Electromagnetic interference (EMI) in today’s electronics is tricky to address on multiple levels. It often does not present itself until late in the product’s development, and when it is discovered, the exact cause and place of origin in the PCB can be difficult to pin down.
Designers often must try every possible PCB layout, causing significant delays in production. In addition, available solutions may be too bulky for today’s shrinking electronics. As a result, EMI issues are much easier and less expensive to address in the first design stage.
This whitepaper serves as a basic introduction to successful EMI mitigation concepts and solutions. It outlines:
The Need for EMI Shielding
Common EMI Mitigation Reduction Techniques
Circuit-Level, Board-Level, and Enclosure-Level Solutions
Alternative Solutions (Surface-Mount Shielding, Grounding Contacts, and More)
