Induction Soldering Steel to Brass

Objective
Heat an assembly of small, gold-plated steel connectors to a brass block.
Approx. 1/8” (3.2mm) diameter gold-plated steel connectors,
1”(25.4mm) square x 1/4” thick brass block ,600°F(315.6ºC),240 kHz
Temperature,Frequency,Equipment
6 kW induction heating system equipped with aremote workhead.
An induction heating coil designed and developed specifically for this application.
Process
A two-turn helical coil is used to provide uniform heat to parts
assembly. Solder paste and flux are applied to the joint area and power is applied for 20 seconds to solder the parts. Proper fixturing is needed to hold the parts in position.
