Abstract
An electromagnetic shield system for cartridge-based printed circuit cards inserted into a printed circuit mother board comprises a card level system and a board level system which are electrically connected upon card insertion to provide more effective EMI shielding system. Prongs on a card level tab provide continuous EMI shielding even as card insertion operations are taking place. The principal linkage between the card level and board level systems is provided by a flexible shield strip which mates with apertures in a conductive board stiffener and simultaneously contacts not only a conductive cartridge bezel, but also contacts an EMI shield plate disposed on the printed circuit card.
