What is Induction Soldering?

Many soldering applications are now carried out using induction heating power units and handling systems. Typical components processed are capacitors, electrical contacts, special drills, electrical contacts and water heater elements.

Induction Soldering falls into two broad categories. Soft soldering typically utilising temperatures up to 300°c, and silver soldering at temperatures in the region of 650°c - 700°c.

Power units are available from 3kW up to 500kW but generally most soldering applications use 12kW to 30kW units from our Ultratec range.

In high volume production environments it is common to combine the induction heater with a component handling system of some kind. Dependant on the level of throughput and component geometry these can be either manual, fully automated or in some cases a combination. These systems include inline conveyor system, rotary tables, double shuttles, pick and place systems and many other "tailor made" solutions. Inductelec is unique in being able to offer the complete turnkey solution from concept and design to manufacture of all system elements under one roof.

The main advantages of induction heating for soldering are:-

• Repeatability
• Lower distortion
• Reduced discolouration or oxidisation
• Rapid heat rates
• Accurately focused heat affected zone
• Extremely well controlled heat input and temperature
• No pressurised gas systems and associated H&S considerations
• Better working conditions
• Improved operator safety
• Highly efficient energy conversion

Many of the advantages above are due to the ability to accurately control all the major parameters i.e. time, power and temperature, this can be achieved either internally or from a peripheral system via our CAN buss interface.

Most common metals and alloys which can be soldered by other methods can be joined using induction. Dissimilar metals can be joined using the technique, however, special consideration needs to be given in situations where a magnetic metal is joined to a non-magnetic material but normally these differences can be overcome by coil/inductor design.

Because most systems are automatic/semi-automatic, operator skill is reduced in comparison to torch brazing or other conventional methods. By Utilising our Ultratec power unit and our purpose designed safe-braze work-head coil voltages are reduced and operator safety is assured.

For precision applications a range of temperature control options are available normally utilising a non contact type infra red pyrometer. These systems easily interface to the Ultratec via the dedicated CAN buss interface.
