Title:
METHODS FOR MANUFACTURING SINGLE-SIDED FCCL AND DOUBLE-SIDED FCCL
Document Type and Number:
WIPO Patent Application WO/2023/058855
Kind Code:
A1
Abstract:
The present invention relates to methods for manufacturing a single-sided FCCL and a double-sided FCCL and, more specifically, a method for manufacturing a single-sided FCCL allows a three-layer single-sided FCCL to be formed of a copper layer, an LCP film layer and a PI film layer, so that anisotropy is minimized to be less than that of a conventional two-layer single-sided FCCL formed of only a copper layer and an LCP film layer, and thus tensile strength is improved. Additionally, unlike a conventional method in which an LCP film layer is melted at a high temperature and bonded, in the method for manufacturing a double-sided FCCL, a double-sided FCCL is manufactured by applying an adhesive between a pair of laminates composed of a copper layer and an LCP film layer and binding same. Therefore, constructing equipment for high-temperature lamination is unnecessary, and thus productivity is improved.
