try Elisabeth Soderstrom or Margaret Nylen at IM, the Swedish Institute for Metal Research, they have tons of material about solders. Good Luck./Ingemar

Subject: Phase transistions in solder joints


Hi,

Does anyone know if there occurs any transitions that weaken the solder joint if the working temperature is between 80-90 C. The solder is a SnPb 63/37. Maybe the question should be put like this; is there a build up of weak intermetallic phases at about 80C?

Kind regards,

Sophia Johansson
