Abstract: PURPOSE:To prevent exfoliation of a copper plating layer at the time of cutting and thereby to attain high quality by a method wherein a part of the copper plating layer is removed by making a hole around a position deviating from the center of a through hole and then a board is cut along a part wherein no copper plating layer exists. CONSTITUTION:In a board 2 wherein a plurality of through holes 1 are formed, a hole 3 is made around a position deviating from the center of each through hole 1 onto the side to be formed as an end face. By this boring, a copper plating layer 4 on the lower side of a broken line (b) of the the through hole 1 is removed. Next, the board 2 is cut in a part of the through hole 1 wherefrom the copper plating layer 4 is removed, i.e. along the broken line (b), and thereby an end face through-hole printed circuit board is completed. On the occasion, cutting is made along the broken line (b) by holding a part on the upper side of the broken line (b) by cavity side parts 5 and 6 between and by making a force side part 7 rise. Accordingly, the cutting is conducted in the part wherein no copper plating layer 4 exists. Therefore no stress occurs in the copper plating layer 4, and thus no exfoliation of the copper plating layer 4 from the board 2 occurs.

IPC: G11B7/26
Filed: 1986-02-17
Abstract: PURPOSE:To reduce the center shift degree between both optical disk substrates by forming a matching pattern at a part of each disk substrate and detecting the direction and degree of the center shift between both substrates from a moire pattern formed by the matching patterns of both disk substrates when they are set opposite to each other. CONSTITUTION:Two sheets of substrates 11 and 12 are formed with a stamper containing a pattern used as a metallic mold. Thus the center matching patterns P1 and P2 are obtained. A recording layer forming area B1 is not provided on the pattern P1 and another area B2 is spread over the pattern P2. Then a recording layer 14 formed on the pattern P2 functions as a reflecting film and a moire pattern can be seen clearly from an upper side. Then an adhesive 15 is applied between both substrates 11 and 12 and the pressure is applied to the adhesive 15 to spread the adhesive 15. At the same time,both patterns P1 and P2 are put close to each other. A moire pattern is produced on the substrate 11 if some shift is produced between the positions of both patterns P1 and P2. Thus it is possible to know the direction and degree of the center shift between both substrates 11 and 12 from said moire pattern.
