Problems solved by technology
[0004] Based on this, it is necessary to consider that when the board thickness and copper thickness of the actual printed circuit board laminate structure are quite different from those of the test board, if the hole limit obtained by common practice is still used as the processing basis, then It will cause the problem that the quality of the hole wall of the processed hole is reduced or the production cost is increased. A method and system for calculating the hole limit of printed circuit board drilling are provided.

Embodiment Construction
[0052] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.
[0053] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. In contrast, when an element is referred to as being "directly on" another element, there are no intervening ele...

The invention relates to a method and system for calculating the drilling tool life parameter of a printed-circuit board. According to the method and the system, the relation between the drilling toollife parameter S and the comprehensive hardness HPCB and the maximum abrasion loss Vmax is represented by establishing a mathematical model, wherein the comprehensive hardness HPCB can be obtained only by acquiring a corresponding parameter of a laminated structure of the printed-circuit board and performing calculation according to a formula, and the maximum abrasion loss Vmax can also be obtained through test; and then the numerical values of the comprehensive hardness HPCB and the maximum abrasion loss Vmax are substituted into the mathematical model so as to obtain the drilling tool lifeparameter S. The method and system for calculating the drilling tool life parameter of the printed-circuit board have the advantages that the drilling tool life parameter can be determined quickly andaccurately, and therefore the quality of the hole walls of machined holes can be guaranteed, in addition, the production cost can be lowered, and a great application value for actual production can be achieved.
Description
technical field [0001] The invention relates to the technical field of printed circuit board processing, in particular to a hole limit calculation method and system for drilling printed circuit boards. Background technique [0002] With the development of high-end intelligent and multi-functional electronic products, printed circuit boards (also known as PCBs) as devices and signal transmission carriers are also increasingly multi-layered and highly heat-dissipating. The number of layers, plate thickness, and copper thickness of printed circuit boards are increasing, and higher requirements are placed on the processing technology of printed circuit boards. For the drilling process of printed circuit boards, the laminated structure of printed circuit boards has a great influence on the drilling quality. Manufacturer of printed circuit boards. [0003] Generally, when determining the hole limit of drilling (also known as the drill tool life parameter, indicating the limit dr...
