Capacitor manufacturing process

摘要

A method of fabricating an electrical capacitor from a wound laminate of conductive and non-conductive materials comprises the steps of enclosing the wound laminate in a sealed chamber; drawing a vacuum on the chamber to evacuate any voids in the wound laminate, and then filling the chamber with a pressurized impregnating gas to fill the evacuated voids in the wound laminate; heating the laminate to a curing temperature; applying schoopage metal to opposite ends of the cured laminate; attaching a pair of electrical leads to the schoopage metal on opposite ends of the cured laminate, and encapsulating the cured laminate in a molded polymer.
