Product Overview
DBC ceramic copper clad master substrates (mother boards) are the base materials used in the production of DBC circuit substrates. These boards consist of a ceramic core (such as alumina, aluminum nitride, or silicon nitride) with copper layers directly bonded on one or both sides.
As upstream materials, DBC mother boards provide a high-quality foundation for subsequent processes such as circuit etching, patterning, and module assembly. Their uniformity, bonding strength, and thermal performance directly impact the quality and reliability of final electronic products.
