PCB centre template automatic design method and system, storage medium and terminal

Abstract

The invention provides a PCB centre template automatic design method and system, a storage medium and a terminal, and the method comprises the following steps: obtaining a PCB CAD file of a PCB, and generating auxiliary design data; judging whether the PCB is a jointed board or not based on the PCB CAD file; if yes, completing board splicing; generating a centre design file of the PCB based on a preset design rule according to the auxiliary design data; detecting whether the centre design file is qualified or not based on a preset detection rule; if not, modifying the centre design file until the centre design file is qualified; and adding auxiliary processing layer data into the qualified centre design file to generate centre template processing data. According to the PCB centre template automatic design method and system, the storage medium and the terminal, manual intervention is not needed, automatic PCB centre template design can be achieved, and practicability is high.

Description

technical field [0001] The present invention relates to the technical field of printed circuit boards (Printed Circuit Board, PCB), in particular to an automatic design method and system for a PCB thimble template, a storage medium and a terminal. Background technique [0002] Surface Mounting Technology (SMT) is a method of mounting surface mount components packaged in a matrix arrangement without leads or short leads or balls on the surface of a PCB or on the surface of other substrates, through reflow soldering or dip soldering, etc. The method is a circuit assembly technology of soldering assembly. Among them, in the process of automatic solder paste printing and placement, it is necessary to support the unprocessed surface of the PCB board with thimbles before processing. With the change of market demand and the development of science and technology, electronic products will become smaller and shorter, and the product cycle will be shorter and shorter. Not only the PCB...

AI Technical Summary

Problems solved by technology

[0007](1) The position of the thimble is judged entirely by manual or measuring tools, which takes a long time and is inaccurate. For example, for components with a height greater than amm, The thimble placement distance must be greater than bmm. Designers need to screen out devices with a height greater than amm according to the PCB design drawings, and then use measuring tools to determine the prohibited range and then arrange thimbles;

[0008](2) The experience requirements for designers are relatively high, and the thimble templates designed are thousands of people, so standardized design cannot be realized;

[0009](3) Extended product development cycle and reduced product quality
