TEST METHOD, TESTING DEVICE, AND PROGRAM
Document Type and Number:
Japanese Patent JP2022189394
Kind Code:
A
Abstract:
SOLUTION: This test method includes: a measurement step in which, regarding each of some of a plurality of terminals for outputting a single-end signal and provided in the device under test, a difference value with the output value of a reference terminal which is different from the terminal is measured; and an assessment step S29 in which assessment is made as to whether or not the device under test is good, on the basis of whether or not the difference value of each of some terminals is within a first reference range. In the measurement step, the output value of each of at least one terminal among the plurality of terminals is further measured, and in the assessment step S29, assessment is further made as to whether or not the device under test is good on the basis of whether or not the output value of each of the at least one terminal is within a second reference range, and on the basis of whether or not the difference value among the output value of each of the at least one terminal is within a third reference range.EFFECT: This makes it possible to heighten the accuracy of test and shorten the test time.SELECTED DRAWING: Figure 5
