发明名称 Optical inspection of laser vias
摘要 An automated optical inspection system including a source of electromagnetic radiation for delivering a radiation beam on an article to be inspected, a plurality of sensors arranged with respect to the radiation beam for sensing a plurality of radiation properties associated with the radiation beam impinging at least at a zone of impingement on a substance found on the article to be inspected, the plurality of sensors including a luminescence sensor for sensing luminescence of the substance due to the beam impinging thereon and a reflectance sensor for sensing reflectance of the beam from the substance the sensors transmitting information signals based on the radiation properties sensed by the sensors and a processor in communication with the sensors operative to receive the information signals for a plurality of zones of impingement, to combine the signals from the sensors and to analyze them, and to generate an output indicating the presence of defects based on the analysis.
