Note: Soldering a copper tab on a speaker ring
Objective:
Heat copper tab until the solder reflows.
End Product:
audio speaker
Equipment:
Ambrell 1.2 kW, 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.
Materials:
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 *F (260 *C)
Frequency:
286 kHz
Testing:
Solder wire is fed onto speaker tab area using an automatic wire feeder. It is then heated to re-flow the solder
Benefits:
With an efficient coil design induction heating easily reaches the desired reflow temperature in a very short amount of time.
