Direct Bonding Copper – A Comprehensive Guide

Direct Bonding Copper – A Comprehensive Guide

Direct Bonding Copper (DBC)is a new type of high-performance heat dissipation material. It is a heat dissipation material that organically combines a copper layer with a ceramic substrate. The copper layer can effectively spread and disperse heat, while the ceramic substrate has good insulation performance and high temperature stability. DBC has the characteristics of good thermal conductivity, high mechanical strength, good impact resistance, and high temperature resistance. It is widely used in electronic packaging, LED lighting, automotive electronics and other industries.
