Ceramic multilayer circuit board and a process for manufacturing the same |
摘要 |
A ceramic multilayer circuit board is provided by sintering a multilayer wiring substrate containing alumina as a main component, which was prepared by the green sheet process, nickel plating and gold plating in this order on the superficial wiring conductor layer, printing a thick film conductor paste on the gold plating layer, firing the printed substrate and finally printing a thick film resistor paste on at least part of the thick film conductor layer and firing to form a thick film resistor layer.
