Customized sizes and color for You

Blank ceramic substrates are normally white, gray or beige, if you want other colors,we have a variety of  stabilizers and colorants based on your requirements. Different sizes of bare ceramic substrates can be realised by laser scribing and laser cutting on larger substrates, or they can be supplied directly as individual pieces.

Main Properties for blank ceramic subsrates

Bare ceramic substrates are mainly made from alumina,  ZTA,AlN, Si3N4. Different ceramic substrates made of different materials have  different properties.

Mechanical

Strong mechanical stress, stable shape; high strength, high thermal conductivity, high insulation; strong bonding, anti-corrosion.

maching

The same as the PCB board (or IMS substrate) can be etched with a variety of graphic structures; non-polluting, non-polluting

thermal

substrates for heat dissipation/substrates for Better thermal cycling performance, cycle times up to 50,000 times, high reliability

simplifying

Wide operating temperature -55℃～850℃; coefficient of thermal expansion close to that of silicon, simplifying the production process of power modules.
