Problems solved by technology

However, the accuracy of test point recognition in this way depends entirely on the technical level of the technicians, and there are prone to problems such as missed detection and multiple detections, and this recognition method also requires too much energy of the technicians
Of course, some PCB engineering file test point analysis tools can automatically analyze test points, but there are often many unnecessary test points in the test points analyzed by these analysis tools. These unnecessary test points lead to low efficiency of PCB testing, and then affect overall productivity

Abstract

The present application proposes a test point identification method, device and application, including the following steps: acquiring basic PCB primitives, constructing a network connectivity graph based on the PCB basic primitives, selecting any network node in the network connectivity graph as an execution node, The execution node is the starting point to travel the network connectivity graph. During the travel process, the traveled network nodes are marked as traveled nodes, and the traveled network line segments are marked as traveled line segments, and the network line segments that connect the traveled nodes are collected as The subset of traveled nodes counts the number of network line segments in the subset of traveled nodes. If the number of line segments is 1, the traveled node is identified as a test point, and the number of network line segments is used to determine whether the network node must be tested. Network nodes, and then screen necessary test points among many network nodes, reduce the test of unnecessary test points, and improve the efficiency of PCB testing.

Description

technical field [0001] The present application relates to the field of printed circuit boards, and in particular, to a test point identification method, device and application. Background technique [0002] The parts on the PCB are complex and diverse. If they do not meet the process requirements, they cannot be manufactured rashly. Therefore, they need to be tested before the PCB is manufactured. In order to test the PCB, it is necessary to set test points on the PCB. In other words, the purpose of the test points on the PCB is to test whether the components on the circuit board meet the specifications and solderability. [0003] In the prior art, test points are manually selected on the PCB, and the selected test points are sent to the corresponding test equipment, so that the test equipment can perform a connectivity test on the PCB according to the selected test points. However, the accuracy of test point identification in this way is completely dependent on the technic...
