The invention relates to a control unit (2) for a motor vehicle. The control unit (2) has an electrical SMD (surface mounted device) component (4) having at least one corresponding connection pin (18, 30) and a circuit board (8). The circuit board (8) has at least one soldering surface (12). The soldering surface (12) is permanently connected to the circuit board (8). The soldering surface (12) and the connection pin (18, 30) are connectable to each other in an electrically conductive and firmly bonded manner by means of a soldering process. According to the invention, a contact hold-down piece (40) is permanently connected to the circuit board (8). The connection pin (18, 30) is positioned in such a manner by the contact hold-down piece (40) that, when the connection pin (18, 30) is connected to the soldering surface (12) in an integrally bonded manner, the connection pin (18, 30) and the circuit board (8) have a predetermined distance (A) from each other.
Abstract:
Methods and apparatuses are disclosed for fabricating a printed circuit board (PCB) having electromagnetic interference (EMI) shielding and also having reduced volume over conventional frame-and-shield approaches. Some embodiments include fabricating the PCB by mounting an integrated circuit to the PCB, outlining an area corresponding to the integrated circuit with a number of grounded vias, selectively applying an insulating layer over the PCB such that at least one of the grounded vias are exposed, and selectively applying a conductive layer over the PCB such that the conductive layer covers at least a portion of the integrated circuit and such that the conductive layer is coupled to the at least one of the grounded vias that are exposed.
Abstract:
A light source structure includes a light-emitting diode (20), an optical component (90), a frame (40) and a mounting substrate (10). The light-emitting diode emits light. The frame has an inside face (45) defining an inside area and outside face (43) with an attachment opening (42) extending between the inside and outside faces. The light-emitting diode (20) is disposed in the attachment opening (42) to emit the light toward the inside area of the frame. The frame (40) houses the optical component (90) in the inside area of the frame. The mounting substrate (10) has a base member (11), a copper layer (12) that is laminated on the base member, and a resist film (13) that is laminated on the copper layer. The resist film has a first aperture with the light-emitting diode extending through the first aperture such that the light-emitting diode is electrically coupled to and mounted on the copper layer. The mounting substrate is disposed on the outside face of the frame.
