In high vacuum and ultra-high vacuum systems, the electrical connections or functional components crossing the vacuum boundary are always the key factors affecting the stability and lifespan of the system. Traditional organic seals or mechanical compression structures often encounter risks of aging, gas release and sealing failure under high temperature, thermal cycling and long-term operation conditions.  In response to this industry challenge, we have introduced the  Ceramic Vacuum Feedthrough , manufactured using a mature high-temperature vacuum brazing process. Through the mature high-temperature vacuum brazing process, it achieves a permanent airtight connection between ceramics and metals, specifically designed for the demanding vacuum pressure environment.   Structural Design Based on Engineering Requirements This component uses high-purity alumina ceramic as the insulating core, combined with metal materials (such as stainless steel, molybdenum or Kovar alloy) who...

As the developing of the power electronics, manufacturers are looking for substrate solutions that not only deliver reliable performance but also make sense from a cost and production method. Alumina (Al₂O₃) substrates used in Direct Plated Copper (DPC) technology remain a practical and widely adopted choice across many industries.   A Reliable and Cost-Effective Material Choice   Alumina substrates have been used in electronic package for a long time due to reliable electrical insulation, strong mechanical support, and steady thermal performance, which making them a good choice for a wide range of power and electronic applications used every day.   Alumina has a great advantage for cost-effectiveness when compared with other ceramic materials. Manufacturers can reach to dependable performance without driving up overall system costs, with a well-established supply chain, stable quality, and the ability to support mass production. As a result, alumina DPC substrates are pa...

Electron gun and ion source assemblies work in harsh conditions—high voltage, high temperatures, and ultra-high vacuum alike. This is especially true for ion repeller insulators, a key interface component where reliable electrical isolation and airtight vacuum sealing are both must-haves.   Our glazed alumina ceramic tubes with precision internal threading—engineered as Ion Repeller Ceramic Tubes—are made specifically for these tough applications. As the core insulating part of repeller insulator assemblies, they pair perfectly with alumina bolts, delivering steady performance while ensuring firm mechanical fastening and reliable electrical isolation.     High-Vacuum Design: A Core Engineering Challenge Keeping long-term vacuum integrity in high-voltage setups is a classic engineering hurdle. Insulators have to do three jobs at once: act as mechanical support, block electrical current, and seal the vacuum—all while staying stable when hit with thermal and electrical stres...
