EMI Shielding Techniques In RF Circuit Boards

Any electronic device you design must be compliant with EMI standards set by regulatory boards like CISPR, FCC, or IEC. So, how do designers ensure that EMI standards are met? 

Creating products that meet EMI standards begins during the design phase. During this process, various measures—such as the proper placement of components, avoiding sharp bends, and grounding planes—are put in place to reduce EMI. In the final stages of product development, EMI testing is carried out to check whether the EMI of the product is within acceptable limits. 

To ensure EMI standards are met, different EMI shielding techniques can be used. In this article, we will discuss some common EMI shielding techniques and future trends in the field.
