Patent ID: 8226874

Claim:
A process for making a protective assembly for protecting multiple circuits of similar topography, said process comprising: conforming a flexible film of a watertight material to a topography of a first circuit among the multiple circuits of similar topography, wherein the conforming includes urging the flexible film into contact with the first circuit under differential pressure and wherein the flexible film is non-adhesive to the circuit; forming a flexible layer of the protective assembly over the flexible film and the first circuit while urging the flexible film into contact with the circuit, wherein: the forming includes adhering the flexible layer to the flexible film; the flexible layer is conformed to the topography of the circuit; forming a rigid support over the flexible layer, wherein the protective assembly includes the flexible film, the flexible layer and the rigid support; removing the protective assembly intact from contact with the first circuit, wherein the flexible film and flexible layer retain conformance with the topography of the circuit following removal of the protective assembly; thereafter, installing the protective assembly including the flexible film, flexible layer and rigid support over a second circuit among the multiple circuits of similar topography and securing the protective assembly over the second circuit to create a watertight seal of the flexible film about the second circuit; operating the second circuit at an ambient temperature below 0° C. while the watertight seal is maintained; and thereafter, removing the protective assembly intact from the second circuit and repeating the installing, securing and operating steps for a third circuit among the multiple circuits of similar topography.
