There is a lot to wade through in this post, and you will probably want to skip past the heat sink tests, but he offers a thorough analysis of his subject.
Thanks for posting on this topic. There has been a lot of discussion and opinion on this in the past. I'm looking forward to learning more about it.
I use to promote the use of "Copper Antiseize Thread Lubricant" (VersaChem), thinking the copper would enhance conductivity. gstallons set me straight on this years ago: no, its a grease and doesn't conduct.
Then, I discovered the older it gets, the harder the "copper" component becomes. It just turns into a nasty, solidified mess that's hard to clean up. I still use it on threads, but not on electrical connections anymore.
@Scud: Great news on the relay success!!
