Good morning all,

This is a question regarding the repair of FR-4 after there has been a high voltage arc/burn.  In a recent failure we ground out all the burned material and "repaired" the board with 5 minute epoxy.  This is on a pancake connector for a 160kV x-ray tube.  I am of the opinion that 5 minute epoxy will soon fail as it does not have the same insulating characteristics as the base FR-4.

I see that Circuit Technology carries all sorts of repair materials/kits.  So, if you were to salvage a burnt circuit board that had to ship right away, what materials would you use?

Off line replies are accepted if you want to protect your sources or don't want to "advertise" on Technet.

Thanks in advance for your wealth of information,
