Probe Test Card with Flexible Interconnect Structure
First Claim
1. A probe test card assembly comprising:
- a printed circuit board having a plurality of electrical contacts disposed thereon;
a space transformer having a first plurality of electrical contacts disposed thereon for providing electrical connections with the plurality of electrical contacts disposed on the printed circuit board and a second plurality of electrical contacts for making contact with a plurality of test probes;
a probe head structure supporting the plurality of test probes, each test probe in the plurality of test probes having a first end for making electrical contact with a device under test and a second end for making electrical contact with one of the electrical contacts from the second plurality of electrical contacts on the space transformer; and
a flexible interconnect structure connected to the first plurality of electrical contacts on the space transformer and to the plurality of electrical contacts on the printed circuit board for providing electrical contact between the first plurality of electrical contacts on the space transformer and the plurality of electrical contacts on the printed circuit board.

Abstract
A probe test card assembly for testing of a device under test includes a printed circuit board (PCB), a space transformer, a probe head structure and a flexible interconnect structure. The space transformer has a first plurality of electrical contacts disposed thereon for providing electrical connections with a plurality of contacts disposed on the PCB and a second plurality of electrical contacts disposed thereon for making contact with a plurality of test probes. Each test probe from the plurality of test probes has a first end for making electrical contact with a device under test and a second end for making electrical contact with one of the electrical contacts from the second plurality of electrical contacts on the space transformer. The flexible interconnect structure provides electrical connections between the first plurality of electrical contacts on the space transformer and the plurality of electrical contacts on the PCB.
