For a few thousend boards, I would look into some automation. In order to get the components off the boards you could run the boards through the reflow oven with the cooling fans turned off. When the boards come out of the oven the solder is still l

I too would be amazed if Chris is wave soldering this socket and component. It's possible that these devices are on the primary side.

Hey Bud. Allow me to 'turn' your point about 'grain structure' just a bit. Fast cooling rates / coarse grain structures was a bit of red herring in the early 80's. Faster cooling DOES produce finer grained solder connections. Accelerated testing of
