Method and device for checking device pin connection, equipment and storage medium

Abstract

The invention belongs to the technical field of PCB wiring, and particularly provides a method, device, equipment and storage medium for checking device pin connection, and the method comprises the following steps: obtaining all devices, via holes and surface layer wires in a board and corresponding coordinate positions; determining a device to be inspected; selecting a surface layer wire passing through the via hole; checking the pins of the devices connected with the surface layer wires to determine the connected devices; checking whether the network mark number of the pin of the determined connected device is consistent with the network mark number of the determined to-be-checked device or not; if yes, whether the number of the pins of the device connected with the surface layer wire is larger than a set first threshold value or not is checked; if yes, marking pins of the device connected with the surface layer wiring; and otherwise, selecting the next surface layer wire passing through one via hole. The inspection operation is simple and convenient, missing inspection is not easy to occur, inspection of connection of a large number of pins and via holes during periods is automatically completed, and the inspection efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of PCB board wiring, and specifically provides a method, device, equipment and storage medium for checking device pin connections. Background technique [0002] The printed circuit board (Printed Circuit Board, PCB) was first used as a paper-based copper-clad printed board. Since the advent of semiconductor transistors in the 1950s, the demand for PCBs has risen dramatically. Especially the rapid development and wide application of integrated circuits. In recent years, with the development of electronic technology, in order to assemble highly integrated components, printed circuit boards have gradually become thinner and smaller. Printed circuit boards are the basic elements for improving integration. . The volume of electronic equipment is getting smaller and smaller, and the density and difficulty of circuit wiring are getting higher and higher, which requires PCB to be constantly updated. [0003] At p...

AI Technical Summary

Problems solved by technology

Take the capacitor for filtering and coupling as an example. In theory, each capacitor or resistor is designed for a via. If there are too many capacitors or resistors connected to a via, it will affect the filtering and coupling of the capacitor. , thereby affecting the signal or power supply design of the chip, thereby affecting the design quality of the product and the stability of the entire system
