    摘要: A method of making a plate through hole printed circuit board, comprises the steps of: a) forming conductive circuit elements (10) on two opposed faces of a paper phenolic containing substrate (11); b) coating the substrate and circuit elements with a de-sensitising material (12); c) forming holes (13) through the substrate, each hole passing through a circuit element on each of the opposed faces of the board; d) treating the board to render the substrate exposed in the holes receptive to the action of a metallic plating solution; e) removing the de-sensitising material; f) printing an acid-resist mask (14) on to both faces of the board, the mask leaving exposed only a small area of the board surrounding each hole therethrough; and g) treating the board with an electroless nickel-plating solution to deposit nickel (15) in the holes to the desired thickness to provide an electrical connection through each hole between two opposed conductive circuit elements.

    摘要: A method for the manufacture of printed circuit boards is provided comprising conditioning the board, activating with a catalytic metal, post-activating, stabilizing and etching the copper surfaces before the desired circuit is formed on the board. This process eliminates the need for a flash coating of copper in the through holes before the use of protective coatings such as imaging resists and soldermasks.

    摘要: The specification described a process for making a plating mask 17, for use in printed wiring board fabrication, with greater precision and definition that has previously been possible. An insulative substrate 11 includes on one surface a thin metal film (13). The film is covered with a relatively thick first mask layer (16) which is selectively removed to expose portions of the metal film, which are in turn removed to expose portions of the insulative substrate (11). The exposed portions of the insulative substrate are covered with a relatively thick plating mask layer (17) which abuts against the first mask layer (16). The first mask layer is then removed, leaving the remaining plating mask layer as a patterned plating mask which is then used as a mask for deposited metal (19) which defines a printed circuit.

    摘要: A rigid-type multilayer printed wiring board is produced by bonding a multilayer printed wiring sheet substantially comprising a thin insulating resin layer (1), at least one metal foil printed wiring layer (8, 11) and a plurality of conductive holes (7) formed through the two layers onto a metal board (10) through an insulation laminate (9). In this method, a multilayer printed wiring interlayer sheet consisting of the multilayer printed wiring sheet retaining a printed wiring pattern unprocessed metal foil (2b) on one surface thereof is prepared first. In this case, a given printed wiring has already been processed on the other surface and sometimes in the inner portion of the interlayer sheet. Then, the other surface of the interlayer sheet is bonded to the surface of the metal board through the insulation laminate. Thereafter, a desired printed wiring pattern is formed on the printed wiring pattern unprocessed metal foil (2b) on the one surface of the interlayer sheet.
