The test section of the current electronic assembly industry production line can use the software control operation program for automated testing. However, since a product test often involves multiple projects, it is still necessary to conduct test-related operations through various professionals, and the current electronic The assembly line cannot integrate multiple test software, and it needs to be tested according to the process instructions. There is still inefficiency in the efficiency and labor cost. If you want to integrate multiple test software, you must develop a new test software, but the cost is increased, and its competitiveness is relatively low, which is not beneficial to the industry.

According to the results of image processing image recognition, the control terminal computer simulates sending keyboard signals to the microcontroller to control the system to be tested (PCB, printed circuit board). The test operation achieves excellent economic benefits without having to spend more time re-developing new test software.

A further objective of the present invention is to provide a software-controlled operating program to effectively simplify related detection content, speed up detection, speed up shipping time, and increase flexibility; and through modular thinking design, it will effectively solve the problem.
