A method of fabricating a ductile circuit

Abstract

Provided is a method for manufacturing a ductile circuit. The method uses a "roll-to-roll" type process, and involves: (S1) integrating a conductive layer and a first auxiliary substrate layer into one body and then making same into a coiled material, using one end of the coiled material as an initial feeding unrolling end, and extending same to a set length after unrolling; (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 a first auxiliary substrate as a feeding end, sending same to a pair of rollers, transfer printing the circuit structure to the surface of the first elastomer layer, and then removing the first auxiliary substrate layer; (S4) assembling a chip and the circuit structure together by using double-roll pressing and a bonding difference so as to obtain a ductile circuit layer semi-finished product; and (S5) transfer printing a second elastomer layer to the surface of the ductile circuit layer semi-finished product, wherein the second elastomer layer is used for a packaging layer of the ductile circuit layer semi-finished product. The method improves the production efficiency of the ductile circuit by combining the process of making the ductile 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
