  • Patent number: 7369388
    Abstract: An apparatus for providing electrostatic discharge protection includes a first conductive trace and a second conductive trace. The first conductive trace defines a first conductive periphery and is deposited on a first surface. The second conductive trace defines a second conductive periphery and is deposited on a second surface. The second surface is spaced apart from the first surface by a gap distance and in parallel relation so that a spark gap is defined by the gap distance between the first conductive periphery and the second conductive periphery.
