AuSn solder alloy



AuSn solder alloy | 26 December, 2003

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.
