Induction Soldering Copper Wires

Induction Soldering Copper Wires With IGBT High Frequency Heating Units

Objective Soldering two copper wires to pre-installed turrets on a copper buss bar
Material Solder dipped copper/nickel buss bar, 2 tinned stranded copper wires, brazing stick
Temperature 446 ºF (230 ºC)
Frequency 230 kHz
Equipment • DW-UHF-6kW induction heating system, equipped with a remote workhead containing one 1.2μF capacitor.
• An induction heating coil designed and developed specifically for this application.
Process A four turn split helical coil is used to solder the buss bar assembly. The 2 copper wires are applied to the turrets and power is applied for 30 seconds. The brazing stick is fed by hand to the heated parts and the braze flows evenly, creating the joint.
Results/Benefits Induction heating provides:
• Reduced solder time
• Even distribution of heating
• Joint to joint consistency

Induction Soldering Copper Tap

Induction Soldering Copper Tap on a Speaker Ring with IGBT Induction Heater

Objective Heat copper tab until the solder reflows.
Material Copper tab 0.25 X 0.25 inch square about 0.05 inches thick. Lead free solder material (higher melting temperature than regular solder.)
Temperature 500 ºF for 1.25 seconds
Frequency 286 kHz
Equipment DW-UHF-4.5 kW, 150-400 kHz solid state induction heating system equipped with a remote heat station containing one 1.2 μF capacitor and a specially-designed work coil..
A multi-turn helical coil about 3/16 inch internal diameter made out of 1/16 inch diameter tubing.
Process Solder wire is fed onto speaker tab area using an automatic wire feeder. It is then heated to re-flow the solder.
Results/Benefits With an efficient coil design induction heating easily reaches the desired reflow temperature in a very short amount of time.
