We recently experienced soldermask peeling after wave from
three different Fabricators all within 2 weeks. Subsequently
we took sample lots of each Fabricator and performed a
pre-wave and post-wave tape test. In all lots the boards
passed pre-wave tape test but had a 10-25% failure post wave.
What can cause this phenomena? Does the weather change have
anything to do with soldermask application and durability?
