Selective Soldering Recommendations
Selective dip soldering is a variation of reflow soldering. In this method, the printed circuit board with through-hole components to be
soldered is preheated and transported over the solder bath as in normal flow soldering without touching the solder. When the board is
over the bath, it is stopped and pre-designed solder pots are lifted from the bath with molten solder only at the places of the selected
components, and pressed against the lower surface of the board to solder the components.
The temperature profile for selective soldering is similar to the double wave flow soldering outlined in this document, however, instead
of two baths, there is only one bath with a time from 3 to 10 seconds. In selective soldering, the risk of overheating is greater than
in double wave flow soldering, and great care must be taken so that the parts are not overheated.
