About Technical Development

We have provided DCB Substrates for more than 30 years, as one of our major backbone business. Copper plates are directly bonded with ceramic substrate, and has advantages on high dielectric strength and excellent heat dissipation, and NGK-ED has gained high reputation and keep strong relationship with customers. For long market has been rather quiet, but now suddenly spot light posed again, by outcoming new industries of wind-power generator or electric automotives etc.

High Performance supported by Patents

NGK-ED's DCB was developed by our own technology, starting with raw material development to product finishing, to provide highest level of quality requirement. Our patented "ZDA" further enhanced, by conventional alumina plus Zirconium to achieve higher ceramic strength. This enables to make thinner substrate, and reduces thermal resistance, resulting higher heat dissipation efficiency. This know-how further progressed to "New ZDA" (patented) development. It is now loaded on newly developed hybrid car by one of famous European automobile makers, and our reputation is being spread to related industries.
