Product Information

Graphite jigs are used in the production of semiconductor encapsulations by glass-to-metal sealing or brazing connections. The greatest precision is needed in machining these parts. The graphite grades used must exhibit low abrasion, high edge strength and particularly high resistance to oxidation and carbonizing. 
Raw materials of graphite is from toyo tanso and sgl group. More than 15 years of production experience with processing of high precision CNC machine ensure the quality of our products. 
Our Graphite jigs have been used in following area: 
Quartz crystal units, High Efficiency Semiconductor Devices, power transistors, transistor outline package, glass-to-metal (GTM) hermetic seals, connectors, feedthroughs, and related components for air conditioning and refrigeration applications, high-amperage and power-bolt feedthroughs utilize, highly compressed seals for hermetic sight glasses that are used as windows for visual level and flow indicators in high-pressure or vacuum, sensor feedthroughs applications, Pump Feedthroughs, Hybrid Automotive Compressor Feedthroughs, Initiator Components, Lithium Battery Feedthroughs, hermetic packages for high frequency and fiber optic electronics, surface mount connections, RF50 Ohm electrical feedthrus, DC feedthrus, capacitor feedthrus, multi-pin feedthrus
