Abstract

The embodiment of the invention discloses a verification method, a device, a drilling machine and a storage medium for the machining accuracy of a drilling machine. The method includes: controlling the drilling machine to drill a reference hole corresponding to the simulated value of the process test parameter on the substrate according to the simulated value of the process test parameter; the process test parameter includes at least the manufacturing error of the reference point of the reference hole, The offset error of the substrate, the rotation error of the substrate, and the expansion and contraction deformation error of the substrate; using the reference hole as a visual positioning reference, forming a secondary drilling on the substrate; measuring the hole position accuracy of the secondary drilling , if the hole position accuracy is greater than the standard threshold, it is judged that the machining accuracy of the gong drilling machine is qualified. The technical solution provided by the embodiments of the present invention can realize the verification of the processing accuracy of the low-cost, high-efficiency and highly automated gong drilling machine.

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 the machining accuracy of a drill, a drill 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 to drive the growth of the PCB industry. It is estimated that the PCB industry under the 5G outlet 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 of the 5G signal rate, the deviation of the board making has a greater impact on the signal performance, which requires stricter control of the production deviation of the b...
