ABSTRACT:
An integrated electromagnetic and radio frequency interference (EMI/RFI) shielding apparatus contains EMI/RFI produced by a computer system. In particular the apparatus isolates input/output (I/O) connectors of the computer system from EMI/RFI produced by noisy components of the system. The shielding apparatus comprises a printed circuit board (PCB) partitioned into two electromagnetically isolated zones separated by a non-conducting void. Components that are EMI/RFI producers, such as the CPU and clock, are mounted in a first zone, and components which need to be isolated, such as input/output connectors are mounted in a second zone. The various conducting layers in the PCB are arranged and filtered to inhibit EMI/RFI propagation to the I/O connectors. Additionally, the I/O connectors are isolated from EMI/RFI by a secondary EMI/RFI shield.
