  • Method for measuring capacitive loads
    Patent number: 5430383
    Abstract: An automated method of verifying the capacitance loads on signal pins of an integrated circuit test load board employs a tester operating with transmission line techniques. The tester signal first is disconnected from the load board; and the rise time of the reflected waveform is measured between the ten percent and ninety percent values. The tester signal then is connected to the load board; and once again, the rise time of the reflected waveform is measured between the ten percent and ninety percent values. These two rise time values then are employed to calculate the total amount of edge loading capacitance on the path between the tester and the load board.
