In a vacuum environment, the pivotal conduit for secure energy transmission.  Vacuum electrical power feedthrough is a key through component specially designed for vacuum systems. Its core function is to safely and reliably transfer electrical energy from the atmospheric environment to the vacuum interior while absolutely maintaining the vacuum seal of the cavity. It is the indispensable “energy link” that connects the external power source with the internal load of the cavity.   This component has solved the core problem of stable power supply under high vacuum conditions, and is the foundation for the reliable operation of various heating, high-voltage, and particle beam processes.     Design core: Sealing, insulation and current carrying capacity   The design of vacuum electrical power feedthrough is centered around three core aspects: sealing, insulation, and current-carrying capacity.   (1) Based on the mature ceramic-metal brazing technology, an atomi...

Hexagonal boron nitride is an excellent self-lubricating ceramic capable of withstanding extremely high temperatures while maintaining its lubricating properties, even in high-vacuum environments. Boron nitride (BN) crucibles are typically manufactured from hot-pressed boron nitride blanks, ensuring high density and structural integrity. Mechanically, hexagonal boron nitride behaves similarly to graphite, but it offers the additional advantage of outstanding electrical insulation.   Compared with graphite crucibles, BN crucibles exhibit significantly lower risk of carbon contamination and demonstrate greater chemical inertness in many high-temperature processes. In comparison with alumina crucibles, BN crucibles show lower wettability to molten metals, making them especially suitable for applications that demand high purity and minimal interaction between the melt and the container. While different crucible materials are optimized for different process conditions, the appropriate s...

  High purity Sapphire viewports   offer a hermetically-sealed lens with upgraded optical, mechanical, and corrosion properties across a wide spectrum. Innovacera’ Sapphire viewports are rated for both high vacuum(HV) and ultrahigh vacuum(UHV) applications. The use of high purity sapphire and low expansion alloys allow these viewports to be repeatedly baked out at temperatures up to 350°C. The crystal orientation of our sapphire viewports is normal to the optical axis, also referred to as a 90° orientation. All viewports up to one-inch in diameter are made with UV grade sapphire.

Vacuum chucks are used in the thinning, dicing, cleaning, handling, and other processes of semiconductor electronic chips, like wafers. Why choose microporous ceramic vacuum chucks? 1. During the polishing and cleaning process of wafers, polishing liquid and water mist enter the working table, causing corrosion. And the microporous ceramic vacuum chucks resist corrosion. 2. The microporous ceramic vacuum chuck has no environmental pollution such as light, heat, and electromagnetic, unlike the rubber or other materials vacuum chuck. And the rubber or other materials vacuum chuck will be in direct contact with the surface of the item, so it is very easy to wear. Therefore, the porous ceramic has high temperature resistance and chemical corrosion resistance, light structure, and electrical insulation. So it is the best choice for vacuum chuck. 3. With its special porous structure, the microporous ceramic has very small holes and can be machined to very precise flatness. Combined with...
