Space and satellite hardware uses hermetic feedthroughs to pass electrical power, signals, RF, and fiber optic lines through pressure boundaries – between pressurized electronics enclosures and vacuum, or through thermal-vacuum test chamber walls. Space-grade feedthroughs must survive launch vibration, radiation exposure, thermal cycling from cryogenic to high temperatures, and indefinite
Synchrotrons and particle accelerators require UHV conditions throughout their beam paths so that charged particles or photon beams travel with minimal gas scattering, charge buildup, and beam-gas interaction. CF flanges with copper gaskets, hermetic instrumentation feedthroughs, UHV viewports, and ceramic vacuum chambers are the primary vacuum components used in these
Transmission electron microscopes (TEMs) and high-performance scanning electron microscopes (SEMs) use UHV or near-UHV conditions to protect the electron source, column optics, and sample environment. Hermetic electrical feedthroughs carry high-voltage bias, heater power, and signal lines into the column without leak paths. In situ TEM holders incorporate miniature hermetic feedthroughs
Defense and military electronics rely on ceramic-to-metal hermetic seals to protect sensitive electronic components from moisture, pressure, vibration, and thermal extremes over service lives that can exceed 20 years. Ceramic-to-metal brazed feedthroughs and hermetically sealed packages are used in radar systems, missile guidance electronics, undersea sonar equipment, aircraft avionics, and
Ceramic-to-metal seals are manufactured through a multi-step process: the ceramic is formed, fired, and then metalized on the bonding surfaces using the molybdenum-manganese (Mo-Mn) process or active metal brazing (AMB). The metalized ceramic is then brazed to the metal component in a controlled-atmosphere furnace using a filler metal – most
Each year, the annual conference hosted by the American Society for Mass Spectrometry (ASMS) brings together thousands of scientists, engineers, and technology companies working at the forefront of analytical instrumentation. MPF Products is excited to be returning this year to exhibit at the 74th ASMS Conference on Mass Spectrometry and
Blue Ridge Optics, a division of MPF Products, Inc., is excited to announce a significant expansion of their coating capabilities with the addition of state-of-the-art Ion Beam Sputtered (IBS) coatings. This advancement complements their established expertise in electron-beam evaporation. Now, Blue Ridge Optics offers an even broader range of solutions
When Hurricane Helene hit, it brought significant challenges to our region. MPF faced a massive obstacle as power and regional internet service was knocked out with no idea of when it would be coming back. Just north of MPF in NC, the area was completed devasted. But in true MPF
Copper conductors, commonly used in various industries, can sometimes get bent during shipping due to sudden impacts or rough handling. Since the copper is annealed and very soft after brazing, it’s particularly susceptible to bending even with protective fixtures around the weld adapter. While this may look concerning, it’s easy
