Induction Soldering Aluminum Housing With IGBT High Frequency Soldering Units
Objective Heat an aluminum spotlight housing to solder an LEDย assembly to the inside base
Material LED housing with copper plug, aluminum spotlight housing 5โย (127mm) dia at top, 1.25โ (31.75mm) dia at base, temperatureย sensing paint
Temperature 500 ยบF (260 ยบC)
Frequency 45 kHz
Equipment โข DW-UHF-45kW induction heating system, equipped with aย remote workhead containing one 1.0ฮผF capacitor.
โข An induction heating coil designed and developedย specifically for this application.
Process A multi turn pancake coil is used to heat the bottom of theย aluminum spotlight housing. The LED housing was notย available so this application is done with temperature sensingย paint to determine the feasibility. The temperature sensingย paint is applied where the LED housing sits in the center of the
spotlight housing. The base of the housing reaches 500 ยบFย (260 ยบC) in 30 seconds.
Results/Benefits Induction heating provides:
โข Hands-free heating that involves no operator skill forย manufacturing
โข Faster production times, more energy efficient
โข Consistent, repeatable results
โข Even distribution of heating
