Induction Soldering Copper Wires With IGBT High Frequency Heating Units
Objective Soldering two copper wires to pre-installed turrets on a copperย buss bar
Material Solder dipped copper/nickel buss bar, 2 tinned strandedย copper wires, brazing stick
Temperature 446 ยบF (230 ยบC)
Frequency 230 kHz
Equipment โข DW-UHF-6kW induction heating system, equipped with aย remote workhead containing one 1.2ฮผF capacitor.
โข An induction heating coil designed and developedย specifically for this application.
Process A four turn split helical coil is used to solder the buss barย assembly. The 2 copper wires are applied to the turrets andย power is applied for 30 seconds. The brazing stick is fed byย hand to the heated parts and the braze flows evenly, creatingย the joint.
Results/Benefits Induction heating provides:
โข Reduced solder time
โข Even distribution of heating
โข Joint to joint consistency
