    摘要: A method produces an undercoat-covered smoothed printed wiring board, requiring no step of polishing the surface of the printed wiring board. A method for producing a solder-resist-covered printed wiring board causes no depression in an area between circuit traces. A printed wiring board so produced is also described. The method for producing a printed wiring board includes applying a photo- and heat-curable resin composition onto at least a part of a surface of a printed wiring substrate; placing an optically transparent smoothing member on the resin layer; moving a hard roller on the smoothing member to thin the applied resin layer to a thickness of interest; placing a negative-image mask on the smoothing member; exposing the applied resin layer to light via the negative-image mask; removing the optically transparent smoothing member; removing a light-unexposed portion of the applied resin layer through development; and completely heat-curing the cured light-exposed portion.

    摘要: A photo-setting and thermosetting resin composition comprises (I) a partial adduct of epoxy resin with unsaturated aliphatic acid, (II) (meth)acrylates, (III) a photocrosslinking agent, (IV) liquid epoxy resin, and (V) a latent curing agent. The resin composition can be easily charged and plugged into a through-hole, does not drip down, and can be effectively photo-set and thermoset. A photo-set product prepared of the resin composition can be easily polished. A plugged-through-hole printed wiring (substrate) board prepared of the resin composition does not cause defects such as hollows, cracks, blisters, peelings and so on, is excellent in solder-resistance, does not corrode a metal part, and can produce an appliance of high reliability and long life which does not occur short circuit and poor electrical connection.
