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

Objective Heat connector assemblies for soldering
Material Device assembly
Tin plated brass terminals Solder paste
Temperature 500°F (260°C) 5-7 seconds
Frequency 360 kHz
Equipment DW-UHF-6kW induction heating system equipped with a remote heat station, containing two 0.66 μF capacitor. An induction heating coil designed and developed specifically for this application.
Process A single turn helical coil is used to heat the solder paste. The connectors are placed inside the induction heating coil and RF power is applied for 5-7 seconds until the connector heats.
Solder paste is applied to the joint in two ways, stick-fed or manually.
Results/Benefits • Compared to using a manual soldering iron, induction heating precisely applies heat to for higher quality solder joints
• This is ideal for integrating with an automated system. By stick- feeding the solder more aesthetically pleasing parts are produced.
