In attempting to work with what the world understands I want to mark my circuit boards in compliance with IPC/JEDEC J-STD-609. What marking systems are popular, effective, easy, non-conductive and won't dissolve in dielectric oil (mineral oil)? Kapton labels are common on many computer boards. Laser etch is great on high production runs. Manually scratched marks works for onesie-twosie assembly. Is white non-conductive epoxy ink stamped onto the board a viable solution? If so, can someone point me at a manufacturer or product? Thanks in advance.
