[0004] The application aims to solve the problem that "the existing ICT testing solutions are complex in overall structure and have many hardware requirements. They are mainly composed of industrial computers, boards, auxiliary tooling, etc., which are costly and have high requirements for on-site layout. For example, it is necessary to lay the corresponding network on site, etc., which increases the cost of use and also affects the test efficiency."

[0005] However, the current testing of PCBAs is often focused on the appearance test and performance test of PCBAs, and there are few comprehensive PCBA testing systems that combine appearance test and performance test.

[0006] Based on this, a PCBA integrated automatic testing system is proposed. Summary of the invention

The output end of the PCBA production line is connected to the input end of the ICT tester. The ICT tester uses its own clamping tooling to transport the PCBA output from the output end of the PCBA production line to the ICT tester, and is electrically connected to the ICT tester. The ICT tester simulates the PCBA operating scenario to collect the operating parameters of the PCBA in the simulated operating scenario.

[0015] Furthermore, the test module and the acquisition module run in parallel in the system;

[0016] The analysis module stores reference image data of qualified PCBAs, and performs similarity comparison based on the reference image data and the image data of the PCBA under the running state collected by the collection module to analyze whether the PCBA has appearance defects;

[0017] The similarity between the reference image data and the image data collected by the acquisition module under the PCBA running state is obtained by the following formula:

[0035] The analysis results of PCBA appearance defects are iterated with “×”, and the evaluation results of PCBA incomplete functions are iterated with “×”; the analysis results of PCBA appearance non-defective are iterated with “√”, and the evaluation results of PCBA complete functions are iterated with “√”.

[0036] Furthermore, in the queue composed of “√” and “×” obtained by iterating the symbols “√” and “×”, the queue is divided based on one or more “√” to obtain several groups of sub-queues, and each of the several groups of sub-queues only contains one or more groups of symbols “×”. The sub-queues are recorded as q1, q2, q3, etc. based on the queue sorting, and the safety of the PCBA production line is evaluated according to the changes in the sub-queues;

[0037] ;

[0038] Where: , , is the number of symbols “×” contained in each of any three consecutive sub-queues;
