Abstract

An EMI/RFI shield assembly for shielding printed circuit board components, including a frame affixed to the PCB, and a lid connected to the frame. The frame sidewalls each have top and bottom portions. Each bottom portion includes formed series of crenels and merlons. The crenels have a termination edge disposed a predetermined distance from the merlons. The lid includes a cover wall portion and engagement elements extending therefrom such that at least one of the engagement elements is associated with each sidewall. Each engagement element includes a surface for connection with the frame at the upper terminating edge of one of the crenels, whereby said lid is biased toward the frame compensating for tolerance stack-up.
