Embodiment Construction

[0013] In order to explain in detail the technical content, structural features, achieved goals and effects of the technical solution, the following will be described in detail in conjunction with specific embodiments and accompanying drawings.

[0014] see figure 1 , a circuit board etching simulation method in this embodiment, comprising the following steps, S100 obtains a first circuit layout, the first circuit layout may be a pre-designed circuit design draft, including parameters such as layout line width, circuit The PCB plate based on the design draft will be over-etched in some cases according to the actual situation during production and processing, resulting in the problem that the quality of some products does not meet the standard. In order to give an alarm to this situation, we carry out the following steps, S102 loads the production environment parameters, simulates etching the first circuit layout according to the production environment parameters, thereby gener...

Abstract

A circuit board etching simulation method comprises the following steps that a first circuit layout is obtained, the first circuit layout comprises layout line width, production environment parametersare loaded, the first circuit layout is simulated into a production environment circuit layout according to the production environment parameters, open-circuit risk detection is carried out on the production environment circuit layout, and the open-circuit risk detection is carried out on the production environment circuit layout; when there is an open risk, a risk location is reported. Differentfrom the prior art, according to the technical scheme, the manufacturing result under the extreme environment can be simulated in simulation software, extreme conditions are avoided, so that a pre-designed circuit design draft is modified in advance, and the yield of the circuit board is improved.

Description

technical field [0001] The invention relates to the field of etching layout of circuit boards, in particular to a simulation production method of circuit boards before formal etching. Background technique [0002] The existing professional CAM software can only compare the network relationship changes between the original network of the customer file and the modified PCB film, but cannot simulate and compare the network relationship changes of the finished PCB products. Film is only a tool for PCB production, and in the process of PCB production, various comprehensive factors such as the actual etching environment and the design of the PCB itself will affect the PCB network, and even some lines with thin line widths have no problem with the network relationship. Professional Continuity test equipment can't detect it either, but it will reduce the life of the PCB. And after the PCB is produced, it is found that the problem is irreversible, which will cause losses. For examp...
