An Investigation of the Shielding Performance of PCB-level Enclosures using a Reverberation Chamber

Correlating the high-frequency shielding performance of ‘on-board’ gaskets when characterized using a stripline or reverberation room method

“…In [10], it is proven based on reverberation chamber theory that this definition is equal to the ratio of the mean received power by the source on the PCB in the unshielded and shielded case:…”

“…In [10], a reverberation room method was proposed to characterize on-board enclosures. Due to the similar nature of on-board enclosures and gaskets for on-board applications, the same method can also be applied for the characterization of gaskets.…”

“…A second method that was recently proposed is the reverberation room method proposed in [10]. In [10], it was also argued that for on-board shielding applications an appropriate definition for the shielding performance or shielding effectiveness is required.…”

“…In [10], it was also argued that for on-board shielding applications an appropriate definition for the shielding performance or shielding effectiveness is required. It was shown that the ratio of the average transmitted or received power with and without the on-board shielding is the most meaningful definition.…”

An Experimental Study of the Variability of the Shielding Effectiveness of Circuit Board Shields

“…Various techniques for examining the performance of board level shields have been described previously, for example in [1], [2], [3]. A number of techniques for the definition of and the measurement of the shielding effectiveness (SE) of these shields is under examination in the IEEE collaborative project P2716 Guide for the Characterization of the Effectiveness of Printed Circuit Board Level Shielding [4].…”
