Embodiment 1~3
[0056] Electrolytic copper foil 1 with a thickness of 12 μm was laminated on both sides of a liquid crystal polymer film (manufactured by Japan Goatex Co., Ltd., trade name BIAC, heat distortion temperature: 300° C.) with a thickness of 50 μm and a film thickness tolerance of 5.0%. The metal-clad laminates according to Example 1 were produced by continuous thermocompression bonding between the clad metal pressure rolls. Also, using electrolytic copper foils 2 and 3 with a thickness of 12 μm, both surfaces of the liquid crystal polymer film were continuously thermocompression-bonded in the same manner as above to manufacture metal-clad laminates according to Examples 2 and 3.
[0057] Specifically, both the above-mentioned liquid crystal polymer film and the above-mentioned electrolytic copper foil were made of elongated roll materials, and were placed in a thermostatic chamber during lamination, and the surface temperature was set to 240°C (the temperature difference in the wid...
