     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!
