Description

[0002] In electronic manufacturing industry, circuit board as the basic component of electronic equipment, its welding quality is directly related to the performance and reliability of the entire equipment. Especially in high-precision electronic equipment, circuit board is welded with rows of wires, and the welding ends of these wires need to keep the same length reserved to ensure the stability of circuit connection and the accuracy of signal transmission. This requirement is crucial to improve product quality and yield.

[0003] However, the traditional circuit board welding quality detection method mainly relies on human meticulous detection. Since the number of wires on the circuit board is numerous and closely arranged, the detection personnel need to measure each wire one by one to verify whether the reserved length of its welding end meets the design requirements. This detection method not only consumes time and effort, but also is easily affected by human factors, making it difficult to guarantee the detection efficiency and accuracy. More seriously, the lack of corresponding detection tools makes this detection process particularly tedious and complex. Without special detection tools, detection personnel can only rely on simple measuring tools (such as vernier caliper) to measure point by point, which not only increases the labor intensity and time cost of detection work, but also limits the improvement of production efficiency.
