Inventor: KOJIMA TOSHIFUMI
IPC: H05K3/28
Filed: 2001-02-05
Abstract: PROBLEM TO BE SOLVED: To provide a printed wiring board which prevents paste from running owing to a decrease in its viscosity caused when hole filling paste charged in a through hole is heated and the surface of the through hole from becoming uneven owing to the paste run and forms no unevenness on a subsequently formed buildup layer, and to provide a multilayered printed wiring board which uses the method. SOLUTION: A hole filling mask having a through hole formed opposite a through hole is arranged over a substrate, and the hole filling paste is pressed in the former through hole through the latter through hole from on the hole filling mask by using a roller type squeeze. After the resin half-sets through a heat treatment, projection parts are polished away to flatten the surface. Then thermal setting is carried out through a heat treatment and the hole filling is completed. On the obtained core substrate, a resin insulating layer and a wiring layer are laminated (built up) alternately by using a known method to obtain a multilayered printed wiring board.
