porcelain/ceramic substrate:

curamik® high temperature/ high voltage substrates consist of pure copper bonded to a ceramic substrate such as Al2O3 (Alumina), AlN (Aluminum Nitride), HPS (ZrO2 doped) or silicon based Si3N4 (Silicon Nitride). curamik provides two technologies to attach the substrate with the copper.
