1. A process for manufacturing a feedthrough terminal assembly for an active implantable medical device, comprising the steps of:

  • associating a feedthrough capacitor with a conductive ferrule, the feedthrough capacitor having first and second sets of electrode plates, wherein the second set of electrode plates is conductively coupled to the ferrule;

    passing a terminal pin or leadwire through the ferrule in non-conductive relation and through the feedthrough capacitor in conductive relation with the first set of electrode plates;

    placing an insulative shield over a surface of the feedthrough capacitor; and

    conductively coupling electronic circuitry for the active implantable medical device to the terminal pin or leadwire, wherein the insulative shield protects the surface of the feedthrough capacitor from heat, splatter or debris occasioned by said coupling of the electronic circuitry to the terminal pin or leadwire.
