If you're wondering, "why should I use induction soldering?" then you've come to the right place. Induction soldering is an induction process in which two separate pieces are fused together using a filler metal or other material. The filler metal varies depending on the other components being joined, but the most common fillers for induction soldering include alloys such as tin-silver, tin-zinc, and tin-lead.

An integrator supplying a manufacturer of circuit boards was looking to use induction heating for a soldering application that involved tiny parts. The application involved heating a coaxial wire and a metal frame for soldering. Given the small size of the parts, an EASYHEAT^TM 1.2 kW, 150-400 kHz induction heating system equipped with a remote workhead was more than adequate for the application.

This application involved soldering copper wires from the transformer to the steel pins. We first needed to determine the cycle time that would get sufficient heat into the pins and not melt the coating on the surface. We started our testing with a 2 kW EASYHEAT induction heating system, but found it delivered more power than was necessary, so we used a 1 kW EASYHEAT instead.
