摘要： PROBLEM TO BE SOLVED: To provide a manufacturing method of a prepreg for a copper-clad laminate of high production efficiency and a vertical drying furnace used in the manufacturing by reducing the attachment of tar and poor appearance during drying in the drying method of the prepreg for the copper-clad laminate. SOLUTION: In this manufacturing method of the prepreg for the copper-clad laminate for drying resin varnish impregnated in a fibrous base material by using the vertical drying furnace having up-and-down drying chambers, suction openings are formed on an upper end and a lower end of the up drying chamber, and an exhaust port is formed at its central portion to perform drying. Furthermore, the up drying chamber is provided with upper and lower two drying zones, and temperatures of one or both of hot air and a hot plate supplied to the lower drying zone are lower than a temperature of hot air or the hot plate supplied to the upper drying zone by 5-80°C.

摘要： PROBLEM TO BE SOLVED: To provide a method for manufacturing a prepreg which controls the adhesion amount of resin varnish with a high precision and forms no voids in a base material, and an apparatus therefor.
SOLUTION: The base material 1 is subjected to pressure reducing treatment or evacuation treatment by a pressure reducing means, for example, a suction type backup roll 11 to be stabilized and subsequently coated with the resin varnish 2 by dies 12 and 13. The coated resin varnish is sucked by the suction type backup roll 11 to accelerate the impregnation with the resin varnish and the coated base material is further coated with an insufficient amount of the resin varnish by an other die B13 to manufacture the prepreg. The prepreg manufacturing apparatus is also disclosed.
