Tekna Seal Oxide Free Glass to Metal Hermetic Seals:
|
|
|
The Tekna Seal proprietary oxide-free glass to metal hermetic
seal process eliminates the need for pre-oxidizing of the
metal components prior to glass sealing. This lack of heavy
oxide interface between glass and metal allows for:
| • |
Increased pressure withstanding |
| • |
Higher levels of hermeticity |
| • |
Repeatable, reliable processing |
Eliminates the need for post oxide removal:
| • |
Glass and metal are clean, free of etching
residue |
| • |
Hazardous waste stream eliminated |
|
Traditional Glass to Metal Sealing Process:
|
 |
Traditional glass to metal seals rely on a visible oxide
layer formed on the metal components to allow glass flow and
adhesion. This oxide layer limits the strength and hermeticity
of a conventional glass to metal seal. This process also requires
an additional operation to remove the oxide from other surfaces
of the assembly. This cleanup process is usually a chemical
etch, which may diminish dimensional tolerances or contaminate
the materials. |
