    The Preload Matters…A Lot

    MD Staff
    The right preload on a threaded fastener can mean the difference between success and failure.
    Hermetic wire feedthroughs can use point-to-point wire harnessing to reduce the number of connection points which are associated with voltage drops and degraded signals. The critical design considerations for feedthroughs are good seals, strength to withstand expected mechanical stresses and minimal electrical losses. Typical uses include high-voltage electrical switches, semiconductor wafer-processing equipment, medical imagers, military ordinance controls and space simulation vacuum chambers.

    The Case for Wire Feedthroughs

    Ed Douglas
    Bulkhead connectors may be more popular for passing wires and cables through walls, but for many applications, feedthrough connectors can handle the task more elegantly and more...

    Weld Them or Braze Them? How Should You Join Metal Parts?

    Steve Marek
    Both joining methods have their place, but it seems few engineers know brazing is an economical method for making strong, permanent metal joints.
