PCB 層板與EMI、EMC效應探討

從四層板推論得知，當有多於三個完整平面提供的話（即一個Power兩個ground），將最高速clock佈線於相鄰groundplane，且不相鄰於powerplane，可得最佳EMI效果，此觀念為 ...。其他文章還包含有：「BestPracticesforPowerPlanesinMulti」、「HowToImproveYourPCBLayout」、「PCB设计中为什么尽量用地平面？」、「PowerPlane」、「PowerPlanePCBBestPractices」、「PowerPlanePCB」、「WhatisPCBPowerPlane?」、「第三章量測數值...

當元件頻率越來越快，系統板頻率隨著元件增加時，常常會出現EMC問題，傳統上EMC被視為一種黑箱的藝術，實際上來說，EMC可以使用電磁學上的馬克斯威爾方程式概念來解釋，我們等一下會推導數學式來敘述幾項重要觀念。首先我們先來解釋一下EMC與EMI的定義：EMC(Electronmagneticcompatibility)電磁相容：產品能夠在一電磁環境中工作而不會降低功能或損害的能力。EMI(Electronmagneticinterference)電磁干擾：電子產品中之電磁能量經由傳導或輻射之方式傳播出去的過程。印刷電路版基本概念首先，我們先談一下印刷電路版的基本概念，當我們...
