Abstract: An interconnection device has a multiplicity of individual arms attached to a carrier board. The carrier board includes vias which go through the board and have a pad on the top and bottom of the board near the via. Attached to each via pad is an arm.

The amount of compliance may be 10 to 12 mils.
