J-F, we've worked some at Compunetics with white. Contact me off-line and I can relay you to the engineer with most experience.

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!
