Process for manufacturing emi filters utilizing counter-bored capacitors to facilitate solder re-flow

A process for manufacturing an electromagnetic interference (EMI) filter for use in an active implantable medical device (AIMD), comprising the steps of:

• providing a capacitor comprised of a dielectric material having active and ground electrode plates therein, and at least one through hole;
• forming a well in a surface of the capacitor at one end of the through hole;
• inserting a pin or a lead wire at least partially into the through hole;
• placing an electrically conductive material in the well, wherein the electrically conductive material comprises a liquid or semiliquid material during at least a portion of the manufacturing process;
• and
• utilizing the electrically conductive material to conductively couple the pin or the lead wire to one of the active or ground electrode plates;
• wherein the electrically conductive material conductively couples the pin or the lead wire to one of the active or ground electrode plates directly and without an intervening conductive termination surface for the electrode plates.
