Moreover, serve as light source in lighting industry, electrode in glass and tombarthite melting, and welding equipment. Features of tungsten rod bar:  The outstanding feature of tungsten rod is that they can be batch operated. Among the rod-like metal materials, tungsten rod has the highest melting point. In heat, electric conduction and electron emission, it performs very well.

Aluminum Nitride (AIN) materials play a important roles in the semiconductor industry, the similarities between its thermal profile and that of silicon has made an ideal choice for wafer-related semiconductor applications. Innovacera’s Aluminum nitride wafers have high reliability of Si chip and thermal heat cycling. According to direct wafer bonding technology, polished semiconductor wafers can be bonded together without adhesives. Direct wafer bonding requires very flat and high smooth surface (Ra≤0.05um), Innovacera AlN wafers substrate can meet this requirements. Features High melting point High electrical insulation Lowdielectric constant Higher mechanical strength Superior corrosion resistance against molten metal Thermal and chemicalstability High thermal conductivity (170-220w/mk) Similar coefficient of thermal expansion to that of silicon (si)
