Abstract:
1. A vertical probe card comprising: a bottom substrate; a top substrate; an interposer disposed between the bottom substrate and the top substrate; a plurality of first electrically conductive polymer contacts disposed on the bottom substrate and opposite to the interposer; a plurality of second electrically conductive polymer contacts disposed on the top substrate and opposite to the interposer, wherein the first electrically conductive polymer contacts are arranged differently from the second electrically conductive polymer contacts, and the interposer is configured to electrically connect each first electrically conductive polymer contact and a corresponding one of the second electrically conductive polymer contacts; a first anisotropic conductive film disposed between the bottom substrate and the interposer, configured to electrically connect the bottom substrate and the interposer; and a second anisotropic conductive film disposed between the interposer and the top substrate, configured to electrically connect the interposer and the top substrate.
