Silver Epoxy and CEM3 | 26 August, 1998

Does anyone have any experience they are willing to share on Ag epoxy used as a copper through hole plating replacement? Was CEM3 used? What are the limitations? Thanks, Steve

Hope you guys (Intel) aren't going to do that to us in public yet as I just got my main board and other components to work with some predictability (not Intel's of course). What the heck, yes I've been there and done that with less than spectacular results. However, on a limited basis, it works. Go for it as you will take us where we've never been in production. Don't you always?

Was CEM3 used? | What are the limitations? | Thanks, | Steve I have used silver epoxy extensively for conductive bonding applications such as attachment of a ground to ferrite cores, attachment of leads to bare (uncoated) high voltage capacitors, and similar applications. It has worked well for these purposes. I MIGHT use it for a two sided PWB through hole repair for a home project or in-house test equipment board, but would not even consider it for multi-layer boards. I would never consider it for production purposes. Pete Sorenson
