Yes we hit this problem several years ago, hence my qualifier of non-hydroscopic of which there are various options........ -----Original Message----- From: Linstrom, John (IndSys, GEFanuc, CDI) [mailto:john.linst...@gefgreenville.ge.com] Sent: Wednesday, September 01, 1999 3:20 PM To: 'James, Chris' Cc: 'emc-p...@ieee.org' Subject: RE: "hard anodized" process to insulate metal chassis parts
Maybe a slip of the fingers... We recently got bit on the fishpaper insulation. Fishpaper absorbs moisture; better to call it plastic, or mylar, etc. than to leave a possible suggestion that fishpaper is any good for this application.

It is also fairly easy to compromise, so in a mechanical assembly you would be hard pressed to know how good the insulator was or how long it would remain so after the rigours of use (vibration etc.). Better to stick with SIL pad type materials or non-hydroscopic "Fish card" type insulators.

The related spec describing this process is MIL- A-8625F. Please advise at your earliest convenience.
