Abstract: An electrostatic discharge protection apparatus is described. A multi-hole conductive layer is placed between a multi-hole structure and an electronic element of an electronic device. The multi-hole electric conductive layer contacts a conductive layer on the inside surface of a case of the electronic device. It dissipates the electric charges accumulated on the multi-hole structure because of a lack of the conductive layer, and thus prevents the accumulated electric charges from discharging to damage the electronic element.

Abstract: A card connector for mounting and positioning a card on a circuit board and electrically connecting the card with the circuit board is provided. The card connector comprises a guiding frame, a connector socket, an isolation film and a conductive film. The guiding frame is set over the circuit board for guiding and accommodating a card. The connector socket is set on the circuit board for electrically and structurally connecting with one end of the card. The isolation film is set on the circuit board between the guiding frame and the circuit board. The conductive film is set on the isolation film between the guiding frame and the circuit board and is electrically connected to a grounding washer on the circuit board. Based on the aforementioned card connector, electrostatic charges in the card can be transferred to the grounding circuit of the circuit board via the guiding frame and the conductive film.

Abstract: An electrostatic discharge protection apparatus for a circuit board is described. The electrostatic discharge protection apparatus has a nonconductive layer and a conductive layer. The conductive layer is used to dissipate electric charges accumulated on the pointed ends of the circuit board, and thus improves the electrostatic discharge protection ability of the circuit board.
