1. An manufacturing assembly, comprising:
- a plurality of modular sensor assemblies, each of the plurality of modular sensor assemblies comprising;
a circuit board; and
a plurality of electronic components mounted on a top surface of the circuit board, multiple ones of the plurality of electronic components being mounted in a location on the circuit board corresponding to a location for each of the plurality of modular sensor assemblies;
a framework, comprising;
a supporting structure; and
a wall for each of the modular sensor assemblies, the walls being supported by the supporting structure and having an outer surface and an inner surface separated by a top edge and a bottom edge, the bottom edge configured to be positioned against the circuit board;
wherein the wall comprises a first flange extending from the wall proximate the bottom edge; and
a coating applied to the circuit board top surface along the wall for coupling the wall to the circuit board and providing additional isolation against light for the electronic component, the first flange embedded in the coating for retaining the wall bottom edge against the circuit board;
wherein each of the plurality of modular sensor assemblies is isolated from an emission of an electronic component of another one of the plurality of modular sensor assemblies.

Abstract
An implantable medical device is manufactured with a hermetically sealed housing and a modular assembly enclosed within the housing. The modular assembly includes a circuit board, an electronic component mounted on a top surface of the circuit board, and a wall formed having an outer surface and an inner surface separated by a top edge and a bottom edge, the wall bottom edge positioned against the circuit board such that the wall encircles the electronic component coupled to the circuit board. The wall top edge is coupled to the housing a ferrule in one embodiment.

11. A method for manufacturing a plurality of modular sensor assemblies, comprising the steps of:
-
molding a framework comprising a wall for each of the modular sensor assemblies, the walls supported by a supporting structure and having an outer surface and an inner surface separated by a top edge and a bottom edge; mounting a plurality of electronic components on a top surface of a circuit board, multiple ones of the plurality of electronic components being mounted in a location on the circuit board corresponding to a location for each of the plurality of modular sensor assemblies;
thencoupling the framework to the top surface of the circuit board, the bottom edge of the wall being positioned against the circuit board, wherein each wall of each one of the plurality of modular sensor assemblies encircles corresponding multiple ones of the plurality of electronic components of each corresponding one of the plurality of modular sensor assemblies to provide isolation against at least one of light, heat and fluid for electronic components of each modular sensor assembly; and
thenapplying a coating to the circuit board top surface along the wall for coupling the wall to the circuit board and providing additional isolation against light for the electronic component, wherein the wall comprises a first flange extending from the wall proximate the bottom edge, the first flange being embedded in the coating for retaining the wall bottom edge against the circuit board; and
thencutting the plurality of modular sensor assemblies out of the circuit board. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 25, 26)
