Soldering Ferrule and Module Assembly

To heat ferrule and module assemblies for a soldering application in the fiber optics industry.

Sealing a Kovar tube

The client was using a torch, and operator error was slowing the heating. The repeatability of induction enables improved throughput while in this process it is a more efficient heating method than torch heating, also reducing scrap

Hermetic sealing: SS rods & glass preforms

Induction melting provides hands-free heating that involves no operator skill for manufacturing, amounts of glass are precisely controlled by the glass preforms and even flow of glass creates aesthetically pleasing bond.

Heating a Kovar Ferrule for Glass Soldering

The solder formed a relatively uniform domed seal around the fiber despite the asymmetry of the open C coil. It took under 10 seconds to heat the part to soldering temperature

Hermetic Sealing a Ferrule & Fiber Optic Cable

To heat a Kovar ferrule and fiber optic cable to 297 °F within 10 seconds for a soldering application, to form a hermetic seal

Hermetically sealing a fiber optic cable in a kovar ferrule

Induction heating provides instant start up time, requiring very little power resources, pin point accuracy, a clean source of heat which is easily integrated into existing automated systems

Soldering a kovar piece with glass to a copper base for a photon light source

Induction heating provides ability to use same equipment for both assembly and repair, hands-free heating that involves no operator skill for manufacturing, and uniform control of heat from part to part
