CONDUCTIVE PASTE AND MULTILAYER PRINTED WIRING BOARD USING SAME |
摘要 |
The present invention provides a conductive paste comprising flake conductive fillers having a 99% cumulative particle size of 25 µm or less and a binder resin as essential components. The flake conductive fillers are metal particles having a silver-copper alloy surface layer. The conductive paste according to the present invention is fused with a part of a copper foil circuit to which the conductive paste is to be connected during connection by heating and pressurization, and has high electrical conductivity and high fill ration in a via hole. Thus, the conductive paste according to the present invention provides a multilayer printed wiring board that has high reliability of connection and excellent interlayer connection. |
