Hello Lou...
At my old company, we used a company called GTI
(http://www.graphic-tech.com/html/electronic.html) for our PCB labeling
needs. These labels contained model designation, serial number, and a
barcode, and were exposed to the wave solder and an aqueous wash with a dry
cycle. As long as the raw boards were received contaminant-free from our
supplier, the labels performed flawlessly.

Subject: [TN] Labeling of PC boards
TechNetters,
Here is a low-tech question. I have a customer who has been calling for
printing of board numbers, revs, serial numbers using epoxy ink. This
operation is time consuming, messy, prone to human error. We've been
talking about using computer-printed paper labels instead of epoxy ink. The
environment these boards go into is not particularly benign. Some are used
in train cars. They get an acrylic conformal coating.
Has anyone had experience in the matter of label durability? Any test
methods to suggest? Thanks for any comments.
