IPC: H05K3/46
Filed: 1992-06-15
Abstract: PURPOSE:To reduce the number of holes by realizing conduction between upper and lower surfaces by shaping a hole in a multilayer printed wiring board and then cutting off the conduction. CONSTITUTION:A hole 3 of a small diameter is made to pass through a multilayer printed wiring board 1 and a hole 4 whose diameter is larger than that of the hole 3 is shaped up to a specified depth of the wiring board 1 in the same position. Then, after upper and lower surfaces of the wiring board 1 are made conductive by a method such as plating, a bottom of the hole of the large diameter is cut with a drill whose diameter is larger than the small diameter of the hole 4 and smaller than the large diameter thereof; thereby, conduction between up and down of the wiring board is cut off. Since two or more conductions are thereby possible by one through-hole 6, the number of holes 3, 4 of the printed wiring board 1 can be reduced and troubles such as adhesion defective of plating metal can be prevented.
