Feedthroughs and Viewports for Electron Microscopy

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

How Ceramic-to-Metal Seals Are Manufactured and Brazed

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

Straightening Copper Conductors

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
