INTERPOSER FOR ACTIVE IMPLANTABLE MEDICAL DEVICE

Abstract:

A printed circuit assembly (PCA) for coupling to an IMD feedthrough of an implantable medical device includes a PCB portion and an interposer. The IMD feedthrough has a support structure and a plurality of electrical contacts extending through the support structure. The PCB portion is configured to be arranged relative to the support structure of the IMD feedthrough and includes a plurality of electrical contacts. The interposer is secured to the PCB portion and includes a dielectric over-mold structure and a plurality of leads. Each lead is integrated with the dielectric over-mold structure and includes a weld pad and a solder pad. Each solder pads of the interposer is electrically coupled to a corresponding electrical contacts of the PCB portion to provide an alignment between one or more weld pads of the interposer and one or more corresponding electrical contacts of the IMD feedthrough.
