Lateral interposer contact design and probe card assembly

摘要

The present invention is directed to an interposer having an interposer substrate with an upper surface and a lower surface and at least one resilient contact element having an upper portion and a lower portion. The upper portion extends in a substantially vertical fashion above the upper surface of said interposer substrate, and the lower portion extends in a substantially vertical fashion below the lower surface of said interposer substrate. The upper and lower portions of the resilient contact element are substantially resilient in a direction parallel to the substrate.
