Abstract

A method for manufacturing a metal-clad laminate sheet containing (i) a thermoplastic liquid crystal polymer film comprising a thermoplastic polymer, and (ii) a metal foil bonded to at least one surface of the thermoplastic liquid crystal polymer film, the thermoplastic polymer being capable of forming an optically anisotropic molten phase, and the method containing: forming a laminate sheet having the thermoplastic liquid crystal polymer film and the metal foil bonded together; and heat treating the laminate sheet, wherein the heat treatment satisfies conditions (1) and (2): (1) wheat treatment temperature ranges between 1° C. inclusive and 50° C. exclusive higher than a melting point of the thermoplastic liquid crystal polymer film, and (2) a time for the heat treatment ranges from one second to 10 minutes.

Claims

exact text as granted — not AI-modified
1 . A method for manufacturing a metal-clad laminate sheet comprising (i) thermoplastic liquid crystal polymer film comprising a thermoplastic polymer, and (ii) a metal foil bonded to at least one surface of the thermoplastic liquid crystal polymer film, the thermoplastic polymer being capable of forming an optically anisotropic molten phase, and the method comprising:
 forming a laminate sheet having the, thermoplastic liquid crystal polymer film and the metal foil bonded together; and heat treating the laminate sheet, wherein the heat treatment satisfies conditions ( 1 ) and ( 2 ):   ( 1 ) a heat treatment temperature ranges between  1 ° C. inclusive and  50 ° C. exclusive higher than a melting point of the thermoplastic liquid crystal polymer film,   ( 2 ) a time for the heat treatment ranges from one second to  10  minutes.   
     
     
         2 . The method of  claim 1 , wherein the metal foil has a low roughness. 
     
     
         3 - 9 . (canceled)
