ABSTRACT:
A vacuum laminating fixture includes a pair of opposed plates having opposed plane faces with a peripheral groove formed in each plate surrounding the face with the grooves matched for receiving a unitary band seal extending between the grooves for sealing the space between the faces of the plates, a vacuum port is formed in the lower plate communicating with the area of the face inside the peripheral groove. The method includes setting up a laminate of plural flexible sheets of circuit, placing the laminate within and between the faces of the plates, drawing a vacuum of 28 inches of mercury for a period of two minutes to completely evacuate the space between the laminate sheets, and thereafter applying a predetermined curing pressure and temperature to the plates within a press.
