Publication number: 20040169521Abstract: A high density probe card contact apparatus including a support block fitted into an opening in a probe card, and holding a plurality of fine tipped needles extending inward and below an opening in the center of the block. The needle tips are a noble metal integrally connected with a less costly conductive metal which forms the more widely spaced fingers of the needles, and which terminate in contacts to the probe card. Laser etching defines the fine needle pattern in a thin sheet of the two-metal composition which is secured to a polymeric film. The contact apparatus is assembled by positioning one or more sections of the polymer with needles on the support film.Type: ApplicationFiled: January 20, 2004Publication date: September 2, 2004Inventors: Reynaldo M.

Patent number: 6636063Abstract: A probe card having reliable “micro probe” contacts which include a base and an angled probe tip fabricated as a single unit from a thin sheet of a conductive metal having high tensile and yield strength, and coated with a noble metal. The micro probes are secured into precisely dimensioned, and positioned locations on the card, and are electrically connected to traces on the card. Design of the micro probes includes not only the base and probe tip, but also locking features, a stand-off to prevent over compression, and a necked down stem feature for release from the support strap used in transporting and plating during the manufacturing processes.Type: GrantFiled: October 2, 2001Date of Patent: October 21, 2003Assignee: Texas Instruments IncorporatedInventors: Richard W.

Publication number: 20030088975Abstract: A test structure that is readily and inexpensively configurable to interface with dies having different bond pad configurations is achieved by providing a blank test membrane having a conductive coating or a matrix of conductive lines formed thereon. Once a die bond pad configuration is known, the test membrane can be configured for the die bond pads by using a laser under software control to define connection pads correlating to the die bond pads and also to define interconnecting conductive traces from the connecting pads to contact pads that can be connected to test equipment. In one embodiment, the laser operates to ablate a continuous conductive coating, so as to form conductive pads and traces. In another embodiment, the laser is used to cut various lines in a matrix of conductive lines, so as to define conductive paths from the bond pads to the contact pads for connection to the test equipment.Type: ApplicationFiled: December 30, 2002Publication date: May 15, 2003Inventors: Richard W.
