Abstract

The embodiment of the invention discloses a verification method and device for machining precision of a drilling and milling machine, the drilling and milling machine and a storage medium. The methodcomprises the following steps: controlling a drilling and milling machine to drill a reference hole corresponding to an analog value of a process test parameter on a substrate according to the analogvalue of the process test parameter, wherein the process test parameters at least comprise a reference point manufacturing error of the reference hole, an offset error of the substrate, a rotation error of the substrate and an expansion deformation error of the substrate; taking the reference hole as a visual positioning reference, and forming a secondary drill hole in the substrate; and measuringthe hole position precision of the secondary drilling, and if the hole position precision is larger than a standard threshold value, judging that the machining precision of the drilling and milling machine is qualified. According to the technical scheme provided by the embodiment of the invention, low-cost, high-efficiency and high-automation verification of the machining precision of the drilling and milling machine can be achieved.

Description

technical field [0001] Embodiments of the present invention relate to a printed circuit board (Printed Circuit Board, PCB) processing technology, and in particular to a method and device for verifying machining accuracy of a drilling machine, a drilling machine and a storage medium. Background technique [0002] At present, 5G is leading the trend of the Internet of Everything. In the next five years, 5G communication will surpass today's two major application markets of smart terminals and automotive electronics, and become the first engine driving the growth of the PCB industry. It is estimated that the PCB industry under the 5G trend will have several Hundreds of billions of dollars of market growth space. However, 5G also puts forward higher and stricter process requirements for PCB production. Due to the increase in the 5G signal rate, the deviation of the board manufacturing has a greater impact on the signal performance, which requires stricter control of the product...
