Title: Manufacture of multi-layer printed-circuit board
Inventor: ITO TATSUYA
IPC: H05K1/02
Filed: 1997-06-17
Abstract: PROBLEM TO BE SOLVED: To reduce the continuity defects of a via while keeping adhesion of a wiring pattern in a multi-layer printed-circuit board which is provided with a plurality of layers of wiring patterns, via respective resin insulating layers and with respective vias which set the wiring patterns into continuity. SOLUTION: First, the surface of a resin-insulating layer 6 which is formed in the upper part of a lower-layer wiring pattern 4 formed on a core substrate 1 and in which a via hole 7 is formed on the surface of the lower-layer wiring pattern 4 is roughened by an etchant. Then, the roughened surface 6a of the resin-insulating layer 6 is polished. After that, surfaces 6b, 7a, including the via holes 7 of the polished resin insulating layer 6, are roughened in the same manner. Thereby, a resin residue and a shape defect are hardly generated in the bottom part of a via which is formed later inside the via hole 7, and the close contact strength of an upper-layer wiring pattern which is formed later on the surface of the resin insulating layer 6 is maintained to be strong.

Title: Method for forming split slit and press die therefor
Inventor: FUJIMAKI SHIGETO
IPC: B21D28/00
Filed: 1999-06-07
Abstract: PROBLEM TO BE SOLVED: To prevent occurrence of a metal film's burr at the end-surface through hole of a printed wiring board by inserting a presser member, whose cross-section shape corresponds to the through hole, into the through hole before punching out a split slit so that the outside part of the through hole is removed. SOLUTION: A punch is provided with an insert pin 70 which is engaged with each of engagement channels of a punch main body 25 of the same diameter as the engagement channel while a little smaller in diameter than a through hole 5. When an upper die 19 is lowered with a printed wiring board 1 placed in a lower mold, a protruding part 29 of the insert pin 27 engages with the through hole 5 until protruding somewhat beyond the lower end before the printed wiring board 1 is applied with a shearing force by the punch main body 25. So, a peeling takes place at a cutting tip part of a metal film 9 inside half of the through hole 5, and the insert pin 27 prevents bending inside. Thus, an end-surface through hole 33 with no burr is formed at punching out of a split slit 31.

IPC: G02B5/09
Filed: 1987-06-26
Abstract: PURPOSE:To obtain a rotating polygon mirror made of synthetic resin which has highly durable surface accuracy by varying the thickness of a plate-like part, which connects a boss part forming a hole in the center of the rotating polygon mirror to faces of the polyhedron, in the center and edge part of the surface. CONSTITUTION:The plate-like part 14 tangent to the mirror face part 11 is provided with a curved slope 30A, so that the molding pressure of resin can be uniformly applied to the center (a), an intermediate part (b) and an erect face part (c). Namely, as cross sections I-I-III-III show the center (a), the intermediate part (b) and the edge (c), respectively, slope lengths lambdaa, lambdab and lambdac are set so as to become gradually lower, although the thickness (t) of the bottom of the slope 30A is the same. The titled mirror is constituted so that the molding pressure of resin injected to each face of the mirror face part 11 can be kept uniform. Thus such troubles as the warp and deformation of the mirror face part, which have been difficult to circumvent at the time of molding resin, can be eliminated. Besides, weight of said mirror can be lightened to mass- produce the mirrors without imposing a burden on a drive system and a control system.
