Induction Soldering

Heating up the joints to be soldered without establishing contact to a heat source is the major benefit of induction soldering systems. In an inductive loop, high-frequency alternating current is used to generate an electromagnetic field. Based on Faraday's induction principle, if metal parts are immersed in this field, current is induced in these parts. It is this current which, because of the inner resistance of the metals, leads to the metal parts to be heated up. But that the induced current can heat up the metal parts to the required temperature, they must be of a critical mass; thin layers, for example, cannot be heated by induction. Another significant advantage is that only and exclusively metal components are being heated. Plastic parts will not heat up directly, but only indirectly through thermal conduction. Depending on the design of the inductive coil and the generator power output, large or heavy parts to be joined can be effectively heated up in a relatively short time.
