Soldering with induction heating is the process of joining metals by means of alloys that melt between 350ºF-700ºF. The strength of the joint depends on the chemical composition and cleanliness of the surfaces to be joined.

Soldering produces liquid- and gas-tight joints quickly and at low cost. Most soldering applications are carried out in air, with the flux acting as a barrier to surface oxidation and interaction with the atmosphere. It is a convenient and economical way to produce joints when more complex joining machines are not available or cost-effective.

Flux is applied first to the bonding surfaces and then heat is applied to the joint area. The temperature required is just above the melting point of the solder. The solder is allowed to flow in the joint. After reflow, the solder is allowed to cool naturally and re-solidify.

Metal: Iron, nickel, copper, lead, tin, zinc, aluminum
Solder: Generally lead and tin alloys·
Flux: Necessary to rid the surface of the metals to be joined of oxides, to promote wetting and obtain intimate contact between the solder and base metal. There are different forms of flux: corrosive, intermediate and non-corrosive. Corrosive (Acid) flux cleans the surface well and is good for copper, low carbon steel, brass and bronze soldering. However, it is difficult to clean off after the process. Intermediate fluxes contain organic compounds and decompose at soldering temperatures. They are suitable for all materials that are solderable with mild fluxes. Non-corrosive fluxes are rosin-based. They are a good choice for electronic and critical soldering applications.
Heat source: fast, precise induction heating is best.

induction soldering from Ambrell

Ambrell's induction heating equipment is very well suited for soldering applications in a production environment. Heat is applied to specific regions of a solder joint in a very controlled and precise manner. Induction soldering is well suited for production line applications (like fiber optic ferrule assemby) because of low time-to-temperature, high levels of repeatability and non-contact, clean heating.

Induction soldering system output power ranges from 1 to 20 kW, depending on part and process requirements.
