Induction Soldering copper

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 Power of 6kW, 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.
