Hello I am looking for some documents about solderability tests for BGA s with eutectik balls. Can anybody help me in this subject? We think that the BGA- Balls were touched by fingers and the solderiability is significant reduced. How can we analyse the component for fingerprints? We are thinking of looking for NaCl. Has anybody another idea?
