Induction Soldering Aluminum Housing With IGBT High Frequency Soldering Units
Objective Heat an aluminum spotlight housing to solder an LEDĀ assembly to the inside base
Material LED housing with copper plug, aluminum spotlight housing 5āĀ (127mm) dia at top, 1.25ā (31.75mm) dia at base, temperatureĀ sensing paint
Temperature 500 ĀŗF (260 ĀŗC)
Frequency 45 kHz
Equipment ā¢ DW-UHF-45kW induction heating system, equipped with aĀ remote workhead containing one 1.0Ī¼F capacitor.
ā¢ An induction heating coil designed and developedĀ specifically for this application.
Process A multi turn pancake coil is used to heat the bottom of theĀ aluminum spotlight housing. The LED housing was notĀ available so this application is done with temperature sensingĀ paint to determine the feasibility. The temperature sensingĀ paint is applied where the LED housing sits in the center of the
spotlight housing. The base of the housing reaches 500 ĀŗFĀ (260 ĀŗC) in 30 seconds.
Results/Benefits Induction heating provides:
ā¢ Hands-free heating that involves no operator skill forĀ manufacturing
ā¢ Faster production times, more energy efficient
ā¢ Consistent, repeatable results
ā¢ Even distribution of heating
