摘要:
A case-grounded flash-memory drive has a printed-circuit board assembly (PCBA) with flash-memory chips and a controller chip. The PCBA is encased inside an upper case and a lower case, with a Serial AT-Attachment (SATA) connector that fits through and opening between the cases. The cases can be assembled with the PCBA by a snap-together, ultrasonic-press, screw-fastener, or thermal-bond adhesive method. Dual-axis case-grounding pins draw any electro-static-discharges (ESD) current off the upper case along a primary axis and onto a PCBA ground through a secondary axis washer that is screwed into the PCBA. The primary axis body of the dual-axis case-grounding pins fits around a PCBA notch while the secondary axis passes through a metalized alignment hole for grounding. When the SATA connector is inserted into a host, the host ground sinks ESD currents collected by the dual-axis case-grounding pins.
