Hi Rudy, > If you have pure Tin plated pins, electrically in contact with solder, > They better be in electrical contact, otherwise what's the point? > this is VERY prone to corrosion, as you will be getting galvanically (does > that > word exist?) > Sure, you just created it. Now we tell the rest of the world. > corrosion. Tin is much more electropositive than solder, and > therefore will corrode readily when in contact with solder. > Everything's a battery, first heaters in plating tanks and now MillMax pins. > Does this help? > Yeah, your making some rusty gears turn in my head. <re-entering grad student mode> (Doesn't anybody have a spare CVD or MBE they want me to make chips with? Group III-V, II-VI or plain old silicon would do just fine.) Looks like I get to play scientist, do some experiments and not have to write a DARPA grant for it! Hans ~~~~~~~~ Hans M.
