Abstract
An electronic module has a first circuit board element, a second circuit board element, and a spacer. Together, the first circuit board element, the second circuit board element, and the spacer enclose a central cavity, in which components attached to the first circuit board element are accommodated. Respective annular circumferential microstructures are provided on a surface of the first circuit board element directed outward and on a surface of the second circuit board element directed outward, adjacent to an outer periphery of the first circuit board element. In this region, a sealing ring is formed, which has a form-closed connection to both the first and the second circuit board element by means of the microstructures of the first and the second circuit board element. The sealing ring can be made of a resistant plastic, which is molded on by injection molding in the liquid state in the region of the outer periphery of the first circuit board element and flows into recesses of the microstructures and, after the curing, forms the form-closed and sealing connection between the two circuit board elements and the sealing ring thereby formed.
