Abstract
An electromagnetic interference (EMI) gasket for an electronic module comprises a valley feature formed on one side of an EMI gasket and a crown feature formed on the other side of the EMI gasket in order to complement the valley. One or more EMI gaskets are used to construct a shield across the opening of a module cage or rack. Each gasket forms a link in a series of modules, in order to complete a seal across the opening in the cage. A perpendicular pressure forces the module gaskets to center and align evenly as the crown and valley of the opposite features nest together. The modules can be then pressed together and the overlap of the crown and valley acts to center the alignment and create a pressure for satisfactory EMI grounding and the reduction of EMI leakage.
