ABSTRACT:
A circuit board having a board body includes a via structure. The via structure includes a conductive connector passing through the board body and a conductive shield member surrounding at least a portion of the conductive connector. The shield member prevents distortion of a data signal applied to the conductive connector, and also intercepts electromagnetic waves generated by the conductive connector.
