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.

Tin antimony mp = 236-240C 80Au / 20SN mp = 280C sn25 Ag10 sb = 365C There are very few high temperature service alloys. how about filling a 1400lb pot with 80% Gold! What is the application?

if a solder has over 85% lead its classed as RoHS complient because its difficult to achive the same melting point with anything else (298degrees). a few other alloys with a similar range are ; % % 266E266 82.6 Cd 17.4 Zn 271MP 100 Bi 280E2
