Analysis of Electromagnetic Interference Reduction from Printed Circuit Boards

 Nowadays, electricity is the most important and necessary energy in human society and daily life, because electricity is convenient and safe to transfer between different locations. However, electromagnetic interference (EMI) always accompanies electricity and has brought a lot of problems. Especially in printed circuit boards (PCB), the EMI can break the circuit or cause a short circuit, which is dangerous in creating a PCB. To effectively reduce EMI from PCB, three different methods of reducing EMI from PCB were chosen to compare with each other. By comparing their price, practicability, effectiveness, data, and technology for reducing EMI from PCB, PCB designers can choose the methods that are suitable for their situation.
