Induction Soldering Brass Connector In Solar Panel With IGBT Induction Heater
Objective Solder three brass connectors one at a time in a solar panelĀ junction box without affecting the components in the junctionĀ box
Material Solar panel junction box, brass connectors, solder wire
Temperature 700 ĀŗF (371 ĀŗC)
Frequency 344 kHz
Equipment ā¢ DW-UHF-6Ā kW induction heating system, equipped with aĀ remote workhead containing one 1.0 Ī¼F capacitor.
ā¢ An induction heating coil designed and developedĀ specifically for this application.
Process A three turn oval shaped helical coil is used to heat theĀ connectors. A piece of solder wire is placed onto the joint areaĀ and each joint is heated separately for 5 seconds to solder theĀ connector. The total process time is 15 seconds for the threeĀ joints.
Results/Benefits Induction heating provides:
ā¢ Pinpoint accuracy deliver heating only to joint; does notĀ affect surrounding components
ā¢ Localized heat produces neat and clean joints
ā¢ Produces high quality, repeatable results
ā¢ Even distribution of heating
