Abstract:
A spiral contactor for establishing an electrical connection with a semiconductor device or electric part including a solder ball, the spiral contactor comprising:an insulating substrate; and a spiral probe contacting the solder ball, said spiral probe including a single spiral inwardly extending cantilevered portion having a spiral shape as viewed from a top thereof, the spirally extending cantilevered portion having a fixed proximal end and a free distal end, wherein the spiral probe is embedded in the insulating substrate in a manner that permits resilient deformation thereof in accordance with a shape of the solder ball; and wherein the spiral probe has an acute edge which is pressed so as to engage into the solder ball and slides along a periphery of the solder ball, thereby cutting oxide membrane thereon.
