METHOD OF MANUFACTURING FOR POLYAMIDE METALLIC FOIL LAMINATED BOARD

摘要

PROBLEM TO BE SOLVED: To provide a manufacturing method for polyamide metallic foil laminated board in which a coating liquid is uniformly applied without damaging the surface of metallic foil. SOLUTION: In the manufacturing method for polyimide metallic foil laminated board obtained by applying the coating liquid of at least one selected from polyamide acid solution and polyamide solution on the surface of the metallic foil and heating to form a polyimide layer, the metallic foil is supported by 3 rollers of a front guide roll, a coat roll and a rear guide roll, the transferring quantity of the coating liquid to the coat roll is controlled with a metering roll and the coating liquid on the coat roll is transferred on the surface of the metallic foil by controlling the peripheral speed of the metering roll to 40-60% of the peripheral speed of the coat roll.
