摘要
Significant manufacturing cost reductions can be realized with lower-temperature surface mount processing by increasing yields and using less expensive components and boards. A lower-melting-point solder alloy (nominal composition Sn-41.75Pb-8Bi-0.5Ag) has been developed that enables significant reductions in peak reflow temperatures during surface-mount assembly. The solder alloy is compatible with standard Pb-Sn surface finishes, melts within the temperature range of similar to 166-172 degrees C, and has promising mechanical properties.
