Method for testing printed circuit boards

Abstract

The invention discloses a method for testing printed circuit boards. The method includes electrifying the printed circuit boards and reading numerical values of test items in memories when the printed circuit boards are in test modes; judging whether the numerical values of the test items are equal to preset test numerical values or not and acquiring judgment results; judging whether the numerical values of the failed test items are zero or not if the judgment results indicate that the numerical values of the test items are equal to the preset test numerical values; displaying success of previous tests via displays if the numerical values of the failed test items are zero; displaying the numerical values of the successful test items, the numerical values of failed tests and serial numbers of the failed test items via the displays if the numerical values of the failed test items are not zero. The method has the technical advantages that technical problems of complexity of test procedures and unclear test result records when various function modules of PCBA (printed circuit board assemblies) are tested in the prior art can be solved; various function modules on the printed circuit boards can be conveniently and accurately tested by the aid of the method, and test results can be accurately stored and displayed.

Description

technical field [0001] The invention relates to the technical field of printed circuit boards, in particular to a method for testing printed circuit boards. Background technique [0002] In the production process of electronic products, it is necessary to download software and perform functional tests on the PCBA (printed circuit board assembled with electronic components) to ensure that the functions of electronic products are all normal. [0003] In the traditional test method, in each process of a large number of PCBAs, whether each functional module is qualified or not is recorded in the form of label paper, and the pasting of the label paper cannot find a suitable position for the compact PCB board. , the size of the label paper itself is limited and it is impossible to record all the faults of the PCBA, and the label paper will fall off during the PCBA circulation process, making it impossible to judge the status of the PCBA in the next process. It is necessary to test...
