Open the CIPO recordAbstract From the Canadian patent
A method for processing a layered structure incorporating alternating plastic film and electrically conductive layers to enhance thermal and capacitive stability of the structure, which plastic film has molecular bonds oriented in a first axis and a second axis the, method comprising the steps of applying compressive force to the structure in a third axis which third, axis is substantially perpendicular to the first and second axes; and raising the structure from an ambient temperature to a processing temperature while maintaining the compressive force on the structure the process-, ing temperature being sufficiently high to randomize the molecular bonds; and maintaining the structure at …
