Abstract
Abstract An electronic module is provided that includes a housing having electrically conductive top and bottom housing portions in substantial contact with each other and cooperating with each other to define an opening. A printed circuit board is disposed within the housing and includes an edge connector at least partially extending through the opening in the housing. The printed circuit board also defines a non-conductive through opening configured and arranged so that the housing portions contact each other by way of the through opening. In this way, the housing portions cooperate to subdivide the opening defined by the housing into at least two relatively smaller openings that, as a result of their relatively small size, facilitate containment of electromagnetic emissions generated by the electronic module.
