FROM: BRUCE HOUGHTON 27/552/844/TOR Phone (416) 448-5701 Tie 778-5701 Subject: Re: Tin/tin vs. Tin/gold sockets Tom, I suggest contacting the various connector suppliers, such as AMP Burndy etc and get their input on your request. I expect they will highly recommend NOT mixing dissimilar metals. The tin will oxide and crate an increasingly higher resistance, which will at some point start to cause noise problems. The two metals can also create an electrical potential (battery) across the joint which can also affect the electrical signals. Bruce Houghton Celestica, Inc.
