  • Method for reducing shorts on a printed circuit board edge connector
    Patent number: 6055725
    Abstract: An edge connector for a circuit board having a top layer and at least one layer underlying the top layer to form a composite structure. The edge connector comprises a first set of metallic tabs formed on the top layer in a row spaced from an edge of the top layer, with each of the first set of metallic tabs having a plating spoke associated therewith formed in the one layer underlying the top layer. A second set of metallic tabs is formed on the top layer in a row adjacent the edge. A metallic tab of the first set is positioned between a pair of metallic tabs in the second set, however, the surface area of the top layer between each pair of metallic tabs in the second set is substantially free of a plating spoke.
