A Test Methodology for Copper Dissolution in Lead-Free Alloys

Lead-free selective soldering can result in extended times at high temperatures,which in turn can result in excessive dissolution of exposed copper,such as plated through holes. This phenomenon .. read more

Perspectives on Repaired Lead-Free Solder Joints

The use of lead-free (LF) solders as a replacement for traditional tin-lead (SnPb) solders in military and high reliability applications has a number of technical challenges unique to the indus .. read more

Conquer Tombstoning in Lead-Free Soldering

Tombstoning of SnAgCu is affected by the solder composition. At vapor phase soldering,both wetting force and wetting time at a temperature well above the melting point have no correlation with .. read more
