Abstract: An assembled capacitor polarity automatic inspecting method and system is proposed, which is designed for use to perform an automatic inspecting procedure to check whether an array of polarized capacitor are mounted correctly in polarity on a circuit board; and which is characterized by the use of computerized technology to automatically check whether each assembled capacitor on the circuit board is mounted correctly in polarity and automatically generate an inspection report in electronic form to show the result of inspection. This feature allows the QA/QC procedure on the circuit board not only to save labor and time but also to be much more accurate and efficient than the prior art.

Abstract: A circuit board characteristic impedance inspection method and apparatus is proposed, which is designed for inspecting the characteristic impedance of a circuit board, and which is characterized by the provision of a set of measurement contact points on the circuit board so that during actual inspection, a set of probes can be attached to these measurement contact points for an impedance measurement instrument to measure the characteristic impedance of the circuit board, and then the measured characteristic impedance is compared against a specification value to check if the characteristic impedance meets requirements. This feature allows the manufacturer to conveniently and efficiently inspect whether each manufacturer circuit meets customer-specified requirement in characteristic impedance, and therefore ensures each manufactured circuit board to be reliable to use and quality-assured for shipment to the customer.
