Induction Soldering Fuse Caps

Induction Soldering Fuse Caps With IGBT Induction Heating Units

Objective Soldering three fuse caps simultaneously to reflow lead free solder and make a joint between the fuse cap and fuse wire guide
Material Plated copper end caps 0.375” (9.5mm) OD x 0.375” (9.5mm) height, ceramic fuse tube 1.5” tall (38.1mm) , lead free solder preforms
Temperature 700 ºF (371 ºC)
Frequency 286 kHz
Equipment • DW-UHF-20 kW induction heating system, equipped with a remote workhead containing two 1.0μF capacitors for a total of 0.5μF
• An induction heating coil designed and developed specifically for this application.
Process A three position two turn helical coil is used to solder three fuse caps simultaneously. The fuse assemblies are placed in the coil and the heat is applied in three cycles at 3.5 seconds per cycle to reflow the solder. On the production line the bottom caps are soldered first. The fuses are filled with sand and without flipping the assembly the top cap is soldered.
Results/Benefits Induction heating provides:
• Consistent, repeatable results
• Precise & accurate heat application
• Hands-free heating that involves no operator skill for manufacturing
• Even distribution of heating

Induction Soldering Brass Connector

Induction Soldering Brass Connector In Solar Panel With IGBT Induction Heater

Objective Solder three brass connectors one at a time in a solar panel junction box without affecting the components in the junction box
Material Solar panel junction box, brass connectors, solder wire
Temperature 700 ºF (371 ºC)
Frequency 344 kHz
Equipment • DW-UHF-6 kW induction heating system, equipped with a remote workhead containing one 1.0 μF capacitor.
• An induction heating coil designed and developed specifically for this application.
Process A three turn oval shaped helical coil is used to heat the connectors. A piece of solder wire is placed onto the joint area and each joint is heated separately for 5 seconds to solder the connector. The total process time is 15 seconds for the three joints.
Results/Benefits Induction heating provides:
• Pinpoint accuracy deliver heating only to joint; does not affect surrounding components
• Localized heat produces neat and clean joints
• Produces high quality, repeatable results
• Even distribution of heating

Induction Soldering Copper Tap

Induction Soldering Copper Tap on a Speaker Ring with IGBT Induction Heater

Objective Heat copper tab until the solder reflows.
Material Copper tab 0.25 X 0.25 inch square about 0.05 inches thick. Lead free solder material (higher melting temperature than regular solder.)
Temperature 500 ºF for 1.25 seconds
Frequency 286 kHz
Equipment DW-UHF-4.5 kW, 150-400 kHz solid state induction heating system equipped with a remote heat station containing one 1.2 μF capacitor and a specially-designed work coil..
A multi-turn helical coil about 3/16 inch internal diameter made out of 1/16 inch diameter tubing.
Process Solder wire is fed onto speaker tab area using an automatic wire feeder. It is then heated to re-flow the solder.
Results/Benefits With an efficient coil design induction heating easily reaches the desired reflow temperature in a very short amount of time.
