Direct Bonded Copper Substrates

DBC ceramic substrate, short for Direct Bonded Copper Ceramic Substrate, is an advanced material composed of a ceramic substrate (typically Al2O3 or AlN) and copper, tightly joined together through a hypo-eutectic process. This unique combination of materials results in a substrate with exceptional thermal conductivity, low thermal expansion, high strength, and excellent wettability for soldering applications.
