Abstract:
1. A computer system board expansion housing apparatus for add-on expansion daughter board with complete EMI shield comprising: an on computer system board PCB shield zone (PCB shield zone), a metallic expansion housing cover (housing cover), and an add-on expansion daughter board, wherein, said on computer system board PCB shield zone is a copper clad ground plane PCB area fabricated on computer system board PCB as part of the computer system board PCB with solderable surrounding zone where said housing cover can be soldered on to; whereby, the non-solderable area of said copper clad ground plane of said PCB shield zone is covered with isolation means; whereby, said PCB shield zone is installed with at least one connector means for installation of said add-on expansion daughter board; whereby, said connector means providing mechanical support for attaching the said add-on expansion daughter board to said computer system board with necessary help of other mounting means; wherein, said metallic expansion housing cover is a metallic cover box with an open base that can be soldered onto the corresponding solderable surrounding zone of said PCB shield zone; whereby, after said add-on expansion daughter board is mounted onto said PCB shield zone, said housing cover is soldered onto said PCB shield zone covering said add-on expansion daughter board; and whereby, said housing cover is soldered onto said PCB shield zone forming a complete metallic shield apparatus for said add-on expansion daughter card and other electronics inside the apparatus.
