Induction heating is very well suited for soldering applications. Heat is applied to precise regions of a part in a very controlled manner. Induction heating is well suited for production line applications (like fiber optic ferrule assembly) because of low time-to-temperature, high levels of repeatability and non-contact, clean heating.
Typical induction heating systems for soldering range from 1 to 40 kW.
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. Consult with our experts to determine the proper flux for your process
Heat source: fast, precise heating is best.
Low unit strength.
Little resistance to fatigue
Limited to service temperatures below 300ºF.
Cleanliness of the joint surfaces is critical.
Both metal surfaces that are to be joined need to come to temperature at the same time.
If the temperature is too high, a strong joint cannot be created.
Instead of stick-feeding the solder, use a paste or preform solder that is placed in the joint areas before heating
