Subject: [TN] White solder mask discoloration

Hi Technetters,

 

Does anyone have experience with white solder mask?  Any chances of success
passing these through reflow without discoloration?

 

We had a bunch of them sent to our CM and they all came back with a yellow
to brown discoloration.  I believe there are different types of solder masks
out there but is there some standard regarding their capacity to resist
heat?  The process used it RoHS.

 

Thanks in advance!
