Abstract

The invention discloses a process for manufacturing a conductive circuit. The process comprises the following steps: S1, combining a base material layer material and a protective layer material which are prepared in advance through a compounding process; s2, performing die cutting on the substrate layer by using a die cutting process to form a parting line of a circuit area and a non-circuit area; s3, performing vacuum plating of a metal layer on the whole base material layer by using a vacuum plating process; s4, removing the unwanted metal layer in the base material layer, and reserving the required metal layer; and S5, covering the base material layer attached with the metal layer with another protective layer. The technical problems that in the prior art, a silk-screen circuit is high in use cost, insufficient in bonding strength and single in selected material are solved.

Description

technical field [0001] The invention relates to the technical field of silk-screen flexible circuits, in particular to a process for manufacturing conductive circuits. Background technique [0002] Flexible circuit boards are often used as basic accessories for various electronic devices. The manufacturing method of the flexible circuit board in the prior art is complicated, which requires many processes such as copper sinking and etching. As a result, the existing flexible circuit board has the defect of low production efficiency. In addition, the existing process also has technical problems such as the high manufacturing cost of the flexible circuit board and the difficulty in controlling the manufacturing process of the flexible circuit board. Based on this, Chinese patent CN111867265A discloses a manufacturing method of a flexible circuit board, which includes the following steps: providing a flexible substrate, flexible silver paste and a screen printing device, and u...
