ABSTRACT:
A field hardened industrial device is described with a housing of the device having electrically conductive walls surrounding a cavity with an open end. An electronics assembly is adapted to fit within the cavity. The device includes a circuit card assembly, which is a multi-layered printed wiring board with pass-through electrical connections and an embedded ground plane electrically coupled to the housing to shield the electronics assembly from electromagnetic interference and to provide environmental protection to the electronics assembly.
