| Zusammenfassung: | A circuit board includes a printed substrate, a number couple of high signal transmission ports and a number of auxiliary testing ports. The couples high signal transmission ports are electrically connected to printed substrate, and each of the couples high signal transmission ports has an space smaller than 50 mil measured from the centers of the high signal transmission ports. The auxiliary testing ports respectively mounted on the high signal transmission ports, and every two testing ports mounted on a couple of high signal transmission ports are interspaced by an space larger than or equal to 70 mil. |
