ABSTRACT:
The present invention relates to a probe for making electrical connection to a contact pad on a microelectronic device. A foot having a length, a thickness, a width, a proximal end, and a distal end, is connected to a substrate. The length of the foot is greater than its width. A torsion bar having a length, a width, a thickness, a proximal end, and a distal end, is connected to the distal end of the foot at the proximal end of torsion bar. The torsion bar lies in a first plane. A spacer having a length, a width, and a thickness, is connected to the distal end of the torsion bar. An arm having a length, a width, a thickness, a proximal end, and a distal end is connected to said spacer at the arms proximal end. The arm lies in a second plane and the second plane is in a different plane than the first plane. A first post having a top side and a bottom side is connected to the arm near the distal end of the arm. A tip is electrically connected to the top side of the post.
