  2. Birmingham gauge - Wikipedia

    en.wikipedia.org/wiki/Birmingham_gauge

    Smaller gauge numbers indicate larger outer diameters. [4] Inner diameter depends on both gauge and wall thickness. The following chart shows nominal inner diameter and wall thickness for regular-wall needles. [4] [5] Thin-wall needles (not shown) have identical outer diameters but larger inner diameters for a given gauge.

  3. Flying probe - Wikipedia

    en.wikipedia.org/wiki/Flying_probe

    One limitation in flying probe test methods is the speed at which measurements can be taken; the probes must be moved to each new test site on the board, and then a measurement must be completed. Bed-of-nails testers touch each test point simultaneously and electronic switching of instruments between test pins is more rapid than movement of probes.

  4. French catheter scale - Wikipedia

    en.wikipedia.org/wiki/French_catheter_scale

    An increasing French size corresponds to a larger external diameter. This is contrary to Birmingham gauge, where an increasing gauge corresponds to a smaller diameter needle. The French size is a measure of the outer diameter of a catheter (not internal drainage channel, or inner diameter). So, for example, if a two-way catheter of 20 Fr is ...

  5. Injector pen - Wikipedia

    en.wikipedia.org/wiki/Injector_pen

    Today, pen needles are manufactured at shorter needle lengths than required for typical vial and syringe administration, which decreases the pain associated with injection. [2] They are available in multiple lengths and gauge of needle , including 3.5mm, 4mm, 5mm, and 8mm lengths, and 31 through 34 gauge. [ 8 ]

  6. Hook gauge - Wikipedia

    en.wikipedia.org/wiki/Hook_Gauge

    A hook gauge. A hook gauge or needle gauge is a measuring device used by crocheters and knitters to test the sizes of particular crochet hooks and knitting needles. Hook gauges are usually made of plastic or aluminum and have sizing holes from 2mm to 11mm diameter. A hook gauge also functions as a ruler to test the size of a test swatch of ...

  7. Hypodermic needle - Wikipedia

    en.wikipedia.org/wiki/Hypodermic_needle

    Various needle lengths are available for any given gauge. Needles in common medical use range from 7 gauge (the largest) to 34 (the smallest). 21-gauge needles are most commonly used for drawing blood for testing purposes, and 16- or 17-gauge needles are most commonly used for blood donation, as the larger luminal cross-sectional area results ...

  9. Probe card - Wikipedia

    en.wikipedia.org/wiki/Probe_card

    Advanced Tester Resource Enhancement (ATRE) [5] is a powerful means of increasing the number of DUTs that can be tested by a probe card in parallel (or in one touchdown during which probe card needles remain in contact with the wafer DUTs). ATRE allows the sharing of tester resources among DUTs using active components, which have the ability to ...
