  • Method for manufacturing encapsulated semiconductor devices
    Patent number: 6003369
    Abstract: A method for manufacturing encapsulated semiconductor devices, including rotary speed sensing devices, by using a lead frame. Electrical terminals of the semiconductor device are electrically connected to electrical leads from the lead frame. The semiconductor device is encapsulated in a plastic housing which is also connected to positioning posts located on the lead frame. The electrical leads are disconnected from the lead frame, permitting additional processing of the semiconductor device, including testing.

  • Snap-fit integrated wheel speed sensor assembly
    Patent number: 5920193
    Abstract: A snap fit integrated wheel speed sensor assembly consists of a dust cap which is mounted over the end of a vehicle bearing assembly. The dust cap has an integral sensor-receiving cavity. A vehicle wheel speed sensor is positioned inside of the receiving cavity. A snap ring functions as a compression spring to engage the wheel speed sensor and the sensor-receiving cavity so that the sensing assembly remains stationary in the sensor-receiving cavity while permitting quick, easy and efficient installation and removal of the wheel speed sensor.
