Method for manufacturing an electronic component

摘要

A flexible wiring board is constructed by placing, on a surface of a flexible ultraviolet-transmissive base member in the form of a layer, a conductive member in the form of a layer and a covering member in the form of a layer. The conductive member has an exposed leading area not covered with the covering member. A lead is aligned with an electrode and they are connected together with pressure exerted by a pressure applying jig which is ultraviolet-transmissive. A photosetting adhesive resin capable of shrinking in volume is injected between the flexible wiring board and a printed circuit board. The photosetting adhesive resin is irradiated with ultraviolet passing through the pressure applying jig and the base member. When irradiated with the ultraviolet rays, the photosetting adhesive resin hardens. Volume shrinkage force exerted by the photosetting adhesive resin enhances the connection between the lead and the electrode. Such a connecting procedure can be performed at room temperature thereby cutting down the cost of the flexible board and providing a wider range of applications thereof.
