Solderability Testing

Solderability

Solderability testing can be performed on solder pads or component terminations.

A wetting balance is used to measure the forces involved when a globule of molten solder wets the sample surface. This gives a measure of the quality of the surface in terms of ability to be wet by solder.

Two values are normally quoted: wetting force and wetting time.

Common applications:

  • Quality assessment or control for component batches
  • Assessing old component batches for suitability for use in production
  • Assessing performance and ranking of lead platting, surface finishes, fluxes and alloys
