Patent ID: 7528616

Claim:
A zero insertion-force interposer daughter card (IDC) for use in a test apparatus having a test socket, comprising: a test package area containing a set of test package pads for surface mounting I/O's of a test package; an extended area adjacent to the test package area having a set of replicated test pads for replicating the test package pads and for removably inserting the IDC into the test socket; and traces for coupling the test package pads to the replicated test package pads; wherein when the extended area is removably inserted into the test apparatus such that the set of replicated test pads mate with the test socket, an test socket clamp rests on the top side of the extended area to hold the IDC in place, while the test package area is left suspended in air and not disturbed by force imparted by the test socket clamp.
