Patent ID: 7436194

Claim:
A probe comprising: (a) a dielectric substrate supporting an elongate conductor on a first side of said substrate and supporting a conductive member on a second side of said substrate, said conductive member including a contact surface on a side of said conductive member distal of said dielectric substrate for contacting a device under test; and (b) a contact electrically interconnected to said elongate conductor and protruding from said second side of said substrate for contacting said device under test; (c) wherein said elongate conductor and said conductive member form a controlled impedance structure; and (d) wherein said probe has a characteristic that its contact resistance when said contact is engaged with un-patterned aluminum of said device under test is generally less than 30 milliohms during any engagement of an initial 5000 engagements of said contact and said un-patterned aluminum.
