There are many ways to solve the EMI problem. Modern EMI suppression methods include: EMI suppression coating, proper EMI suppression and EMI simulation design. This article starts with the most basic PCB layout and discusses the role and design techniques for PCB layered stacks in controlling EMI emissions.
At first glance, PCB is almost the same regardless of its internal quality. It isthrough the surface that we see differences, which are critical to thedurability and function of the PCB throughout the lifespan.
