ABSTRACT:
An article of manufacture and method for assisting the lamination of printed circuits in a flat bed press, in which a stratiform sheet has a thermoplastic layer, a polymeric release layer on one side, a polymeric stabilizing layer having a melting point higher than the laminating temperature peak on the other side, both bonded to the middle thermoplastic layer which has a glass transition point lower than the laminating temperature peak, and a melting point higher than the peak, and the sheet is characterized by substantial freedom from creases, trapped gases, and contaminants between the layers, and the improved method useing the stratiform sheet in a flat bed press operation.
