Impact of Pb-free Solder Alloy Mixing on Solder Joint Integrity Using BGAs
An investigation was conducted to assess the solder joint integrity (acceptable/nonacceptable) for three different solder alloys on ball grid arrays (BGAs) in a mixed metallurgy configuration as compared to a baseline SAC305 system. Thermal cycle testing using a -55 to +125 ºC range in accordance with the IPC-9701 specification was used.
