  • Systems and methods for protecting an electrical component from impact or repeated mechanical stress
    Patent number: 7316574
    Abstract: An electrical component is mounted on a carrier printed circuit board. A first header connector connects the carrier printed circuit board to a printed circuit board on one side of the electrical component. A second header connector connects the carrier printed circuit board to the printed circuit board on the opposite side of the electrical component. The carrier printed circuit board and the printed circuit board are connected so that the electrical component is sandwiched between the carrier printed circuit board and the printed circuit board. The carrier printed circuit board, the first header connector, and the second header connector protect the electrical component from impact and mechanical stress. The carrier printed circuit board redistributes the electrical connection of the electrical component.
