Mechanical assembly and electrical interconnection of the functional components of an active implantable medical device

A process for mechanical assembly and electrical interconnection of functional components of an active implantable medical device, wherein the functional components, including at least one electronic circuit module, a power supply battery, and a series of feedthrough terminals able to be linked to a connector head joined to the case, are intended to be integrated in a common case after being interconnected, comprising the steps of:

• preparing a flex circuit that is able to be electrically and mechanically linked to the respective functional components, wherein the functional components are comprised of homologous metallizations, and wherein the flex circuit is comprised of a series of pads for linking to homologous metallizations of the functional components;
• and
• mechanically assembling and electrically linking the pads of the flex circuit to the homologous metallizations of each functional component, wherein the step of mechanically assembling and electrically linking the pads of the flex circuit to homologous metallizations of the functional components further comprises applying an intermediate anisotropic conductive material between the pads and the respective metallizations, and polymerizing the material, under controlled conditions of pressure, temperature and duration.
