Abstract

The invention relates to the technical field of flexible circuit board production, and particularly discloses a manufacturing process of a flexible circuit board. The process comprises the following steps that an adhesive film part is provided; conductive ink and silk-screen printing equipment are provided, wherein the conductive ink is printed on one side of the adhesive film part by using the silk-screen printing equipment to form a conductive circuit; and an injection mold is provided, wherein a plastic part is formed on the adhesive film part in an injection molding mode by using the injection mold, the conductive circuit formed by printing the conductive ink on the adhesive film part is clamped between the adhesive film part and the plastic part, and the adhesive film part, the conductive ink and the plastic part are combined to form the flexible circuit board. Processes of electroless plating copper, etching and the like of a flexible circuit board in the prior art are cancelled,so that a production process flow of the flexible circuit board is greatly simplified, the production of the flexible circuit board is simpler and more controllable, the production efficiency of theflexible circuit board is improved, and the manufacturing cost of the flexible circuit board is reduced.
