Abstract: A technique for mounting an electrical component to a circuit board includes deforming each of a number of electrical terminals extending from the electrical component to form a mounting portion and a tip portion extending away from the mounting portion. The circuit board defines a number of bores extending therein from a first surface to a second opposite surface, and the electrical component is mounted to the circuit board with the mounting portion of each of the number of electrical terminals supporting the component against the first surface of the circuit board with each of the tip portions extending into separate ones of the number of bores. The mounting portion of each of the electrical terminals is mechanically and electrically affixed to corresponding electrically conductive pads to thereby surface mount the electrical component to the circuit board. The disclosed technique is particularly advantageous for surface mounting display units.

Abstract: A contact assembly for a circuit board includes a first side with a conductive pad disposed thereon and a second side also having a conductive pad disposed thereon. The contact assembly further includes a conductive contact member. The conductive contact member has an arm with a central portion and an end portion adjacent to the central portion. The contact member also has a second arm which has a central portion and an end adjacent to that central portion. The conductive contact member also includes a junction at the connection between the two arms. The conductive contact member is designed to contact the circuit board. When implemented, it electrically connect the two conductive pads of the circuit board. This attachment creates a complete circuit between the two sides of the circuit board. Additionally, a holder member is coupled to the conductive contact member substantially near the junction and substantially opposite the circuit board.

Abstract: An input circuit for an automotive gauge driver receives a pulse width modulated or pulse frequency signal having a duty cycle representing a parameter to be displayed. A switching transistor controls an RC filter to develop an analog voltage proportional to the parameter. The input circuit biases the transistor to correctly respond to the input signal over a large range of supply voltage and where the ground potential differs from that of the source of the input signal. An output transistor means (or two) in series with a gauge coil (or two) is controlled by the analog voltage to provide coil current to effect linear gauge operation. Diodes in the input circuit limit the analog voltage range to end values which match the turn-on characteristics of the transistor means.
