Abstract

PROBLEM TO BE SOLVED: To obtain an epoxy based flexible printed wiring board in which resin smear due to heating of drill is suppressed at the time of drilling a through hole, increase of labor is prevented and cost is lowered by facilitating the manufacture, and flexibility is imparted while sustaining the circuit characteristics of glass base epoxy resin board. SOLUTION: Copper patterns 2 are provided on the opposite sides of a glass base epoxy resin 1 and applied, on the outer side face thereof, with a protective layer 3 of epoxy resin thus forming a glass base epoxy resin flexible circuit board 4. Glass base epoxy resin circuit boards 7, each comprising copper foil patterns 6 provided on the opposite sides of a glass base epoxy resin 5, are hot pressed through a glass base epoxy resin prepreg 8, on the opposite sides of glass base epoxy resin flexible circuit board 4 at an appropriate part thereof thus forming a highly rigid part. Consequently, only the part of glass base epoxy resin flexible circuit board 4 is made flexible.

As shown in FIG. 3, the flexible printed wiring board 26, which is the main part, is cut into a predetermined size by partially using an adhesive 27 on both surfaces in appropriate places, and the copper foil 23 is etched to form a circuit pattern. Two or more of the formed flexible base materials 20 are bonded together to form a highly rigid portion (rigid portion), a through hole 28 is bored, and the inner surface thereof is plated. In addition, recently, after the copper foil of the flexible base material is etched, a glass base material epoxy resin substrate or a bake plate is attached by a prepreg or an adhesive. Since it is formed as described above, only the flexible printed wiring board 26 is a flexible portion having flexibility, and the portion where the flexible base material 20 is bonded to the flexible printed wiring board 26 has high rigidity and flexibility. There is no rigid part.

However, in the printed wiring board formed by the above-mentioned conventional method, heat generated by the drill causes
The adhesives 22, 24, 27 may melt and remain as resin smears 29 on the cutting surface of the copper foil 23 in the through holes 28, which may reduce the connection reliability of the plating applied to the inner surfaces of the through holes 28. To overcome this drawback, the through hole 28
Before plating the inner surface, a chemical treatment or a pretreatment such as plasma cleaning is performed to remove the resin smear 29, but there is a problem in that the number of steps is increased and the cost is increased. Alternatively, there is a case where a protective layer made of a polyimide film or a polyester film 25 is provided only on the flexible part in order to use as little adhesive as possible in the part where the through hole 28 is drilled, but it is flexible by avoiding the rigid part. There is a problem that the work of providing the protective layer only on the part is required, which increases the number of steps and increases the cost. In addition, a flexible base material made of a polyimide film or a polyester film, a glass base material epoxy resin substrate or a bake plate bonded with a prepreg or an adhesive is used to obtain circuit characteristics (for example, a glass base material) obtained by a single substrate. There is a problem that the circuit characteristics obtained with the epoxy resin substrate) cannot be adopted as they are, and a complicated simulation of the electrical characteristics generated by using different resin materials is required, and an increase in cost cannot be avoided. .
Further, since the polyimide resin has high hygroscopicity, in a flexible substrate using a polyimide film, if the amount of moisture absorption is large, swelling or peeling of the flexible substrate may occur at high temperature during soldering. There was a problem.
