Product Description

imageNon-Standard Vacuum Ceramic Feedthrough Insert

QHXN ceramic-to-metal feedthroughs are custom assemblies for the passthrough of substances or energy from outside a hermetically-sealed chamber to the inside. They provide hermeticity and electrical isolation and remain leak-free in high and ultra-high vacuum.
 

QHXN ceramic feedthroughs are ideal for all applications that require both hermeticity (vacuum-tightness) and electrical insulation. Ceramic-to-metal feedthroughs not only offer absolute freedom from leaks in vacuum and ultra-vacuum environments, but are also resistant to high temperatures, cryogenic temperatures, high pressure and aggressive chemicals. This makes them ideal for use under such conditions.
Ceramic-to-metal feedthroughs from QHXN are defined by the requirements for installation, insulation, and conductor material. The method of interconnection is flexible and often subject to specific customer requirements. QHXN feedthroughs can be divided into the following types:
 
-Feedthroughs for low voltages (up to 12 kV)
-Water-cooled feedthroughs and RF feedthroughs
-High-voltage feedthroughs (20 to 100 kV)
 
-Semiconductor processing equipment
-Particle accelerators
-Furnaces
-Analysis equipment
-Coating applications in vacuum environments
-Satellite instrumentation
-X-ray equipment 
Typical Construction of QHXN Vacuum Ceramic Feedthrough Insert

(1) Conductor,
(2) Washer,
(3) Cap,
(4) Insulator,
(5) Sleeve,
(6) Weld Adapter
 
QHXN ceramic-to-metal feedthroughs use only inorganic materials. The insulators are made from high-purity, high-strength, low-loss alumina ceramics. Metals include stainless steel, nickel, copper, nickel-iron alloys, cupro-nickel alloys, molybdenum. In designs, standard design practices consider electrical characteristics such as flashover, corona breakdown, creep, dielectric strength and puncture resistance.
Braze materials used are silver, copper, silver-copper or gold-copper alloys. Metalization processes include both refractory-metal and active-metal metalizations, depending on the size, geometry and performance requirements for the feedthrough. QHXN uses advanced techniques and methods to control and monitor critical processes, including 100 percent helium leak testing and x-ray measurements for metalization control.
Standard installation mountings for QHXN ceramic-to-metal feedthroughs include:
-Brazing
-Welding (pulse-TIG, TIG, laser, E-beam welding)
-ISO KF flange
-ConFlat flange
-NPT fitting
-1" baseplate
 
1) ceramic tube 97% to 99% high purity alumina and two ends metalizion thin layer of a molybdenum
2) two end SS307L metal caps
3) OHFC copper rod dia 2 mm
 
Final feed through will be achieved- Test for final dielectic strength :2.5K V.
Insulation resistance test will be achieved (1000 V DC,1 Gigaohm)
leak test - Vacuum leak acceptance range better than  1X10 -9 mbar-lit/sec of helium MSLD
Required property of ceramic tubes: The ceramic tube shall conform to the electrical,mechanical,thermal and general property requirements specified as follows.
