About Induction Heating

Induction heating is a fast, efficient, precise and repeatable non-contact method for heating metals or other electrically-conductive materials. The material may be a metal such as steel, copper, aluminum, brass or it can be a semiconductor such as carbon, graphite or silicon carbide. To heat non-conductive materials such as plastics or glass, induction is used to heat an electrically-conductive susceptor, typically graphite, which then transfers the heat to the non-conducting material.

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

 
Ambrell Expertise:
  • Induction soldering equipment solves many of the application challenges.
  • Cleanliness of the solder joint surfaces is critical.
  • Both metal surfaces that are to be solder-joined must 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
