【摘要】：在電子產(chǎn)品設(shè)備高度發(fā)展的今天，，人們對電子設(shè)備的工作穩(wěn)定性等也有了更高的要求。在設(shè)計電子設(shè)備時，電磁兼容問題不容忽視，良好的電磁兼容性是設(shè)備正常運作的保障。如果產(chǎn)品成型之后再發(fā)現(xiàn)電磁兼容問題并設(shè)法解決，在理論和實際上都將十分困難。所以在產(chǎn)品成型之前如果能很好的解決設(shè)備的電磁兼容問題無疑會節(jié)省很多時間和精力，因而對電子設(shè)備的PCB板即印刷電路板進行電磁兼容分析具有重要的研究意義。 論文首先介紹了PCB板的設(shè)計并討論了電路板電磁兼容問題的基本理論，闡述了印刷電路板出現(xiàn)電磁兼容性問題的原因，并進行了理論研究。在南昌路通高新技術(shù)有限責(zé)任公司參與項目并研究設(shè)計出用于收發(fā)鐵路信號的嵌入式Modem，給出了設(shè)計方法以及系統(tǒng)的軟件組成，并在此基礎(chǔ)上對其進行了PCB板電磁兼容分析。針對PCB板中的電磁兼容問題，論文還創(chuàng)新的使用Mentor Graphics公司的Hyperlynx軟件對該嵌入式Modem進行建模仿真，成功的詳細分析了PCB主要存在的電磁兼容問題，并且針對典型的時鐘晶振網(wǎng)絡(luò)干擾和線間串?dāng)_這兩大電磁兼容問題提出了合理有效的解決辦法，由此總結(jié)提出了一些用于PCB板電磁兼容設(shè)計的原則。提出的解決辦法均使用軟件輔助仿真進行驗證，得出了合理正確的結(jié)論，并且在公司產(chǎn)品成型實際使用時，達到了預(yù)期的效果。
[Abstract]:With the high development of electronic equipment, people have higher requirements for the stability of electronic equipment. When designing electronic equipment, the problem of EMC can not be ignored. Good EMC is the guarantee of the normal operation of the equipment. If the EMC problem is discovered after the product is formed and solved, It will be very difficult both in theory and in practice. So if you can solve the EMC problem of the equipment before the product is formed, it will undoubtedly save a lot of time and effort. Therefore, it is of great significance to analyze the electromagnetic compatibility of the PCB board of electronic equipment, that is, printed circuit board. Firstly, the paper introduces the design of PCB board, discusses the basic theory of EMC of PCB, and explains the reason of EMC problem in PCB. In the project of Nanchang Lutong High-tech Co., Ltd., the embedded Modemon used to receive and receive railway signals is designed and designed. The design method and the software composition of the system are given. On this basis, the electromagnetic compatibility of PCB board is analyzed. Aiming at the problem of EMC in PCB board, the paper also innovatively uses the Hyperlynx software of Mentor Graphics to model and simulate the embedded Modem. The main EMC problems in PCB are analyzed in detail, and a reasonable and effective solution to the two EMC problems, which are typical clock crystal network interference and inter-line crosstalk, is put forward. Some principles used in EMC design of PCB board are summarized and put forward. The proposed solutions are verified by software aided simulation, and a reasonable and correct conclusion is drawn, and when the products are actually used in the company, The expected effect has been achieved.
