Patent number: 9064640Abstract: An EMI filtered terminal assembly including at least one conductive terminal pin, a feedthrough capacitor, and a counter-bore associated with a passageway through the capacitor is described. Preferably, the feedthrough capacitor having counter-drilled or counter-bored holes on its top side is first bonded to a hermetic insulator. The counter-drilled or counter-bore holes in the capacitor provide greater volume for the electro-mechanical attachment between the capacitor and the terminal pin or lead wire, permitting robotic dispensing of, for example, thermal-setting conductive adhesive.Type: GrantFiled: June 25, 2013Date of Patent: June 23, 2015Assignee: Greatbatch Ltd.Inventors: Richard L. Brendel, Jason Woods, Jose Luis Lorente-Adame, Robert A. Stevenson, John E. Roberts, Buehl E. Truex
