Alumina Ceramic Substrate

I need a metallised ceramic substrate for a power or RF module. Who makes it, and who drills the vias?

What it is

Thin flat ceramic carrying metallised conductor patterns for electronic packaging. Chosen for thermal conductivity and thermal expansion match to semiconductors rather than for structural properties.

Typical dimensions
Typically 0.010 to 0.100 inch thick; panel size varies by process.
Also known as
substrate, DBC, AlN substrate, ceramic PCB, electronic ceramic
