17. Soldering

17.1 Introduction to soldering through-hole mount packages

This text gives a brief insight to wave, dip and manual soldering. 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).
Wave soldering is the preferred method for mounting of through-hole mount IC
packages on a printed-circuit board.

17.2 Soldering by dipping or by solder wave

The maximum permissible temperature of the solder is 260 °C; solder at this
temperature must not be in contact with the joints 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 (Tstg(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.

17.3 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 °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.

17.4 Package related soldering information

[1] For SDIP packages, the longitudinal axis must be parallel to the transport direction of the
printed-circuit board.
