ELECTROSTATIC DISCHARGE PROTECTION FOR A PRINTED CIRCUIT BOARD Abstract of the Disclosure A printed circuit path, which connects to a reference potential point, is provided along a portion, or more, of a printed circuit board (PCB) assembly which requires protection from electrostatic discharge (ESD). This printed circuit board path has a plurality of intentionally pointed protrusion integrally formed along its length and which point preferably toward the direction from which the electrostatic discharge is likely to approach the printed circuit board assembly; ie. through housing mating edges or housing surface openings. The pointed conductor path is locate closer to the ESD regions to concern than other circuit paths or component solder pads. The pointed protrusion preferentially attract electrostatic discharges to itself rather than allow the discharges to strike other paths or components further in on the PCB assembly, thereby avoiding component damage. - i -
