DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing a printed circuit board that does not require plating on the end surface of the substrate, and particularly to a method for manufacturing a printed circuit board with a metal core.

In general, methods for forming printed wiring on a printed circuit board can be roughly divided into two methods: (2) additive method and (2) subtractive method.

Method (1) involves copper plating or copper plating and etching of the required conductor pattern, as in the case of forming a conductor pattern on a normal glass epoxy substrate or a resin-coated substrate with a metal core. This method is a combination of methods, and method (2) uses a copper-clad laminate as a substrate, similar to a multilayer printed board, and forms a pattern by etching to leave the necessary pattern on the copper plate. It's a method.

Among these methods, only the additive method (1), which includes a plating step, poses a problem of plating adhesion on the end surface of the substrate, which is related to the present invention. By the way, this additive method can be further divided into two methods: a full additive method that forms a pattern using only copper plating, and a semi-additive method that uses both copper plating and etching.

Here, we will explain the case of the semi-additive method. The present invention can also be applied to fully additive methods. The semi-additive method is further divided into two types: the pattern plating method, in which thin-on full-surface copper plating is started, followed by further copper plating after pattern development, and the second method, in which full-surface copper plating is performed initially using a moped method, followed by a second plating method. There are two panel plating methods that do not involve plating.

Here, the subject of the present invention will be explained by focusing on these two methods.
By the way, the problem of plating on the edge of a printed circuit board is
In these two methods, this has traditionally been an important manufacturing problem. In particular, printed boards with metal cores, which are often used in telephone exchanges, etc., differ from ordinary printed boards in that they are shaped first and then plated. This problem has traditionally been one of the most vexing. The metal that adheres to the edge of the printed board may peel off when the printed board slides through the grooves of the rack shelf, and even if it does not fall off, the rust generated by moisture may fall off and form on the printed board. This is because it can cause harmful effects when attached to other substances. In order to prevent such problems, when forming copper patterns by plating or vapor deposition, conventionally a plating resist was applied to the end surface with the tip of a brush or a matchstick, and Efforts have been made to eliminate the plating on the end surfaces by scraping off the etching resist on the end surfaces with a knife. However, such conventional work has drawbacks such as requiring great care as it can cause damage if the resist adheres to the pattern, and is extremely time consuming, inefficient and difficult to automate. The present invention aims to eliminate these drawbacks of conventional manufacturing methods. According to the present invention, in the method of manufacturing a printed board, the entire surface including the end face and both surfaces of a contour-processed board is plated with copper, and the copper plating is formed into a desired pattern by etching. A method for manufacturing a printed board is proposed, characterized in that resist adhesion on the substrate surface is selectively performed by masking the end surface portion of the substrate before formation, and the copper-plated end surface portion of the substrate can be removed by etching during the pattern formation. be done. The first and second examples of the embodiments of the present invention are summarized as follows. First example of embodiment: The pretreatment step for selectively plating the copper layer surface of the substrate surface, which is performed after copper plating is applied to the entire surface including both surfaces and end surfaces of the contour-processed substrate, is a plating resist pattern. A method for manufacturing a printed board comprising the steps of: forming a plating resist on the substrate surface and coating the end surface with a plating resist to prevent plating from adhering to the end surface of the substrate, the method comprising: applying a solvent strippable plating resist solution to the end surface of the substrate; After coating the entire surface of the substrate, the periphery of the substrate including the end face of the substrate is masked in a liquid-tight manner, and the applied resist is selectively peeled off using a solvent only from the remaining open substrate surface, thereby selectively coating the substrate. A method for producing a printed board, comprising: leaving a plating resist on the end face, and then forming a plating resist pattern on the surface of the substrate from which the resist has been peeled off.

Second example of embodiment: A pretreatment step for selectively etching the copper layer surface on the substrate surface, which is performed after copper plating is applied to the entire surface including both surfaces and end surfaces of the contour-processed substrate, is performed on the copper layer surface on the end surface of the substrate. In a printed board manufacturing method that includes a step of forming an etching resist pattern on the substrate surface without leaving any etching resist on the substrate, the peripheral edge of the substrate including the edge of the substrate is masked in a liquid-tight manner, and then the remaining open substrate surface is masked. 1. A method for producing a printed circuit board, comprising applying an etching resist solution to selectively form an etching resist layer on a substrate surface excluding an end surface of the substrate.

By the way, as mentioned above, the present invention is mainly applied to two of the semi-additive methods, the pattern plating method and the panel plating method. The only difference is that only the periphery of the substrate, including the end face, is liquid-tightly sealed using a frame-shaped masking jig and a chemical liquid stripping type liquid resist is used, but the purpose of the processing before and after sealing with the masking jig is different. The two methods are completely contradictory; the former involves resist peeling, and the latter involves resist coating. Therefore, the following explanation will also be given separately for the embodiments of the two methods mentioned above. (1) In the case of pattern plating method FIGS. 1A and 1B are manufacturing process diagrams for forming a pattern on a metal-core reprint board by the conventional pattern plating method, and diagrams showing the state of the printed board in each process.
