PCB drilling program automatic generation method and device, equipment and storage medium

Abstract

The invention relates to a PCB drilling program automatic generation method and device, equipment and a storage medium. The PCB drilling program automatic generation method comprises the following steps: obtaining actual target hole parameters of PCBs of the same batch after a first layer is drilled; according to the actual target hole parameters and preset target hole parameters corresponding to the actual target hole parameters, determining drilling expansion and shrinkage values of the same batch of PCBs; and obtaining product attribute information of the same batch of PCBs, and determining and executing drilling programs of other layers of the PCBs according to the drilling expansion and shrinkage value. The invention provides a PCB drilling program automatic generation method and device, equipment and a storage medium. The invention includes comparing actual parameters of the first layer of drilling holes of the PCB with preset standard parameters of the layer of holes through actual measurement targeting equipment to determine an expansion and shrinkage value; calling out drilling programs of to-be-drilled holes in other layers corresponding to the batch of boards from the database; and performing targeted drilling after adjustment is performed according to the expansion and shrinkage value, so that the adaptability of the expansion and shrinkage condition is improved, and the productivity of a production line is improved.

Description

technical field [0001] The invention relates to the technical field of electronic circuit board production, in particular to a method, device, equipment and storage medium for automatically generating a PCB drilling program. Background technique [0002] HDI is the abbreviation of High Density Interconnector. It is a technology for producing printed circuit boards. HDI boards are circuit boards with relatively high circuit distribution density using micro-blind buried hole technology. In the HDI board production process, the traditional drilling program generation method is as follows: After each pressing of the HDI board, use the CCD of the X-RAY equipment to identify the inner layer or the sub-outer layer pattern, and the target hole will be drilled in the way of seeing the target. play out. [0003] In the above process, due to factors such as film expansion and contraction in the previous process, DES line etching residual copper, static time, high temperature and low t...
