Soldering connector to wire harness

Objective

Heat stainless steel connector for soldering application in automotive wire harness manufacturing

End Product

wire harness

Equipment

Ambrell 4.2 kW induction heating system, equipped with a remote workhead containing one 1 μF capacitor.

An induction heating coil designed and developed specifically for this application

Materials

Stainless steel connector 1.57” (40mm) long, 0.6” (15mm) OD & 0.4” (10mm) thick. Lead free solder

Temperature

392 ºF (200 ºC)

Frequency

352 kHz

Testing

A two-turn channel coil is used for soldering the connector to the wire harness. The stainless steel connector and wire harness are placed in the coil for 20 seconds for the solder to fill just the top of the connector.

Benefits

Induction heating provides:

• By precisely heating the metal, the plastic shroud is not directly heated 

• Reduced production cost

• Faster process time,  reduced production cost

• Hands-free heating that involves no operator skill for manufacturing

• Even distribution of heating
