I have a board, 4 spacers needed to be soldered on the board first with the normal 62Sn37Pb alloy. Then, capacitors are manually soldered on the boards. The density of the board is quite high. If we wave soldered capacitors first, there will be no p

hi, I wondering if anyone have any information on intermetallic growth in 80Au20Sn solder alloy. I have read that it has high reliability. Which bring an important question to my mind. What about Gold embrittlement ? Bye Indy

You're thinking correctly. 80Au20Sn is incompatible with: * Sn/Pb * In/Sn * Sn/Pb/In * Sn/Pb/Bi Contact your solder supplier to obtain pictures of IMC.
