Abstract

The invention relates to a circuit board tester which comprises a power module, a signal generation module, a signal distribution module, a testing module, and an indication module, wherein the power module comprises a power fuse component, a power switch component and a short circuit alarm circuit and is used for providing a stable voltage for a tested circuit board; the signal generation module comprises a signal generation component and a signal generator and is used for producing a testing signal required for the test of a data field; the signal distribution module comprises a dial switch component and is used for distributing the testing signal; the testing module comprises a testing interface circuit and measurement equipment and is used for testing the tested circuit board; the indication module comprises an indication circuit and is used for indicating input and output signals. The circuit board tester uses a shift knob, the functions are clear at a glance, the operations are simple, the modules are divided according to the functions, the same parts are combined together, so that the maintenance is facilitated; a plug-in structure is adopted, and the maintainability, the reliability and the universality are very high.

Description

technical field [0001] The invention relates to the technical field of electronic manufacturing, in particular to a circuit board tester. Background technique [0002] The circuit board is an important component in the electronic field, and the styles of the circuit board are diversified, and each circuit board has different circuits. Therefore, the circuit boards that have been produced must be strictly tested before they can be applied to various systems. [0003] Especially for ship electronic systems, there is currently no applicable testing equipment in China. In order to ensure the successful completion of the circuit board development work, and to meet the maintenance, testing and debugging of the system's faulty circuit boards, a circuit board tester must be developed by itself. Contents of the invention [0004] In order to solve the above problems, the purpose of the present invention is to provide a circuit board tester, which can complete the test of various ...
