Demateable, compliant, area array interconnect

A device for making electrical connections comprising:

• a carrier board having a clearance opening therein and a first and second surface;
• a first self-supporting, metallic arm attached at one end to said first surface of said carrier board, said first arm having a free end including an electrical contact surface, said first arm attached to said carrier board so that the free end is positioned over said first clearance opening;
• a second self-supporting, metallic arm attached at one end to said second surface of said carrier board, said second arm having a free end including an electrical contact surface, said second arm attached to said carrier board so that the free end is positioned over said first clearance opening;
• and
• a via between the attached ends of the first arm and the second arm.
