Apparatus for laminating multilayered printed circuit boards |
摘要 |
An apparatus for laminating multilayered printed circuit boards while radically reducing the volume of inert gas that must otherwise be used to effect the lamination process. The invention employs a novel ring assembly, each such assembly disposed on a moveable, horizontally disposed shelf. Each such ring assembly comprises a hollow circular cylinder, the interior of which is adapted to radially enclose a multiple layer circuit module mounted on a heating platen. The axial surfaces of the cylinder are capped by a pair of seal plates and O-rings to form a gas-tight laminating chamber. Each shelf is adapted to travel vertically along a pair of support tubes whereby the entire array of shelves may be compressed relative to the respective shelves by a hydraulic or pneumatic cylinder the rod of which is affixed to the bottom surface of the lowermost shelf.
