摘要： A method for manufacturing a prepreg in which a reinforcing substrate is impregnated with a thermosetting matrix resin. In the method, the reinforcing substrate is moved in a traveling direction. The thermosetting matrix resin is supplied to an outer circumferential surface of a transferring roller. The thermosetting matrix resin which substantially contains no solvent and which is in. a molten state is transferred from the outer circumferential surface of the transferring roller to a first surface of a reinforcing substrate while the reinforcing substrate moves. The thermosetting matrix resin which is transferred to the first surface is forced to permeate through the reinforcing substrate by pressing at least one pressing roller on the thermosetting matrix resin transferred to the first surface while the reinforcing substrate moves. The reinforcing substrate impregnated with the thermosetting matrix resin is heated to semi-cure the thermosetting matrix resin.

摘要： The present invention has been aimed to propose a process and a device of fabricating a prepreg for a printed circuit board which are capable of controlling respective thicknesses of resin layers on the opposite surfaces of a resultant prepreg, removing air bubbles from the resultant prepreg, and improving productivity.The present invention is a process of resin-coating the opposite surfaces of an elongated substrate sheet 3. The process includes the steps of: feeding the substrate sheet 3 while tensioning the same in a feeding direction along the length of the substrate sheet 3; coating, by the coating head 2 of the first dispenser 1a, one surface of the substrate sheet 3 with the fluid resin 4 while pressing against the one surface to bend the substrate sheet 3; and subsequently coating, by the coating head 2 of the second dispenser 1b, the other surface of the substrate sheet 3 with the fluid resin 4 while pressing against the other surface to bend the substrate sheet 3. A die coater and a roll coater can be used as the first dispenser 1a and the second dispenser 1b.
