US 6,605,953 B2 · Method and apparatus of interconnecting with a system board

Abstract

A method and apparatus of interconnecting with a system board is presented. A system board having a metal stiffener mounted thereon is provided with an opening in the stiffener to provide access to an area of interest on the system board. A probe test assembly is positioned a the opening and secured to the stiffener when testing is desired to provide access to the pins of the device under test (e.g., a Multi Chip Module (MCM) on the system board). Alternatively, a system enhancement device, such as an MCM or Single Chip Module (SCM) having additional Central Processing Units (CPU's) or other features, may be installed on the system board at the opening in the stiffener to enhance the function of the system board. Another alternate includes an interface assembly positioned at the opening in the stiffener. A cover is positioned at the opening and secured to the stiffener at all other times.

Dependent claims

A method of testing a system board having an area of interest, comprising:

removing a cover to provide access to the area of interest on said system board;
positioning a pattern plate having a plurality of guide holes therethrough relative to the area of interest, said pattern plate comprised of an insulating material;
inserting through a desired said guide hole of said pattern plate a singnal probe to provide an electrical connection with a first signal at the area of interest;
inserting through another desired said guide hole of said pattern plate a ground probe to provide an electrical connection with a ground at the area of interest, said ground probe being electrically coupled with said signal probe to provide a return ground path;
connecting said probe to an external device for testing of said first signal;
and
replacing said cover to prohibit access to the area of interest on said system board after testing is completed.
