PROBE CARD FOR FINE PITCH CIRCUIT PROBE TESTING OF SEMICONDUCTOR INTEGRATED CIRCUIT DEVICES AND METHODS OF FORMING THE SAME
A probe card for use in circuit probe testing and methods of fabrication thereof. The probe card includes a circuit board, an interposer structure that is mounted to the circuit board, and a probe structure mounted to the interposer structure and including a probe substrate, a redistribution layer over the probe substrate, and a plurality of probe pins over the redistribution layer. The interposer structure may include a plurality of elastically-deformable interposer pins electrically connecting the circuit board to the probe substrate. The center-to-center spacing (i.e., pin pitch) between the interposer pins may be greater than the center-to-center spacing (i.e., a second pin pitch) between the probe pins. A probe card in accordance with various embodiments may enable circuit probe testing of a device-under-test with a pitch between adjacent probe pins that is less than 50 ?m.
Contact terminal, inspection jig, and inspection apparatus
A contact terminal includes a tubular body and a first conductor. The tubular body has an end-side cutout provided in a shape cut out from one axial-direction end surface toward an other axial-direction side at one axial-direction end portion of the tubular body, a hole that is open at the one axial-direction end portion, and a pair of arms interposed between the end-side cutout and the hole. The first conductor includes a first insertion including an inclined portion having an outside diameter gradually increased toward one axial-direction side, and a first straight portion connected to the one axial-direction side of the inclined portion and having an outside diameter constant along the axial direction. The outside diameter of the first straight portion is larger than an inside diameter of the tubular body. The first straight portion is configured to be in contact with the pair of arms.
Contact tip and contact element and method of producing the same
A contact tip for a sequential test of electronic components comprises a base material and a hard material, wherein the base material and the hard material are fixed to each other and wherein the hard material has a thickness of at least 0.03 mm. The contact tip may be the contact tip of a contact element used for a sequential test of electronic components. A method of producing a contact tip of a contact element used for a sequential test of electronic components, comprises: Providing a plate made up of a base material and a hard material, wherein the base material and the hard material are fixed to each other; Cutting the plate along a cut line to form the contact tip wherein the cut line runs through the base material and the hard material and wherein the hard material has a thickness of at least 0.03 mm in a section where the cut line cuts the hard material.

CATHETER WITH COMPOSITE INSERT SUPPORT MEMBER
An irrigated electrophysiology catheter has a tip electrode having a shell, and a support member configured to plug the shell and support one or more tip components and/or facilitate their functions. Advantageously, the support member has an electrically-conductive interface portion and an insert-molded portion, wherein the interface portion, typically constructed of a precious metal alloy, is structurally minimized, yet still configured for electrical connection with the shell and the lead wire, so as to reduce the amount and hence the cost of its manufacture, whereas the insert-molded portion is constructed of a significantly less-costly material and is readily configured with micro-complex 3-D geometry adapted to support tip structure and functions including irrigation, force sensing and temperature sensing, as a further cost savings in the manufacturing of the tip electrode by reducing materials, labor and time.
MULTI-TEST TYPE PROBE CARD AND CORRESPONDING TESTING SYSTEM FOR PARALLEL TESTING OF DIES VIA MULTIPLE TEST SITES
A probe card for testing dies of a substrate during a wafer sort process includes a printed circuit board (PCB) and a test site arranged to connect respectively to one of the dies during a test cycle. The test site includes a first pin connecting band and a first pin set. The first pin connecting band is connected to the PCB. The first pin set is connected to the first pin connecting band and includes a pin configuration for a testing device to perform a first type of test on a first die. The test site includes only pins in the first pin set. A number of pins in the first pin set is less than a number of pins used to perform a second type of test on the first die. The second type of test is performed at a slower processing speed than the first type of test.
WIRED RUBBER CONTACT AND METHOD OF MANUFACTURING THE SAME
A wired rubber contact including a lower film, an upper film, a plurality of conductive wires, a rubber layer, and a film guide. The lower film includes a plurality of lower electrode parts formed in openings. A periphery of the upper film is disposed within an interface between the central area and the peripheral area. The conductive wires are disposed between the lower film and the upper film, and connect between the lower electrode parts and the upper electrode parts. The rubber layer includes elastic material. A periphery of the rubber layer is protruded toward an outer side from the periphery of the upper film. The rubber layer maintains a constant distance between the lower film and the upper film. The film guide is disposed in the peripheral area of the lower film along a side surface of the rubber layer and integrally formed with the lower film.

Method of manufacturing implantable wireless sensor for pressure measurement
A method of manufacturing a sensor for in vivo applications includes the steps of providing two wafers of an electrically insulating material. A recess is formed in the first wafer, and a capacitor plate is formed in the recess of the first wafer. A second capacitor plate is formed in a corresponding region of the second wafer, and the two wafers are affixed to one another such that the first and second capacitor plates are arranged in parallel, spaced-apart relation.
Manufacturing a low profile current measurement connector
A current measurement connector may include a first part and a second part. Each part may include a mount and a joint. The first and second part may be joined via the respective joints through a current transformer interposed between the first and second parts. The respective mounts may be configured to receive a current from a current source and pass the received current through the current transformer via the first and second parts inducing a current in the current transformer. The induced current may be useable to measure the current from the current source.
