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.
