发明名称 Testkarte
摘要 <p>A probe card (321) is provided for contacting an electronic component with raised contact elements. In particular, the present invention is useful for contacting a semiconductor wafer (310) with resilient contact elements (301), such as springs. A probe card (321) is designed to have terminals to mate with the contact elements on the wafer (310). 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 (324) is prepared with contact posts on one side and terminals on the opposing side. An interposer (325) with spring contacts (333, 334) connects a contact (335) on the opposing side of the space transformer (324) to a corresponding terminal (332) on a probe card (321), which terminal (332) is in turn connected to a terminal (331) which is connectable to a test device such as a conventional tester. <IMAGE></p>
