A method of conductively bonding a test probe tip having an electrically conductive element to a device under test (DUT) having an electrical connection point, the method comprising: positioning the electrically conductive element of the test probe tip proximate to the electrical connection point of the DUT; dispensing a UV-cure conductive adhesive between the electrically conductive element and the electrical connection point of the DUT, the dispensed UV-cure conductive adhesive continuously covering at least a portion of the electrically conductive element and at least a portion of the electrical connection point of the DUT; and bonding the dispensed UV-cure conductive adhesive to the electrically conductive element and the electrical connection point of the DUT by applying UV-light from a UV-light source to the dispensed UV-cure conductive adhesive.

Because reprocessing or refurbishing of physiological sensors reuses large portions of an existing sensor, the material costs for refurbishing sensors is significantly lower than the material costs for making an entirely new sensor. Typically, existing reprocessors replace only the adhesive portion of an adhesive physiological sensor and reuse the sensing components. However, re-using the sensing components can reduce the reliability of the refurbished sensor and/or reduce the number of sensors eligible for refurbishing due to out-of-specification sensor components. It is therefore desirable to provide a process for refurbishing physiological sensors that replaces the sensing components of the sensor. While sensing components are replaced, generally, sensor cable and/or patient monitor attachments are retained, resulting in cost savings over producing new sensors.

A repairable rigid test probe system includes an annular gimbal supported by an annular gimbal bearing of a probe card assembly, a test substrate seated and aligned within the annular gimbal, a rigid die including thick periphery and a thin center containing an array of through holes that is aligned above the test substrate, and an array of rigid probes inserted into each of the array of through holes, where each rigid probe includes: a tail end that contacts a connection on a facing surface of the test substrate, a collar limiting a distance of insertion, and a tip that contacts a corresponding contact on a facing surface of a device under test.

A probe for direct nano- and micro-scale electrical characterization of materials and semi conductor wafers. The probe (10) comprises a probe body (12), a first cantilever (20a) extending from the probe body. The first cantilever defining a first loop with respect to said probe body. The probe further comprises a first contact probe being supported by said first cantilever, and a second contact probe being electrically insulated from the first contact probe. The second contact probe being supported by the first cantilever or by a second cantilever (20b) extending from the probe body.

A test probe assembly includes: a conductive pipe; a probe inserted in the pipe without contacts and elastically retractable along a lengthwise direction; and an insulation probe supporting member configured to support the probe between an inner wall of the pipe and an outer surface of the probe. The test probe assembly of the present disclosure is improved in noise shield performance and convenient in repairing the probe since the probe is mounted to a probe socket as supported in a metal pipe without contacts.

An interface structure connecting an electronic component to a circuit board. The interface structure includes a base defining an elongated through hole with a central axis and a coil spring retained in the elongated through hole. The coil spring has a proximal portion and a distal portion extending from the elongated through hole in an uncompressed condition and being offset at an angle with respect to the central axis. As the coil spring is compressed, the coil spring creates a force having a component substantially perpendicular to the central axis.
