Abstract
The invention provides a method of apparatus for testing circuit boards which does not require any inner wide power plane so as to detect an open circuit defect and/or a short circuit defect in a conductor path network formed in the circuit board quickly and accurately. An apparatus for testing a circuit board according to the present invention includes a transmission unit () for transmitting electromagnetic (radio) wave signal by way of an antenna () to a circuit board () to be tested, a detecting unit () for detecting signal received by a conductor path () of the circuit board () by using the conductor path () as a receiving antenna, and compare unit () for determining whether or not there is an open circuit defect or a short circuit defect in the conductor path () by comparing the detected signal with reference data of corresponding to a conductor path not including any defect.
