Abstract

PURPOSE:To manufacture a circuit substrate by good productivity and to scarcely allow thermal influence to a circuit pattern, a substrate body and mounting components by protruding integrally with a substrate body a circuit pattern protrusion on one face of the body, forming all the protrusions in the same height, and providing a plating layer on the protrusion. CONSTITUTION:A circuit substrate body 1 is formed of plastic. Circuit pattern protrusions 11-13 are integrally protruded with the body on the upper surface of the body 1. These protrusions are all in the same height. A through hole 13a is opened at the end of the protrusion 13 of the protrusions 11-13. Plating layers 2 are formed on the protrusions 11-13. The protrusion 1a is integrally formed with the lower surface of the body 1 in response to utility. Since the body 1 has the protrusions of the same height, resist forming work can be continuously conducted to simplify the work.

(Prior Art) Generally, the circuit board body is made of an insulating laminate with grooves formed on it, and a predetermined circuit pattern is formed on the surface of this flat laminate. The subtract method involves etching leaving a desired pattern on the stretched laminate, or after applying adhesive to the laminate, parts other than the desired circuit pattern on the surface are protected with a mesh resist layer.
Thereafter, there is an additive method in which a circuit pattern is formed by chemical plating of steel or nickel directly on the portion where the circuit pattern is not protected by the resist layer.

(Problem to be Solved by the Invention) However, in the conventional example, it is necessary to apply a mesh resist to the surface other than the part where the circuit pattern is to be formed using a screen printing method, but this printing is performed every time. There is a problem that productivity is low due to intermittent work and that the resist application process is costly. In addition, since the circuit pattern section is thinly formed on the surface of the circuit board body, it is easily affected by heat from IC chips and capacitors mounted on the board body. Problems that adversely affect mounted components are rare.
