  • Circuit board testing method
    Patent number: 5977776
    Abstract: The invention relates to a circuit board testing method, wherein an array of several circuits of a circuit board are short-circuited and further circuits are short-circuit tested by applying a high test voltage relative to said array of circuits, as a result of which the number of tests, which are normally highly time-intensive due to the high voltages, is drastically reduced since the further circuits do not need to be tested discretely relative to each circuit of the circuit array.
