Embodiment Construction

[0030] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0031] As shown in Figure 1, the present invention fixes the circuit board to be tested by a test fixture, and the test fixture includes a test seat and test pins, and the test seat is used to carry the circuit board to be tested, and the number and distribution of the test pins are based on the circuit to be tested. For example, confirm that the hardware interfaces to be tested on the circuit board to be tested include external interfaces, program download interfaces, power interfaces, and reset interfaces. Then customize the test fixture so that the test pins correspond to the pins of each interface one by one and can be fully contacted during the test, so that the damage of the interface pins can be avoided. The test fixture can also add ammeters, power switches, buttons, indicator lights, etc. according to its own needs.

Abstract

The invention discloses a test system of circuit board and a relative method. The test system comprises a test clamp, a test circuit board and a display terminal, wherein the test clamp is used to fix an object circuit board and provided with a plurality of test pins connected with the test points of the test items of the object circuit board, the test circuit board is provided with a microcontroller, the microcontroller is used to control the test circuit board to provide a test signal to reach the object circuit board via the test pins on the test clamp and obtain the feedback test data to analyze test result which is displayed on the display terminal. The test method comprises using the test system to test an object circuit board. The invention builds an intelligent test platform which can quickly test circuit board. The invention with a view to hardware problem can improve circuit board test efficiency.

Description

technical field [0001] The invention relates to a circuit board testing system and method. Background technique [0002] With the rapid development of the electronics industry, more and more devices tend to develop in the direction of high integration and small size, which puts forward high requirements for large-scale chip welding technology. Such high requirements of welding technology inevitably make False soldering and short circuit occur during the soldering process, so this requires inspection of the soldered circuit board. However, for a circuit board with tens of thousands of components, it is very difficult for technicians to troubleshoot problems piece by piece based on their experience. Especially in the process of mass production of circuit boards, the detection of circuit boards is very detailed and cumbersome, and this manual detection method is even more inefficient. Contents of the invention [0003] The technical problem to be solved by the present inven...
