The Solderability test method provides optional conditions for preconditioning and soldering for the purpose of assessing the solderability of device package terminations. It provides procedures for dip & look solderability testing of through hole, axial and surface mount devices and a surface mount process simulation test for surface mount packages.
Solderability testing provides a means of determining the solderability of device package terminations that are intended to be joined to another surface using SnPb or Pb-free solder. The procedure, considered to be destructive, will test whether the packaging materials and processes used during the manufacturing operations produce a component that can be successfully soldered in the next level assembly.
There are two methods of solderability testing. Method 1 is known as “dip and look” which is for leaded and leadless terminations. This method includes pre-conditioning if applicable, the application of flux, and the immersion of the terminations into molten solder. Method 2 is a Surface Mount Process Simulation test.
The purpose of this test method is to provide a means of determining the solderability of the device package terminations that are intended to be joined to another surface using lead- (Pb-) containing or Pb-free solder for the attachment.
