Whitepaper: EMI Shielding with Coated Plastics

 

Most molded plastics designed today aren't manufactured to contain EMI. The problem is that it's difficult to get conductive closure at the seams. If the plastic enclosure isn't designed properly, radiated emissions failure is almost certain to occur. "EMI Shielding with Coated Plastics" by William D. Kimmel, PE discusses problems that could occur with EMI shielding and how to … [Read more...]
