Title: Manufacture of ceramic circuit board
Inventor: NAKAMURA HISASHI
IPC: H05K1/16
Filed: 1990-06-08
Abstract: PURPOSE:To obtain a thick-film resistor layer by forming a circuit conductor layer by a direct electroless copper plating method after roughening the surface of a ceramic insulating substrate and forming the thick-film resistor layer on the main surface of the insulating substrate and thick-film conductor layers which become external connecting terminals at both end sections of the resistor layer. CONSTITUTION:After through holes 6 are formed at prsescribed locations of a ceramic insulating substrate 5, the substrate 5 is subjected to an etching process in a high- temperature alkaline solution so as to finely roughen the surface of the alumina. Then thick-film conductor layers 8 for external connecting terminals are formed on one main surface of the substrate 5 by applying conductor paste prepared by mixing silver, glass flit, and resin binder together to the surface and calcining the paste in the air. After forming the layer 8, a thick-film resistance layer 7 is formed by applying ruthenium oxide-based glaze paste having a prescribed resistance value to the layer 8 and calcining the paste in the air. After an insulating protective film 9 and activating layer 10 are formed, a circuit conductor layer 12 of metallic copper is formed on the entire surface of the ceramic insulating substrate 5 including the through holes 6 by dipping the substrate in a electroless copper plating liquid.

Abstract: PURPOSE:To reduce the cost of manufacture and to prevent thermal deterioration of a circuit board by applying a solder material on pads of the circuit board and by heating it. CONSTITUTION:A solder deposition composition 4a in the form of paste is applied on a pad 2a on the upper-surface side of a circuit board 1, while a solder deposition composition 4b in the form of paste is applied on the upper side of a heating plate 3 so that it corresponds to a pad 2b on the lower-surface side of the circuit board 1. Next, the heating plate 3 is heated and thereby a solder educing reaction of the solder deposition composition 4b is made to proceed halfway approximately, and then the circuit board 1 is put thereon. In this state, the whole is heated so as to facilitate the solder deposition reaction of the solder deposition compositions 4a and 4b and thereby molten solder is deposited on the surfaces of the pads 2a and 2b. Then, cooling is made until the solder is solidified and the circuit board 1 is detached from the heating plate 3. According to this constitution, solder layers can be formed on the pads 2a and 2b on the opposite sides of the circuit board 1 by heating of one time and the cost of manufacture can be reduced, while thermal deterioration of the circuit board 1 can be prevented.
