Embodiment Construction

[0073] The method for producing a metal-clad laminate of the present invention can continuously produce a plurality of metal-clad laminates in which a metal foil is laminated on at least one surface of a thermoplastic liquid crystal polymer film.

[0074] (thermoplastic liquid crystal polymer film)

[0075] The thermoplastic liquid crystal polymer film used in the production method of the present invention is formed of a melt-formable liquid crystal polymer. The thermoplastic liquid crystal polymer is a polymer capable of forming an optically anisotropic melt phase, and its chemical constitution is not particularly limited as long as it is a liquid crystal polymer that can be melt-molded. Thermoplastic liquid crystal polyester amides with amide bonds, etc.

[0076] In addition, the thermoplastic liquid crystal polymer can be formed by further introducing imide bonds, carbonate bonds, carbodiimide bonds, isocyanurate bonds, and other bonds derived from isocyanates into aromati...

Abstract

The present invention provides a method for efficiently producing a metal-clad laminate. In the above manufacturing method, prepare a pair of pressure rollers (r 1 , r 2 ), a pair of release material unwinding rollers (16, 16), two or more unwinding rollers that release the constituent materials of the metal-clad laminate, so that the above constituent materials at least form a state where the metal foils are adjacent to each other (M) / (M ), and a pair of release materials (C 1 , C 2 ) each of the unwinding rollers is arranged so as to sandwich the entirety of the above-mentioned constituent materials. A pair of release materials (C 1 , C 2 ) clamp the above-mentioned constituent materials after heating in advance, and use the above-mentioned pair of pressure rollers (r 1 , r 2 ) to perform thermocompression bonding on the whole, and then pass through a peeling process to manufacture two or more clad metal laminates.

Description

[0001] Associate application [0002] This application claims priority based on Japanese Patent Application No. 2018-178691 filed in Japan on September 25, 2018, the entirety of which is incorporated by reference as a part of this application. technical field [0003] The present invention relates to a method for producing a metal-clad laminate comprising a film (hereinafter sometimes referred to as thermoplastic liquid crystal polymer) capable of forming an optically anisotropic molten phase (hereinafter sometimes referred to as a thermoplastic liquid crystal polymer). This is referred to as a metal-clad laminate in which a metal foil is laminated on at least one surface of a thermoplastic liquid crystal polymer film (or a metal-clad laminate in which a metal layer is provided on at least one surface of a thermoplastic liquid crystal polymer film). Background technique [0004] Thermoplastic liquid crystal polymer films are known to be excellent materials such as high heat ...
