Abstract
A process for manufacturing an EMI filter feedthrough terminal assembly is provided for mating a feedthrough filter capacitor with an hermetic terminal assembly including a ferrule and one or more lead wires which extend through the ferrule in non-conductive relation. The process includes the steps of placing the hermetic terminal assembly, having a capture flange, into a holding fixture, and forming a seat of non-conductive thermal-setting material onto the terminal assembly within the capture flange. A feedthrough filter capacitor is loaded into the capture flange on top of the seat, and then the seat is cured. A conductive thermal-setting material is dispensed between an outer diameter of the feedthrough filter capacitor and the capture flange. The assembly is then centrifuged to pack the conductive thermal-setting material. The conductive thermal-setting material is then cured between the outer diameter of the feedthrough filter capacitor and the capture flange. Preferably, the height of the capture flange is one-quarter to three-quarters of an axial thickness of the capacitor.
