The apparatus also may include a logic ring that includes a via to a logic circuit of the PCB and a washer including a substantially flat surface including a high yield strength material. The washer may include a through-hole to accommodate the width of the fastener. The washer may additionally include a plurality of contact fingers extending out from the through-hole. The plurality of contact fingers is configured to contact the logic ring. The washer may be made to be in electrical communication with the chassis when compressed in response to a downward force from the fastener.
