Conveying and cooling apparatus for a resin composition and conveying and cooling method for a resin composition

A cooling apparatus includes a conveying means which conveys a resin composition formed into a sheet shape along a direction parallel to a surface of the sheet-shaped resin composition and a cooling means which cools the resin composition being conveyed by the conveying means. A temperature of the resin composition just before being cooled by the cooling means is in the range of 40 to 60° C. and the cooling means has a cooling ability to cool the resin composition such that a cooling rate of the resin composition is in the range of 0.2 to 5° C./min. Further, the cooling means includes a fan section having at least one outlet port which discharges cooling air of which temperature is in the range of −40 to 0° C. to the resin composition.

FLEXIBLE LAMINATED BOARD AND MULTILAYER CIRCUIT BOARD

A flexible laminated sheet manufacturing method includes thermocompression-bonding an insulation film formed of a liquid crystal polymer onto a metal foil between endless belts to form a flexible laminated sheet. The thermocompression bonding includes heating the flexible laminated sheet so that the maximum temperature of the sheet is in the range from a temperature that is 45° C. lower than the melting point of the liquid crystal polymer to a temperature that is 5° C. lower than the melting point. The thermocompression bonding also includes slowly cooling the flexible laminated sheet so that an exit temperature, which is a temperature of the sheet when transferred out of the endless belts, is in the range from a temperature that is 235° C. lower than the melting point of the liquid crystal polymer to a temperature that is 100° C. lower than the melting point.
