Induction Soldering Brass Connector In Solar Panel With IGBT Induction Heater
Objective Solder three brass connectors one at a time in a solar panelย junction box without affecting the components in the junctionย box
Material Solar panel junction box, brass connectors, solder wire
Temperature 700 ยบF (371 ยบC)
Frequency 344 kHz
Equipment โข DW-UHF-6ย kW induction heating system, equipped with aย remote workhead containing one 1.0 ฮผF capacitor.
โข An induction heating coil designed and developedย specifically for this application.
Process A three turn oval shaped helical coil is used to heat theย connectors. A piece of solder wire is placed onto the joint areaย and each joint is heated separately for 5 seconds to solder theย connector. The total process time is 15 seconds for the threeย joints.
Results/Benefits Induction heating provides:
โข Pinpoint accuracy deliver heating only to joint; does notย affect surrounding components
โข Localized heat produces neat and clean joints
โข Produces high quality, repeatable results
โข Even distribution of heating
