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 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 โ€ข DW-UHF-6kW induction heating system, equipped with aย remote workhead containing one 1.2ฮผF capacitor.
โ€ข 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:
โ€ข Reduced solder time
โ€ข Even distribution of heating
โ€ข Joint to joint consistency

Induction Soldering Brass To Copper

Induction Soldering Brass To Copper With IGBT High Frequency Heating Equipment

Objective To heat brass and copper for soldering application on medicalย equipment
Material Brass ring, brass and copper pieces 5.11โ€ (130mm) long, 4.3โ€ย (110mm) OD & 0.3โ€ (7mm) at thickest point and solder rings
Temperature 392 ยบF (200 ยบC)
Frequency 306 kHz
Equipment โ€ข DW-UHF-10ย kW induction heating system, equipped with aย remote workhead containing two 0.33ฮผF capacitors for aย total of 0.66ฮผF
โ€ข An induction heating coil designed and developedย specifically for this application.
Process This process is completed in two steps that use a 3 turn helicalย coil. The first process is to solder the brass ring to the copperย piece which takes 85 seconds. The second step is to solder aย large brass piece to the first assembly. This process takes 50ย seconds for a total process time of two minutes 15 seconds.
Results/Benefits Induction heating provides:
โ€ข Hands-free heating that involves no operator skill forย manufacturing
โ€ข Even distribution of heating
โ€ข Faster process time, current process takes 5 minutes
โ€ข Consistency by using solder rings

Induction Soldering Copper Tap

Induction Soldering Copper Tapย 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.ย Lead free solder material (higher melting temperature thanย regular solder.)
Temperature 500 ยบF for 1.25 seconds
Frequency 286 kHz
Equipment DW-UHF-4.5ย kW, 150-400 kHz solid state induction heatingย system equipped with a remote heat station containing one 1.2ย ฮผF capacitor and a specially-designed work coil..
A multi-turn helical coil about 3/16 inch internal diameter madeย out of 1/16 inch diameter tubing.
Process Solder wire is fed onto speaker tab area using an automaticย wire feeder. It is then heated to re-flow the solder.
Results/Benefits With an efficient coil design induction heating easily reachesย the desired reflow temperature in a very short amount of time.
