CONDUCTIVE PASTE FOR MULTILAYER WIRING BOARD

摘要

PURPOSE: To provide a conductive paste for a via-conductor which can suppress the occurrence of inner pores or cracks while suppressing the resistance value of the via-conductor low. CONSTITUTION: This conductive paste which forms a conductor (via-conductor), being charged in the through hole of a glass ceramic board sintered at a low temperature, contains matter A consisting of metal and matter B consisting of conductive metallic oxides as its main components. It is arranged so that the relation of T1
