LAPP Insulators Alumina:
Integrated Engineering Development
(hall B1/ stand area 219/320; 325/426; 217/318)
LAPP Insulators Alumina manufactures for more than 45 years semiconductor housings for high performance electronics.
The company is quality leader in the high power >1 GW domain. Each year around 300 000 housings are produced. The core technology is hard brazed aluminium oxide (Al2O3) to metals such as copper (OF, SE) or Ni-Fe-alloys as well as stainless steel. As the leading technology company in the field of ceramic-to-metal sealing, LAPP Insulators Alumina offers products for vacuum, medicine, laser, measurement, plasma, x-ray, accelerator, radiofrequency, chemical micro reactors, sensors and energy management. The roots of LAPP Insulators Alumina go back to the ceramics division of the world famous Siemens Corporation. Employees of the Alumina are producing (in addition to thyristor and diode housings), metallized ceramic vacuum interruptor tubes, vacuum feedthroughs and isolators and customized special products. Standard programs have been created for the vacuum feedthroughs and isolators to meet the requirements for vacuum designs like ISO and CF. Special know-how in the ceramic-to-metal arena enables a wide range of industrial electronic applications to be served: from bondable substrates for thin or thick wires through laser beam generator tubes to Kicker-Tubes for accelerator applications. Designing such demanding components is done by LAPP Insulators Alumina with Finite Element Analysis (FEA) calculations to determine the thermo-mechanical loads. The best versions can be optimized from the outset – eliminating guesswork and trial-and-error, before the first part is manufactured. This is a big customer benefit by saving development time and costs. Ceramic-to-metal assemblies made by LAPP are displaying a combination of typically ceramic properties like electrical isolation and typically metallic attributes such as weld ability, which can be exactly located at the position required by the application. The customers get a multi-functional benefit, utilizing the best properties of ceramics and metals in a single component. Thereby the brazed compound is vacuum dense. Alumina offers the complete mastery of process technologies, from the passive and active brazing to glas bonding for ceramic-ceramic-joints. The newest product families made by LAPP Insulators Alumina are 3d-printed Alumina components for micro reaction applications.
