Up-to-standard detection method, system and device for circuit board wiring flux

Abstract

The invention discloses an up-to-standard detection method for circuit board wiring flux. The method comprises the following steps: acquiring wire width conditions of all wires corresponding to any wire sequence network on a circuit board; according to the wire width condition of any target wire in all the wires, calculating the maximum flux of the target wire; judging whether the maximum flux of the target wire is smaller than the corresponding wiring flux up-to-standard quantity or not; if so, determining that the flux of the target wire does not reach the standard; and if not, determining that the flux of the target wire reaches the standard. According to the invention, whether the flux of all the wires on the circuit board meets the flux requirement can be detected so that the situation that the flux of the wires does not reach the standard due to the fact that the wires are not thickened or are not thickened enough is avoided, and the design quality of the wires is improved. The invention further discloses an up-to-standard detection system and device for the wiring flux of the circuit board, and the system and device have the same beneficial effects as the up-to-standard detection method.

Description

technical field [0001] The invention relates to the field of circuit board design, in particular to a method, system and device for detecting the flow rate of circuit board wiring up to the standard. Background technique [0002] As the design space of the circuit board becomes smaller and smaller, the line width is often too thin when wiring the power supply on the circuit board. The thinner the line width, the greater the impedance of the line, which is easy to cause the flow of the line (the allowable current flow) )not to standard. At present, the wiring design on the circuit board is manually checked to determine whether the flow of the wiring is up to the standard. Specifically, after the wiring of the circuit board is completed, the designer will mark all the wiring corresponding to the same flow requirement, and screen out Lines whose flow rate does not meet the standard, and thicken the lines whose flow rate does not meet the standard, so that the flow rate can mee...

Problems solved by technology

However, there are more than one type of power supply on the circuit board, and the wire sequence networks corresponding to different power supplies generally have different requirements for the flow of wires, and the wire sequence network is spread throughout the entire circuit board, which makes it easy for manual inspection to cause trace leakage and thickening Or if the bold is not enough, it will eventually cause the flow problem or the risk of voltage drop, which will affect the quality of the wiring design
