Calibration assisting device, correction method, inspection method and verification method

Abstract

The invention provides a calibration assisting device, a correction method, an inspection method and a verification method. The calibration assisting device is used for calibrating a piece of equipment adopting an automatic graphics grabbing device to carry out automatic positioning and automatic processing. The calibration assisting device comprises a bottom plate on which a first marker and a second marker are arranged. The first marker includes a first graphics identifier, and the second marker includes a second graphics identifier. The center of the circumcircle of the second graphics identifier and the center of the circumcircle of the first graphics identifier do not overlap. The calibration assisting device provided by the invention is simple to manufacture, low in cost, simple and convenient to operate, and high in calibration speed, can regularly calibrate equipment according to the actual workload, and can reduce the non-operation rate of enterprises and improve the enterprise efficiency.

Description

technical field [0001] The invention relates to the field of printed circuit board production and manufacturing, in particular to a calibration auxiliary device, a calibration method using the device, a testing method and a calibration method. Background technique [0002] At present, in the PCB industry, the development trend of multilayer printed circuit boards is unstoppable, and the requirements for the accuracy and density of its circuits are getting higher and higher. Usually, the holes on the circuit board can be divided into: positioning holes, pipe position holes, explosion-proof holes, screw holes, crimping holes, stamp holes, etc. according to their different functions. The role of the positioning holes is to better assist the pressing process. Align the layers to prepare for the subsequent process and improve the alignment accuracy between layers. In the preparation process of multilayer printed circuit boards, drilling is a critical step in the process, which h...

Problems solved by technology

However, both the punching machine and the CCD shooting machine for punching have the same problem: after every 10,000-12,000 holes are punched, the punching accuracy needs to be corrected

[0007] 1. The purchase cost and service of professional electronic calibration instruments are too high, and it is not practical for PCB manufacturers to purchase such instruments by themselves;

[0008] 2. Delay in production time. Once the punching life is reached, it will be shut down for 8-24 hours, waiting for the equipment manufacturer to correct the equipment.
