Hi All,

We had an issue last month. The legend marking on the board was white in
color. As the assembeled boards were passed thru reflow ,we observed that
the color changes to pink in color.in random boards. could not despatch the
boards. The process and the pcb were LF. The supplier confirmed problem with
the inks.

Thanx
Badri

Subject: [TN] Silkscreen Outgassing?


Hi All!

We asked one of our customer today why they didn't have silkscreened
reference designators on their PCB's (there's plenty of room on the
board BTW), and they said they were told by their PCB vendor that it
would outgas?!?? Has anyone ever heard that before? They are downhole
boards BTW...

I've never heard that before. I would think that if you were worried
about the silkscreen outgassing, then you would have the same worry
about the soldermask too...or am I wrong?
