MULTILAYER PRINTED WIRING BOARD AND PROCESS FOR PRODUCING THE SAME |
摘要 |
<p>A plurality of double-sided boards using a film are attached to each other with a paste coupling layer sandwiched therebetween. In the paste coupling layer, a conductive paste is filled into a through hole formed in provisionally hardened resin, which is hardened. At the same time, second wirings are electrically coupled to each other by using the hardened conductive paste filled in the through holes that have been previously formed in the paste coupling layer. Thus, it is possible to provide a thinned multilayer printed wiring board without using an adhesive.</p> |
