Title:
LIQUID CRYSTAL POLYMER FILM FOR FLEXIBLE PRINTED CIRCUIT BOARD
Document Type and Number:
WIPO Patent Application WO/2021/227505
Kind Code:
A1
Abstract:
The present application provides a liquid crystal polymer film for a flexible printed circuit board. The material of the liquid crystal polymer film comprises a poly-p-phenylene dimethylformamide resin and a polyphenylene sulfide resin, the longitudinal tensile strength of the liquid crystal polymer film is less than the transverse tensile strength thereof, and the longitudinal elongation at break of the liquid crystal polymer film is greater than the transverse elongation at break thereof.
