The EMC Challenge: Balancing Advanced Attenuation With Cost Concerns
In a recent application at Optima EPS, An Elma Company the customer
required a minimumelectric fi eld attenuation of 60 DB of shielding
effectiveness from 100 KHZ to 1 GHZ decreasingto a minimum of 55 DB at
10 GHZ. As the enclosure was quite large (70” H by 36” D),using certain
techniques was not cost-effective. Optima’s challenge was to solve the
EMIproblem while keeping costs reasonably low.
