<p>A probe card is provided for contacting an electronic component with raised contact elements. In particular, the present invention is useful for contacting a semiconductor wafer with resilient contact elements, such as springs. A probe card is designed to have terminals to mate with the contact elements on the wafer. In a preferred embodiment, the terminals are posts. In a preferred embodiment the terminals include a contact material suitable for repeated contacts. In one particularly preferred embodiment, a space transformer is prepared with contact posts on one side and terminals on the opposing side. An interposer with spring contacts connects a contact on the opposing side of the space transformer to a corresponding terminal on a probe card, which terminal is in turn connected to a terminal which is connectable to a test device such as a conventional tester.</p> |
