.int [log in to unmask]

 For a good paper see http://www.amp.com/product/articles/dd68_1.html
 on the web, Per the Tin Commandments:
 "Mating tin-plated contacts to gold-plated contacts is not recommended."

 I have this situation on my home computer and sure enuf, after a yaer
 I had to re-seat the sims!

 Does anyone out there have experience/knowledge of mating gold-plate edge
 contacts (on SIMMS - so dry contacts) with tinned connectors. Is it a no-no
 from a long-term reliability point of view?

 We have a first source with tinned edge contacts (matching the connector) and
 are lokking at a gold-plate second source.
