Document Type and Number:
WIPO Patent Application WO/2019/178977
Kind Code:
A1
Abstract:
A method and device for tracking circuit board defects on the basis of positioning holes, and a computer apparatus, pertaining to the technical field of electronic circuits. The method comprises: determining, according to size information of a circuit board, positioning holes on the circuit board, and determining position information corresponding to each positioning hole (S210); acquiring diameter information of each positioning hole, and establishing a correspondence between the diameter information and a positioning hole drilling number (S220); generating, according to the correspondence and the position information corresponding to each positioning hole, a drilling file corresponding to the circuit board (S230); and generating, according to the drilling file, a corresponding virtual positioning hole on the circuit board, and determining, according to the virtual positioning hole, a defect position on the circuit board (S240). The technical solution resolves the issue of inefficienct defect tracking caused by manually modifying a drilling file, and automatically controls an apparatus, so as to generate positioning holes according to an actual scenario of a circuit board, thereby improving the efficiency of circuit board defect tracking.
