摘要:
A printed circuit board comprising an insulating board deposited with a catalyst having reactivity against electroless plating deposition, a resist for electroless plating provided on the insulating board excepting the part where a circuit is to be formed and a circuit formed by electroless plating, wherein the resist for electroless plating contains a coupling agent having a function of preventing the catalyst from ionizing. A process for producing the printed circuit board in which the insulating board surface excepting the part where a circuit is to be formed is covered with a resist for electroless plating containing a coupling agent having a function of preventing the catalyst from ionizing. Use of said resist for electroless plating can prevent drop of insulation resistance of the insulating board after moisture absorption.

This invention concerns a method for the manufacture of a printed wiring board which particularly proves useful as a printed coil. This method is characterized by the fact that in the work in process which has undergone the step for formation of a conductor circuit and which has not undergone the step for separation of a plating resist, the plating resist and other insulating substratal material are separated for transfer from the surface of the substrate having the conductor circuit formed thereon.Since this method permits formation of an extremely thin insulating layer and a conductor circuit layer thicker than the insulating layer, it enables production of very thin printed wiring board and printed coil having high circuit density in the surfaces of component layers as well as in the direction of superposition of component layers.

Highly precise wiring formed on an insulating substrate can be obtained by electroless deposition without using a printing process. Said process is characterized by forming an adhesive layer containing a photo-setting substance on a substrate, exposing the adhesive layer to actinic light imagewisely so as to irradiate only portions other than those forming wiring, treating the surface of the substrate with a roughening solution so as to roughen the portions not exposed to actinic light, and subjecting to the conventional treatments for electroless deposition so as to form prescribed wiring on the portions not exposed to actinic light.
