Abstract:
1. An apparatus for establishing an electrical connection between a chip and a circuit board for testing said chip comprising: at least a tall contact, each said tall contact hinged at a first end such that it is rotatable about said first end when a force is applied at a second end, said tall contact including a first resilient member located at an intermediate point between said first and said second ends, such that said first resilient member biases a rotation of said tall contact when a force is applied at said second end; at least a short contact, each said short contact hinged at a first end such that it is rotatable about said first end when a force is applied at a second end, said short contact including a second resilient member located at an intermediate point between said first and said second ends, such that said second resilient member biases a rotation of said short contact when a force is applied at said second end; an interposer member electrically connecting said short contact to a load board terminal whereby said tall and short contact elements are electrically isolated from each other, and said second end of said tall contact and said second end of said short contact establish contact with a surface of said chip at the same time.
