Packaging and interconnection of contact structure

A packaging and interconnection of a contact structure, comprising:

• a contact structure made of conductive material and formed on a contact substrate, said contact structure having a base portion vertically formed on said contact substrate, a horizontal portion, one end of which being formed on said base portion, and a contact portion vertically formed on another end of said horizontal portion;
• a contact trace formed on a surface of said contact substrate and electrically connected to said contact structure at one end, the other end of said contact trace being formed of a contact pad;
• a printed circuit board (PCB) pad provided on a printed circuit board (PCB) substrate positioned at an outer periphery of said contact structure;
• a double layer lead for electrically connecting a surface of the contact pad and the PCB pad;
• an elastomer provided under said contact substrate for allowing flexibility in said interconnection and packaging;
• and
• a support structure provided between said elastomer and said PCB substrate for supporting said contact structure, said contact substrate and said elastomer;
• wherein substantially all portions of said contact structure are projected from said contact substrate to a free space to allow free movements of at least said horizontal portion and said contact portion, and wherein said horizontal portion of said contact structure produces a resilient contact force when said contact structure is pressed against a contact target, thereby scrubbing a surface of the contact target.
