Problems solved by technology

At present, engineers usually design positioning holes on the physical circuit board based on the physical circuit board. When the recommended hole position is occupied, the engineer determines the position of the hole position based on his own experience. There is a risk of unreliability. At the same time, the engineer’s experience more demanding
In addition, after the engineer initially determines the hole position, he needs to conduct a reliability test, and the cycle of the reliability test is long, requiring multiple boards for testing, which increases the project cycle and development costs

Embodiment Construction

[0041] The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application. It should be noted that terms such as "first" and "second" are only used for distinguishing descriptions, and should not be understood as indicating or implying relative importance.

[0042] The applicant found that during the actual operation of the circuit board of the equipment, there is external environment interference vibration. When the vibration frequency of the interference is close to the natural frequency of the circuit board structure, resonance may occur, resulting in aggravated vibration of the circuit board structure, which is easy to cause the board not to function properly. For example, the increased vibration causes the circuit in the circuit board to become loose, and the signal cannot be transmitted normally. Therefore, the applicant found that when designing the circuit board, th...

Abstract

The invention provides a circuit board hole site determination method and device, electronic equipment and a readable storage medium, and relates to the field of structure simulation testing. The method comprises the steps of creating a finite element three-dimensional model corresponding to a to-be-tested circuit board based on geometric parameters and material parameters of the to-be-tested circuit board; according to a preset optimization algorithm, determining the number of target positioning holes and position information of all the target positioning holes in the finite element three-dimensional model from the finite element three-dimensional model, wherein the target positioning holes are positioning holes which are formed in a substrate model of the finite element three-dimensional model and enable the inherent frequency of the finite element three-dimensional model to be smaller than or equal to the preset frequency; therefore, the efficiency and the reliability of determining the positioning hole in the circuit board can be improved, a board punching test on a real circuit board is not needed, the development cost is reduced, and the project period of development and design is shortened.

Description

technical field [0001] The present application relates to the field of structural simulation testing, in particular to a method, device, electronic equipment and readable storage medium for determining hole positions on a circuit board. Background technique [0002] During the development and design process of the circuit board, the circuit board usually needs to be provided with corresponding positioning holes to fix the circuit board in the device. At present, engineers usually design positioning holes on the physical circuit board based on the physical circuit board. When the recommended hole position is occupied, the engineer determines the position of the hole position based on his own experience. There is a risk of unreliability. At the same time, the engineer’s experience Higher requirements. In addition, the engineer needs to conduct a reliability test after initially determining the hole position, and the cycle of the reliability test is long, requiring multiple bo...
