Wave soldering is the preferred method for mounting of
through-hole mount IC packages on a printed-circuit
board.
Soldering by dipping or by solder wave
The maximum permissible temperature of the solder is
260
掳C;
solder at this temperature must not be in contact
with the joints for more than 5 seconds.
TDA8357J
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
stg(max)
). If the
printed-circuit board has been pre-heated, forced cooling
may be necessary immediately after soldering to keep the
temperature within the permissible limit.
Manual soldering
Apply the soldering iron (24 V or less) to the lead(s) of the
package, either below the seating plane or not more than
2 mm above it. If the temperature of the soldering iron bit
is less than 300
掳C
it may remain in contact for up to
10 seconds. If the bit temperature is between
300 and 400
掳C,
contact may be up to 5 seconds.

Limiting values
Limiting values given are in accordance with the Absolute Maximum Rating System (IEC 134). Stress above one or
more of the limiting values may cause permanent damage to the device. These are stress ratings only and operation
of the device at these or at any other conditions above those given in the Characteristics sections of this speci铿乧ation
is not implied. Exposure to limiting values for extended periods may affect device reliability.
