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. 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.
Repairing 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.
