欠点かあった。However, when creating a non-zt through hole by drilling,
Naturally, it is necessary to control the depth of the drill in the thickness direction of the multilayer board, but variations in the thickness of the multilayer board itself are unavoidable in the process of laminating the board, and Okawa's method of work is also In some cases, the distance (h) between the bottom of the blind hole and the conductor in the next layer as shown in Figure 5 varies, resulting in a large change in the electrical characteristics of the conductor, and the residence time of the drill in the blind hole. There was a drawback that smear occurred more frequently at the bottom because it was longer.

うしても除去しなければならなかった。As a method to eliminate these drawbacks, as shown in Japanese Patent Publication No. 59-175796, ``Two insulating plates having through holes in the insulating plates and a conductive circuit pattern formed on only one surface in advance. are placed on the outermost layer with conductor circuit patterns facing each other, and then combined via prepreg, heated and pressurized to form a multilayer board, provided with through holes, and plated with copper on the entire surface. The method of ``forming a conductor circuit pattern'' was considered. However, the density of the resin surface and steel plating filled in the non-through hole is poor, and if left as is, the copper plating and resin would peel off and swell during component mounting, so the through hole was filled by etching. The copper plating on the resin surface had to be removed.

頼性が低下するという問題点があった。(Bulky problem to be solved by the invention) Moreover, in the above-mentioned method, a conductor layer is not formed on the resin surface filled in the non-through hole, so it is not possible to form a conductor layer on the surface of the resin filled in the non-through hole. When soldering leads, if the non-through hole is provided in the electrode portion, it is difficult to solder uniformly over the entire surface of the electrode portion, resulting in a problem that the reliability of component mounting is reduced.
