Bridging at Reflow, What is the Cause and Can it be Eliminated?

by: Robert Dervaes, V.P. Technology; FCT Assembly

Surface mount technology (SMT) started in the 1960s and became more common in the 1980s. It is the dominant technology in use today. Through-hole technology is still in use, and will be for the foreseeable future, but the drive towards miniaturization of components is only possible with SMT and surface mount devices (SMD). While smaller SMD sizes allow for smaller, and more powerful, assemblies, they present many more challenges during the SMT assembly process.
