An electronic module includes a circuit board, a first component, and a socket element with a first surface and a second surface opposite the first surface. The first surface lies on a surface of the circuit board and is fixed to the circuit board. A second component is secured to the socket element and is electrically connected to the circuit board via the socket element. A protective compound is arranged on the surface of the circuit board and encapsulates the first component. The socket element is partly embedded into the protective compound such that lateral flanks of the socket element are covered by the protective compound, and the second surface of the socket element protrudes out of the protective compound. Connection elements of the socket element and connections of the second component are connected via a welding connection. Second components are attachable to the circuit board in a reliable manner.
