Embodiment 1

[0044] The following introduces Embodiment 1 of a method for detecting whether the back-drilling target layer is correctly set provided by the present application, see figure 1 , embodiment one includes:

[0045] Step S101: In response to an instruction to detect the back-drilled target layer, determine the target wiring layer of the drilled hole where the back-drilled hole is located.

[0046] The purpose of this embodiment is to determine whether the back-drilling parameters are set correctly before performing the back-drilling of the physical hardware, specifically to determine whether the back-drilling target layer is set correctly.

[0047] The concepts of back-drilling, back-drilling target layer, back-drilling hole, target routing layer, and back-drilling direction that will appear below are explained below: figure 2 As shown, when making a PCB board, it is assumed that the PCB board has 10 layers, and the surface layer of one side of the PCB board needs to be equippe...

Embodiment 2

[0054] Specifically, see image 3 , embodiment two specifically includes:

[0055] Step S201: Responding to the instruction of detecting the back-drilling target layer, call the target function preset in the routing tool to obtain the drilling information of multiple drilling holes on the PCB board.

[0056] Specifically, the PCB board includes multiple drilled holes, including drilled holes that need to be back-drilled and drilled holes that do not need to be back-drilled. The above drilling information includes but is not limited to the information that all the drilling needs to be back-drilled. Therefore, in the subsequent process, the drilling that needs to be back-drilled can be screened out according to the drilling information. It should be noted that the above objective function is used to execute the entire process from step S201 to step S205. In addition, setting the objective function in the wiring tool is only a preferred implementation mode provided by this embod...

Abstract

The invention discloses a method for detecting whether a back drill target layer is correctly arranged. The method can respond to an instruction of detecting a back drill target layer. The method comprises: determining a target wiring layer of a drill hole where the back drill hole is located, and judge whether a layer adjacent to the back drill target layer in the back drill direction is the target wiring layer, if yes, the back drill target layer is judged to be set correctly, and if not, the setting error is judged to be set. Therefore, whether the back drill target layer is set correctly or not can be automatically judged according to the target routing layer, the traditional manual detection process is avoided, time and labor are saved, and the detection efficiency is remarkably improved. In addition, the invention further provides a device and equipment for detecting whether the back drill target layer is correctly arranged or not and a computer readable storage medium, and the effects of the device and equipment correspond to the effects of the method.

Description

technical field [0001] The present application relates to the field of electronics, and in particular to a method, device, equipment and computer-readable storage medium for detecting whether a back-drilling target layer is correctly set. Background technique [0002] A printed circuit board (Printed Circuit Board, PCB board) is an important part of the physical support of electronic products and signal transmission. A section of the plated through hole (PTH) in the PCB board is not used for signal transmission and is useless. The copper part of the hole will increase the loss of signal transmission in the PCB board, avoid reflection, scattering, delay, etc. of high-speed signal transmission, and destroy the integrity of signal transmission. Therefore, back drilling is often used in the industry to reduce this section of hole in PTH as much as possible. The length of the copper part, so as to reduce its influence on the signal transmission of the PCB board. [0003] The so-...
