Patent ID: 6994563

Claim:
A daughter card comprising: an edge portion insertable into a connector on a motherboard; a first row of contact pads extending along a first side of the edge portion; at least one device including device terminals through which electrical signals are driven; a plurality of first circuit traces, wherein each of the first circuit traces extends from an electrical connection at one of the contact pads in the first row to an electrical connection at one of the device terminals, wherein each of the first circuit traces includes a first enlarged section disposed at a location spaced apart along the first circuit trace from the contact pad from which the first circuit trace extends and from the device terminal to which the first circuit trace extends; a conductive plane extending adjacent the enlarged section of each of the first circuit traces; a dielectric sheet extending as a part of the daughter card between the conductive plane and each of the first circuit traces; means for connecting the conductive plane to a fixed electrical potential; and, a second row of contact pads extending along the first side of the edge portion, wherein the second row of contacts pad is disposed inwardly from the first row of contact pads, wherein individual circuit traces within the first circuit traces extend inward from the contact pads in the first row between adjacent contact pads inenlarged section of each of the first circuit traces is disposed inwardly from the second row of contact pads.
