摘要：Process and machine for manufacturing printed circuit boards wherein a presspacket comprised of at least two press plates of metal material between which is

arranged a printed circuit board composition formed by one or more metal sheets, byone or more layers of insulating material impregnated with polymerizable resins and/orby one or more printed circuit boards with an engraved Image of a circuit, are arrangedbetween the press plates of a press and is pressed, subjecting said press packet to theaction of a variable induction magnetic field which generates induced currents in eachmetal plate and sheet of the press packet, causing the heating of said plates and sheets,in turn causing the heating by thermal conduction of the layers of insulating material,melting and liquefying the resins in said layers of insulating material and adhering theinsulating material to the metal sheets, so that, an raising the temperature even more,the polymerizable resins in the layers of insulating material are then polymerized,resulting, after the cooling of the press packet, in one or more rigid boards suitable formaking printed electronic circuits. The machine to carry out the above process comprisesa variable induction magnetic field generating device adapted to generate inducedcurrents in the press packet's metal plates and sheets, causing them to heat, and meansof controlling the Operation of the magnetic field generating device and controlling thetemperature and pressure to which the press packet is subjected.
