Process for manufacturing a multilayer circuit board |
摘要 |
The multilayer circuit board is constituted of an inorganic insulating material such as a crystallizable glass, crystalline oxide or noncrystallized glass; a conductive material such as a metal or a mixture of a metal with noncrystallized glass; a resistor material consisting of a mixture of a conductive material with the crystallizable glass or noncrystallized glass; and a dielectric material consisting of a mixture of a barium titanate-other oxide mixture with the noncrystallized glass or crystallizable glass, of a lead-containing perovskite type oxide or of a lead-containing laminar bismuth oxide, said board has a multilayer structure wherein a first insulating layer; a first resistor circuit or alternatively first capacitor circuit or alternatively first resistor-capacitor circuit; a second insulating layer; a second resistor circuit or alternatively second capacitor circuit or alternatively second resistor-capacitor circuit are superposed in this order, provided that the second insulating layer has a through-hole(s) filled with the conductive material, and a process for producing the same.
