Solderability Test

  • Posted by Manuel Padial Pérez
  • On March 28, 2020
  • 0
Solderability test refers to the process of evaluating the solderability of terminations (i.e., component leads, lugs, terminals, wires, etc.). which are normally joined by a soldering operation. The solderability determination is based on the ability of the terminations to be wetted by the molten solder after accelerated aging.
