Abstract

1. TECHNICAL FIELD OF THE INVENTION

The present invention relates to an automatic test apparatus and a method for automatically diagnosing an error on a module under test.

2. The technical problem to be solved by the invention

The present invention provides an automatic test apparatus and method for automatically diagnosing an error for a module under test using a power test fixture.

3. Solution Summary of the Invention

If the unique number of the module under test and the short-circuit state of the power input terminal are normal by selecting a diagnostic test module, supply power to the diagnostic test module and perform a power test fixture search mode to use the power test fixture. In case of detection, error message is displayed to replace the corresponding parts.

4. Important uses of the invention

It is used in the automatic test equipment for automatically diagnosing errors on various modules under test.

Claims (3)

An automatic test apparatus for automatically diagnosing an error for a module under test divided into functional units by using a power test fixture, comprising a display unit and an automatic test program. A computer controlling the overall operation of checking for the presence of an error; A power supply tester for measuring various electrical characteristics of a predicted failure part in the module under test under the control of the computer; And a power test fixture for providing electrical connection by mechanical contact to each part between the power tester and the diagnostic test module. The apparatus of claim 1, wherein the computer controls the power tester to perform an automatic test on the diagnostic test module and respond to a selection of a power test fixture detection mode when an error is detected, thereby predicting a failure in the module under test. Automatic test apparatus, characterized in that by measuring the component as the power tester to detect the presence of abnormality, and to display the detection result on the display. In the automatic test method of the automatic test apparatus for automatically diagnosing an error about various modules under test by functional unit using a power test fixture, the diagnostic test module responds after selecting the power test fixture search mode. Checking whether it is inserted into the power test fixture; If the module under test is inserted into the power test fixture during the inspection, diagnosing whether the unique number of the module under test is normal and whether the power input terminal is short-circuited; Displaying a short circuit error message of a power input terminal in the module under test when an error is detected in the diagnosis process; Performing a selective function test to detect whether or not an abnormality of the module under test is detected by using a power test fixture to predict a failure part and detecting an abnormality; The automatic test method, characterized in that the process of displaying a selection error message when the error is detected in the failure detection process. ※ Note: The disclosure is based on the initial application.
