Abstract

An apparatus for manufacturing a printed circuit board that uses conductive bumps to interconnect layers includes: a conveyor unit, which is configured to transport a board that has the conductive bumps formed on one side; an upper roller and a lower roller, which press the board and an insulator together; an elastic coating layer, formed on a surface of the upper roller; and a cleaning device, which removes impurities from a surface of the elastic coating layer. The apparatus does not require a separate device for performing a cushioning function and a detaching function between the bumps and the rollers, and the rollers can be kept clean using a cleaning device.
