Note: Soldering two connectors simultaneously to ground plate

Objective:

Soldering two connectors simultaneously to a tin plated copper ground plate

End Product:

ground plate

Equipment:

Ambrell 5 kW induction heating system, equipped with a remote workhead containing two  1.0μF capacitors for a total of 0.50μF An induction heating coil designed and developed specifically for this application.

Materials:

Tin plated copper ground plate 4 inx 1.75 in (101.6mm x 44.45mm), 2 connectors, one with12 pins & one with 4 pins and 60/40 solder

Temperature:

650 °F (343 °C)

Frequency:

321 kHz

Testing:

A three-turn helical coil is used to heat both sets of pins simultaneously. Power is applied for less than 20 seconds causing the solder to flow. A solder stick can be used but solder preforms work better.

Benefits:

Induction heating provides:

  • Non-contact heat

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

  • Even distribution of heating
