Abstract:
An edge card for use with an edge card connector, the edge card including a card body with first and second opposing ends interconnected by an insertion edge that extends longitudinally between the first and second ends, comprising:a plurality of conductive contact pads disposed in a row along the insertion edge, the plurality of contact pads including individual signal contact pads and ground contact pads, each of the signal and ground contact pads having a uniform height so as to define a common, upper extent of said plurality of contact pads, said signal and ground contact pads being arranged in a pattern along said insertion edge so that at least one ground contact pad is arranged adjacent to at least one signal contact pad; the signal contact pads being wider in their extent along said insertion edge than said ground contact pads, whereby said signal contact pads have a greater conductive surface area within their common, upper extent than said ground contact pads and whereby capacitance of said signal contact pads is increased between said signal contact pads and said adjacent ground contact pads to thereby reduce impedance of said circuit card contact pads.
