Problems solved by technology

[0003] The long production cycle of the circuit board will affect the debugging progress and delivery time of the whole machine, but it takes a lot of time to debug and detect the circuit board to eliminate hidden dangers in the production of the circuit board; the current circuit board debugging and testing are mainly through the cable The plug-in is connected to each interface of the circuit board, which has low efficiency, many hidden dangers, and the quality cannot be guaranteed. It also lacks the detection data analysis and statistical management of the circuit board batches, and cannot provide data support for the soldering and failure reasons of the circuit board. Fault analysis cannot provide help; at the same time, the traditional circuit board debugging method mainly uses human eyes to inspect the leakage of main components of the circuit board and the open and short circuits of the circuit, but this method is not only low in detection efficiency, but also labor-intensive. , error-prone, low accuracy, and unable to see the real problem in the circuit board
