In a properly wetted joining system, with tin/lead solder as the filler and copper as the base metals, a layer of intermetallic compounds is usually found at the interface of these two metals. This layer, mainly copper and tin, has profound effects o

A novel and direct method to measure the stress-strain properties of surface mount solder joints is proposed in this paper. The specimen used in the experiments is a quad flat pack (QFP)-solder-printed circuit board (PCB) assembly and the fabrication

A direct method to measure the fatigue life of surface mount solder joints is proposed. This approach makes use of a quad flat pack (QFP) solder-printed circuit board (PCB) assembly as a shear specimen. After the assembly and thermal stress screening
