发明名称 SHELF LIFE IMPROVEMENT OF ELECTROPLATED SOLDER
摘要 The coating of electroplated solder, applied in preparation for a solder reflow operation, has a short shelf life. The shelf life can be greatly extended, without raising the melting point or detracting from the bond strength, by electroplating a layer of bright tin over the coating of electroplated solder.
