【摘要】：科技飛速發(fā)展,市場競爭激烈,各類電子產(chǎn)品從設(shè)計(jì)到面世的周期越來越短,這就對(duì)設(shè)計(jì)和生產(chǎn)的一次性成功率提出了很高的要求。怎樣使設(shè)計(jì)更合理?怎樣使生產(chǎn)更順利?這使得可制造性設(shè)計(jì)DFM(Design For Manufacturability)的理念和重要性日益突出。而現(xiàn)有的幾款電子自動(dòng)化設(shè)計(jì)EDA(Electronic Design Automatic)軟件對(duì)DFM這一塊考慮不夠,DFM對(duì)設(shè)計(jì)人員的要求很高,幾乎全憑設(shè)計(jì)人員對(duì)生產(chǎn)制造的理解和經(jīng)驗(yàn),或者需要依賴其他的DFM專業(yè)軟件才能在設(shè)計(jì)階段防止各種DFM問題的發(fā)生。本文利用現(xiàn)有的電子設(shè)計(jì)自動(dòng)化軟件,設(shè)計(jì)印刷線路板時(shí),研究開發(fā)一些功能,使得在設(shè)計(jì)印刷線路板階段就綜合考量可制造性因素,這樣避免產(chǎn)品的某些可制造性問題直到生產(chǎn)階段才暴露。本文從絲印、測試點(diǎn)等方面切入,利用Cadence自帶的Skill語言開發(fā)相應(yīng)的DFM功能軟件,用Notepad++文本編輯器編輯整理程序,然后導(dǎo)入Allegro軟件測試其功能并優(yōu)化。實(shí)際應(yīng)用效果表明,本文開發(fā)的DFM功能軟件能較大程度地提高產(chǎn)品的合格率和生產(chǎn)效率,為生產(chǎn)制造商帶來可觀的收益。
[Abstract]:With the rapid development of science and technology and the fierce competition in the market, the period from design to appearance of all kinds of electronic products is getting shorter and shorter, which puts forward high requirements for the one-off success rate of design and production. How to make the design more reasonable? How to make production more smooth? This makes the concept and importance of manufacturability design DFM (Design For Manufacturability) more and more prominent. However, the existing EDA (Electronic Design Automatic) software for electronic automation design does not give enough consideration to this piece of DFM. DFM has high requirements for designers, and almost all depends on the designers' understanding and experience in production and manufacturing. Or need to rely on other DFM professional software to prevent various DFM problems in the design phase. In this paper, using the existing electronic design automation software, when designing printed circuit board, some functions are researched and developed, so that in the stage of designing printed circuit board, the manufacturability factors can be considered synthetically. This prevents some manufacturing problems from being exposed until the production stage. In this paper, from the aspects of screen printing and test points, the corresponding DFM function software is developed by using the Skill language of Cadence, and the Notepad text editor is used to edit the finishing program, and then import the Allegro software to test its function and optimize it. The practical application results show that the DFM function software developed in this paper can improve the qualified rate and production efficiency of the product to a large extent and bring considerable profit to the manufacturer.
