Method for manufacturing flexible circuit

Abstract

The invention discloses a method for manufacturing a flexible circuit. The method uses a roll-to-roll techniques and comprises the following steps of: S1, integrating a conductive layer and a first auxiliary substrate layer into one body and then making the same into a coiled material, using one end of the coiled material as an initial feeding unrolling end and unrolling the end to set length; S2, patterning the conductive layer of the coiled material unrolled to the set length to prepare a required circuit structure; S3, using a first elastomer layer provided with the substrate as a feeding end to be transferred to a pair of roller, transfer printing the circuit structure on the surface of the first elastomer layer, and removing the first auxiliary substrate layer; S4 assembling a chip and the circuit structure by using double-roll pressing and bonding difference so as to obtain a flexible circuit layer semi-finished product; and S5 transfer printing a second elastomer to the surface of the flexible circuit layer semi-finished product, wherein the second elastomer layer is used for the packaging layer of the flexible circuit layer semi-finished product. The method greatly improves the production efficiency of the flexible circuit by combining the process of making the flexible circuit with a roll-to-roll motion platform.

Problems solved by technology

[0006] Generally speaking, these methods of making flexible / ductile circuits focus on improving the performance of the circuit. When faced with large-scale production, they all have relatively large defects in processing efficiency, and they do not contribute to the overall performance of making ductile circuits. The processing technology is integrated and integrated, and the efficiency is more limited
