Title: Printed wiring board and base material used therefor
Inventor: SOTANI TOSHIYUKI
IPC: H05K1/02
Filed: 1992-02-17
Abstract: PURPOSE:To facilitate the separation of a printed wiring board from a base material used as a substrate during mounting operations by drilling a circular hole or a rhomboid hole at each corner of a check pattern defined on the base material. CONSTITUTION:A printed wiring board can be produced by the use of a base material used as a board 2 in which a circular hole 3 or a rhomboid hole 4 is drilled at each corner of a check pattern defined on the base material. In the base material 2 with such an arrangement, the printed wiring board 1 can be manufactured while the depth of a V-shaped groove used for defining the check pattern and formed on both surfaces of the base material 2 is maintained to such an extent that warpage will not arise due to thermal stress occurring when a wiring pattern is printed by locally reducing the strength of the area where the circular hole 3 or the rhomboid hole 4 is drilled. Hence, a finished printed wiring board can be easily separated from the base material 2. The printed wiring board 1 is rectangular in shape, and each corner thereof is depressed into the shape of an arc. In addition, each corner is chamfered to a predetermined length.
