Abstract:
1. Apparatus for sealing circuit elements of an electrical circuit between a substrate upon which the circuit elements are mounted and a cover layer, at least some of the circuit elements on the substrate being temperature sensitive, said apparatus comprising: a press having a hollow interior adapted to be connected to a source of heated fluid, said press having an exposed surface that is heated by the heated fluid; a support which carries the substrate and the cover sheet, said support including: a controller which is effective to direct cooling fluid into the hollow interior of individual ones of said conduits which are located at one or more discrete areas along said plate underlying the temperature sensitive circuit elements carried on the substrate, said individual ones of said conduits that receive cooling fluid providing localized cooling of said top plate and the temperature sensitive circuit elements at said discrete areas; said press, when at least partially filled with heating fluid, being movable relative to said support so that said exposed surface of said press contacts the cover sheet which overlies the substrate, said exposed surface of said press being effective to exert sufficient heat and pressure to cause the cover sheet and substrate to bond together while the heat sensitive circuit elements overlying said discrete areas of said top plate are cooled by said individual ones of said conduits receiving cooling fluid.
