IPC: H05K3/42
Filed: 1987-06-03
Abstract: PURPOSE:To prevent the improper precipitation of a copper plating from occurring due to the deterioration of a catalyst between the steps of applying the catalyst and electroless copper plating by forming a film stable for the catalyst solution on a circuit substrate in which a circuit pattern is already formed, forming through holes and then applying the catalyst. CONSTITUTION:Circuit patterns P are formed on both-side copper laminated boards 1, 2, films 4 stable for catalyst solution are formed on the surfaces of the boards on which the patterns P are already formed, and through holes 3 are then formed. Then, catalyst 6 is applied to the inner walls of the holes 3 and the films 4 stables for the catalyst solution, the films 4 are then exfoliated, and electroless plating copper films 7 are then formed on the inner walls of the holes 3 and the necessary parts. For example, the films 4 are formed by dipping them in solvent soluble or alkali soluble resist solution. Or after the patterns P are formed, or the films 4 are exfoliated, electroless plating resistant liquid resist may be formed on unnecessary parts for the electroless plating.
