摘要：
A method for manufacturing a singulated feedthrough insulator for a hermetic seal of an active implantable medical device (AIMD) is described. The method begins with forming a green-state ceramic bar with a via hole filled with a conductive paste. The green-state ceramic bar is dried to convert the paste to an electrically conductive material filling via hole and then subjected to a pressing step. Following pressing, a green-state insulator is singulated from the green-state ceramic bar. The singulated green-state insulator in next sintered to form an insulator that is sized and shaped for hermetically sealing to close a ferrule opening. The thusly produced feedthrough is suitable installation in an opening in the housing of an active implantable medical device.
