Relative height adjustable connector system for motherboard to graphics board transition with a plating alternative in information handling systems

A method of operatively coupling a motherboard and a graphics board in an information handling system comprising:

• supporting the motherboard including a central processor and the graphics board including a graphics processor on a chassis, wherein the motherboard and the graphics board are coated with an anti-tarnish finish;
• plating a first interposer on at least a first side with a neutral metal material;
• soldering a first plurality of pass-through electrical contacts of the first interposer to a connector pad area of the motherboard;
• aligning a first compression jumper pad of a flexible compression jumper connector with the first plurality of pass-through electrical contacts on the plated first side of the first interposer;
• clamping the first compression jumper pad with a first fastener to compress an array of compressible communication contacts on the first compression jumper pad to the first plurality of pass-through electrical contacts on the first interposer;
• adjusting a flexible jumper trace array cable between the first compression jumper pad and a second compression jumper pad of the flexible compression jumper connector to adjacently align the motherboard and graphics board to minimize thickness of the information handling system;
• and
• operatively coupled the second compression jumper pad of the flexible compression jumper connector to the graphics board, via a second fastener, to provide lanes of data communication between the central processor and the graphics processor.

An information handling system comprising:

• a chassis supporting a motherboard having a processor and a graphics board including a graphics processor, wherein the motherboard and the graphics board are coated with an anti-tarnish material;
• a first interposer soldered to a connector pad area of the motherboard, wherein the first interposer has at least one side plated with a neutral metal material;
• a flexible compression jumper connector having a first compression jumper pad with a first array of compressible communication contacts operatively coupled to the first interposer;
• a first fastener to compress the first array of compressible communication contacts to a plurality of pass-through electrical contacts on the first interposer;
• a second fastener to compress a second array of compressible communication contacts of a second compression jumper pad to a connector pad area of the graphics board;
• and
• the flexible compression jumper connector having a flexible jumper trace array cable between the first compression jumper pad and the second compression jumper pad operatively coupled to the graphics board such that the motherboard and the graphics board are operatively coupled with lanes of data communication between the processor and the graphics processor, wherein the flexible jumper trace array cable may be adjusted to align the motherboard adjacent to the graphics board to reduce thickness of the information handling system.
