Title: Manufacture of printed wiring board
Inventor: IKEGAYA FUMITOSHI
IPC: H05K3/24
Filed: 1993-05-19
Abstract: PURPOSE:To prevent generation of migration and reduce generation of warp, by polishing only the pad parts needing soldering by using a mask, and performing selective copper plating. CONSTITUTION:A metal mask wherein the parts needing soldering, such as pad parts 2, 3 for mounting electronic parts and outer terminals are opened is arranged so as to coincide with a specified position on the surface of a multilayered printed board 1. A glass beam is sprayed from above the metal mask and the surfaces of the pads 2, 3 are polished. Thereby binder which has been eluted on the surface of conductive paste and a resin coated part from resin base material are eliminated. The mask is removed, and the multilayered printed board 1 is washed, thereby eliminating polishing particles. After catalytic treatment is finished by using Pd or the like, copper plating is performed. Only the parts needing soldering, such as the pad parts 2, 3, are selectively plated with copper in the above manner. Thereby generation of migration can be wholly excluded, and further generation of warp can be reduced.
