Fellow Technetters,
On some of our bare boards before build, with normal board handling,
(before ANY processing has been done) we are noticing that the solder
mask is flaking off. This condition is no longer there after wave
solder. Our impression is that the mask is not fully cured. Are there
other things that could cause this (contamination)?
Is there a test that we can perform on the bare boards to prove/test
this?
Any thoughts would be appreciated!!
Thanx in advance, group!
