Abstract: A system for removing electrical charges from a memory card when the card is electrically coupled to a header connector of an electronic apparatus. The header connector has a plurality of pin terminals mounted therein, including a plurality of pin signal terminals. The memory card includes a circuit substrate, and an elongate receptacle mounted at an edge of the substrate. A plurality of receptacle terminals are mounted within the receptacle, and include receptacle signal terminals which are adapted for electrical connection to corresponding pin signal terminals. A pair of cover plates sandwich the circuit substrate therebetween. At least a portion of one of the cover plates is conductive. The receptacle terminals includes at least one receptacle ground terminal substantially the same length as the other of the receptacle terminals and coupled to the conductive portion of the one cover plate.

Abstract: A permanently solderable palladium-nickel electroplated coating is formed on electrically conductive surfaces. The coating has a first alloy layer of 46 to 82 atomic percent palladium and 18 to 54 atomic percent nickel. This first layer is covered by a continuous second layer of 96 to 100 atomic percent metallic palladium and 0-4 atomic percent nickel. The second layer has a thickness of up to twenty angstroms. The second layer is formed by dipping the first layer in a solution of sulfuric or hydrochloric acid.
