ABSTRACT:
A board adapter for electrically connecting an electrical card connector to a mother board, comprises 68 signal holes, 100 conductive pads, a plurality of signal traces, a first grounding means, a transforming unit and a second grounding contact. The first grounding contact surrounds the signal holes and is electrically connected with a corresponding grounding contact of the electrical connector, for providing the signal holes and the electrical connector with grounding protection. The second grounding contact is alternately juxtaposed with every two of the signal traces for providing grounding protection. The conductive pads are electrically connected with either the signal traces or the grounding contacts. The transforming unit includes two power traces to separately bear two different strength voltage induced currents. When either of the traces bears a corresponding voltage induced current, the other trace can be transformed into a grounding trace to protect the bearing trace.
