Beschreibung
Zusammenfassung:	A circuit board includes a carrier, a patterned metal layer, a solder resist layer and a mark, the patterned metal layer is disposed on a surface of the carrier and includes circuit lines, the solder resist layer covers each of the circuit lines except a line fragment of each of the circuit lines. The line fragment of each of the circuit lines passes through a probe moving region which is used to determine moving path of a probe card on the carrier such that probe of the moving probe card is able to touch the line fragment of each of the circuit lines sequentially. The mark has an identification edge provided for checking the probe moving region so as to prevent deviation of the moving probe card from the probe moving region.
