電磁相容對於電子產品的品質相當重要，是研發時不可或缺的一個工作項目，尤其對於資訊類電子產品來說更是如此。設計良好之產品，除了可以取得各國認證，達到販售的目的外。更能夠使產品不產生大量之輻射，避免對其他電子產品造成不必要之干擾，確保電磁干擾之安全。
一般業界所用之印刷電路板，常會使用訊號線換層的佈線手法，使得訊號線能夠順利到達目的地。本論文主旨在於探討訊號線換層後，訊號之回返電流，在無法有效地找到最佳的回返路徑時，針對電磁干擾所產生之影響。以及加上適當的換層電容值後，使訊號線能夠得到較小路徑之回返電流時，其電磁輻射特性上之變化。
Electromagnetic compatibility (EMC) is an extremely critical and indispensable technology for all electronic products, espcially for information technology equipment (ITE). Products implemented with good EMC solutions can be certified and sold in different markets. Moreover, by suppressing radiation levels, interference among electronic devices can be avoided to ensure proper equipment function.
Layout design in printed circuit board usually involve changing signal lines among different layers. This thesis focuses on two aspects. First is the electromagnetic radition from astrayed returning signal current. Second is the effect of electromagnetic interference suppression of different decoupling capacitor sizes. A brief layout guideline and recommendations for the use of decoupling capacitor are drawn.
