a capacitive
voltage divider at the input of the high-pass filter and they are defined by the following formulae:
V
= (1 + R13/RS) × V
i(tr)
Vni = (1 + R13/RS) × V
in which RS= 2 kΩ;
i(tr)O
in which RS= 2 kΩ.
niO
2. The suppression pulse duration is determined by C11 = 2,2 nF and R11 = 6,8 kΩ.
3. The characteristic of the noise feedback control is determined by R12 (and R10).
4. The feedback control of the interference suppression threshold at higher repetition frequencies is determined by R10
(and R12).
5. The 19 kHz generator can be adjusted with R
7-16
(and R
). Adjustment is not required if components with small
7-8
tolerances are used e.g. ∆R < 1% and ∆C < 2%.
6. Measuring conditions:
The peak output noise voltage (V
µs (R = 5 kΩ, C = 10 nF); the reference value of 0 dB is V
, CCITT filter) shall be measured at the output with a de-emphazing time T = 50
no m
with the 19 kHz generator short-circuited (pin 7

grounded).

SOLDERING
Introduction
There is no soldering method that is ideal for all IC
packages. Wave soldering is often preferred when
through-hole and surface mounted components are mixed
on one printed-circuit board. However, wave soldering is
not always suitable for surface mounted ICs, or for
printed-circuits with high population densities. In these
situations reflow soldering is often used.
This text gives a very brief insight to a complex technology.
A more in-depth account of soldering ICs can be found in
“IC Package Databook”

S
The maximum permissible temperature of the solder is
260 °C; solder at this temperature must not be in contact
with the joint for more than 5 seconds. The total contact
time of successive solder waves must not exceed
5 seconds.
The device may be mounted up to the seating plane, but
the temperature of the plastic body must not exceed the
specified maximum storage temperature (T
printed-circuit board has been pre-heated, forced cooling
may be necessary immediately after soldering to keep the
temperature within the permissible limit.

EPAIRING SOLDERED JOINTS
Apply a low voltage soldering iron (less than 24 V) to the
lead(s) of the package, below the seating plane or not
more than 2 mm above it. If the temperature of the
soldering iron bit is less than 300 °C it may remain in
contact for up to 10 seconds. If the bit temperature is
between 300 and 400 °C, contact may be up to 5 seconds.

). If the

Several techniques exist for reflowing; for example,
thermal conduction by heated belt. Dwell times vary
between 50 and 300 seconds depending on heating
method. Typical reflow temperatures range from
215 to 250 °C.
Preheating is necessary to dry the paste and evaporate
the binding agent. Preheating duration: 45 minutes at
45 °C.
AVE SOLDERING
W
Wave soldering techniques can be used for all SO
packages if the following conditions are observed:
• A double-wave (a turbulent wave with high upward
pressure followed by a smooth laminar wave) soldering
technique should be used.
• The longitudinal axis of the package footprint must be
parallel to the solder flow.
• The package footprint must incorporate solder thieves at
the downstream end.
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.
Maximum permissible solder temperature is 260 °C, and
maximum duration of package immersion in solder is
10 seconds, if cooled to less than 150 °C within
6 seconds. 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.
EPAIRING SOLDERED JOINTS
R
Fix the component by first soldering two diagonally-
opposite end leads. Use only a low voltage soldering iron
(less than 24 V) 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.
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.
