METAL CLAD LAMINATE PLATE AND PRODUCTION METHOD THEREOF
FIG1 is a schematic view illustrating a continuous hot press apparatus used in the production process of a metal clad laminate according to one embodiment of the present invention  FIG2 is a schematic view illustrating a vapor deposition apparatus used in the production process of a metal clad laminate according to one embodiment of the present invention 
For example, FIG1 shows a continuous hot press apparatus 10 used in the production process of a metal clad laminate according to an embodiment of the present invention. The continuous hot press apparatus 10 has a pair of heating rolls 7 which at least include a metal elastic roll 8. In FIG1, the pair of heating rolls 7 comprises a metal elastic roll 8 and a metal heating roll 9. A thermoplastic liquid crystal polymer film 2 unwound from an unwinding roll 22 and a metal sheet 6 unwound from an unwinding roll 21 are introduced to the pair of heating rolls 7. Preparation of a single-sided metal clad laminate will be explained with referring to FIG1. The thermoplastic liquid crystal polymer film prepared in the previous step (1) and a rolled copper foil (produced by JX Nippon Mining & Metals Corporation under a name of BHYX-HA-V2, Rz: 0.9 µm) with a thickness of 12 µm were prepared as a thermoplastic liquid crystal polymer film 2 and a metal sheet 6, respectively. To a continuous hot roll press apparatus 10 were attached a metal elastic roll 8 and a metal heating roll 9 as a pair of heating rolls 7 for lamination. The thermoplastic liquid crystal polymer film 2 and the metal sheet 6 were introduced in such a way that the thermoplastic liquid crystal polymer film 2 came into contact with the metal elastic roll 8 and the metal sheet 6 came into contact with the metal heating roll 9. The thermoplastic liquid crystal polymer film 2 and the metal sheet 6 were thermocompression-bonded by the pair of heating rolls so as to form a single-sided metal clad laminate 19.  FIG2 shows a vapor deposition apparatus used in the production process of a metal clad laminate according to one embodiment of the present invention. As illustrated in FIG2, the obtained single-sided metal clad laminate 19 is introduced from an unwinding roll 12 using a guide roll 15 such that the surface of the metal sheet 6 in the single-sided metal clad laminate comes into contact with a heating roll 13 used in vapor deposition (hereinafter sometimes refers to as "vapor deposition-applied heating roll"). In other words, the liquid crystal polymer film 2 in the single-sided metal clad laminate does not come into contact with the vapor deposition-applied heating roll 13, but is introduced in such a way that the surface of the liquid crystal polymer film 2 is directed to the opposite side of the vapor deposition-applied heating roll 13. Thereafter, onto the single-sided metal clad laminate 19 introduced to the vapor deposition-applied heating roll 13, a metal vapor deposition layer (a copper vapor deposition layer) is formed on the liquid crystal polymer film 2 that is outward of the vapor deposition-applied heating roll 13. The formation of the metal vapor deposition layer is performed by irradiating an electron beam from an electron gun 18 onto a vapor deposition source-containing crucible 17 that is disposed below the vapor deposition-applied heating roll 13 to heat the vapor deposition source. Then the double-sided metal clad laminate 21 in which the metal vapor deposition layer is formed is guided by a guide roll 16 and is wound by a winding roll 14. The resultant double-sided metal clad laminate has a laminate structure in which the metal sheet layer, the thermoplastic liquid crystal polymer film layer, and the metal vapor deposition layer are laminated in this order. Formation of a copper vapor deposition layer will be explained with referring to FIG2. A roll-to-roll processing using a vacuum vapor deposition apparatus (produced by ROCK GIKEN KOGYO Co., Ltd. under a name of RVC-W-300) was employed to form a copper vapor deposition layer (thickness: 0.3 µm) on the surface of the liquid crystal polymer film 2 of the above single-sided metal clad laminate 19.
