PCI Gasket System. The second EMI solution has been developed for traditional PCI and uses a bevelled face-plate and spring finger or compressible gasket. Such a system gives a robust EMI solution for applications that have restricted face plate area for all scenarios allowed by the X2 mechanical tolerance stack up. FIG 4. PCI / LO - PAK GASKET FIG 5.
