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...

The Molybdenum/Manganese metallization developed the technology on   Ceramic-to-metal brazed   assembly, which provides high mechanical strength and good electrical insulation. At the very beginning, it was used in vacuum electronic devices, gradually applied to semiconductors, integrated circuits, electric light sources, high-energy physics, aerospace, chemical industry, metallurgy, instrumentation, machinery manufacturing, and other industrial fields.   So how to choose a material becomes more and more critical for good vacuum brazing. Here we’re mainly discussing about 3 different types of materials that will be used for ceramic-to-metal. Ceramic Al2O3 BeO BN AlN Metala Kovar alloy OFC Stainless steel Mild steel Solder Ag Ag-Cu Cu AU-Cu Au-Ni   The Ceramic materials are required to be high-temperature stabilized and good thermal expansion coefficient. INNOVACERA applies mostly the Al2O3. Since ceramics will not be directly wetted, whi...

  How to prevent moisture or gas penetration while enabling electrical or optical signal transmission; and how to protect sensitive optoelectronic components from environmental influences. These are common challenges faced during the design process.   This is when the “hermetic packaging” technology, which has been in mature use for decades, comes into play. It can achieve signal and power transmission while maintaining air-tightness. Hermetic packaging is also used for optical signal transmission. For example, vacuum – sealed optical lenses or flat – window tube caps are often used in the packaging of sensors.     The two transmission functions of hermetic packaging are electrical signal transmission and optical signal transmission.   – Electrical Power/Signal Transmission: Hermetically sealed connectors can conduct through the sealed housing while preventing the intrusion or escape of moisture, gas and other substance. – Optical Signal Transmission: Hermetical...
