Problems solved by technology

Assuming that each test program that executes the parallel test can independently control the test resource, the following situation will occur: test program 1 sets a certain test resource to an output state, and at this time test program 2 executes an initialization action on the test resource, all The settings are restored to the default state and the output of the test resource is still connected to the object under test. The result at this time is that the test result of test program 1 is not credible (the faulty part is judged as a qualified part, or the qualified part is judged as a faulty part. parts); in severe cases, damage to the object under test or the test system

Abstract

The application provides a system capable of realizing parallel testing of a circuit board, which comprises a plurality of circuit board patch panels, a test adapter and a test module, wherein the circuit board patch panels are used for connecting the circuit board to be tested and carrying out signal extraction and conversion; the test adapter is connected with the circuit board patch panels; and the test module comprises a plurality of test resources and is connected with the test adapter through an array interface.

Description

technical field [0001] The invention relates to the field of automatic testing, and more specifically, the invention relates to an automatic testing system and method for realizing parallel testing of circuit boards. Background technique [0002] In the mid-to-late 1990s, under the unified coordination of the U.S. Department of Defense Automatic Test System Executive Office (DoD ATS EAO), the U.S. Army, Navy, Air Force, Marine Corps and the industry jointly launched the next-generation automatic testing system named "NxTest". Research work on test systems, in which parallel test technology is listed as one of the main key technologies. [0003] Parallel testing means that the automatic test system (ATS for short) performs multi-channel measurement on a measured object at the same time, or measures multiple measured objects at the same time. The purpose of parallel testing is to improve the testing efficiency of ATS and reduce the testing cost. [0004] Although the existin...
