| abstract | PURPOSE: To avoid the abnormal rise of a continuity resistance by a method wherein base is impregnated with epoxy resin and cured and the resin is brought into a C stage to form a board and a through-hole formed in the board is filled with solventless copper powder-resin system paste and its surface parts are coated with epoxy resin system paint. n CONSTITUTION: When a hole 3 drilled in a paper base epoxy resin laminated board 2 whose both surfaces are coated with copper foils 1 is coated or filled with copper powder paint 4 composed of copper powder-epoxy resin of an A stage, stencil printing is applied to one or two surfaces and the copper powder paint is dried in the air to be in a set-to-touch state. At that time, the time, the resin in the copper powder is in a B stage. Then epoxy resin is applied over surface conductors and the copper powder paint application parts of the hole and dried in the air to be in a set-to-touch state to formresin paint layers 5. At that time, the resin paint is in a B stage. Then the epoxy resin paint and the copper powder paint are simultaneously heated to bring them into a C stage. With this constitution, an initial resistance can be stabilized at a low value and the variation of a PCT treatment can be reduced. n COPYRIGHT: (C)1988,JPO&Japio |
