Abstract

Various EMI shields with thermal management capabilities are disclosed. In one aspect, an EMI shield is provided that includes a thermal spreader plate adapted to be seated on and convey heat from an electromagnetic emissions generating component. The thermal spreader plate has a first material composition and a shield effectiveness that is absorption dominant to electromagnetic waves at a given electromagnetic emissions frequency. The EMI shield also includes a shell to cover and reflect electromagnetic emissions from the electromagnetic emissions generating component. The shell has a second material composition different than the first material composition and a shield effectiveness that is reflection dominant to electromagnetic waves at the given electromagnetic emissions frequency.
