GLASS CERAMIC SUBSTRATE

摘要

PROBLEM TO BE SOLVED: To suppress the oxidation and diffusion of Ag in a glass ceramic multilayer printed circuit board produced by using Ag as a conductor material. SOLUTION: Glass ceramic layers 2a-2g and Ag conductor layers 3a-3f and 4 are laminated and simultaneously baked to obtain a glass ceramic multilayer printed circuit board 1. The glass ceramic layers 2a-2g are made of an insulation material produced by adding a powdery metal such as Cu or Ni to a glass ceramic insulation material composed of a glass component and a ceramic component.
