Quality Assurance

SCHOTT Electronic Packaging endeavors to provide reliable, high quality products.

Glass-to-Metal and Ceramic-to-Metal Seals

Hermetically sealed products from SCHOTT Electronic Packaging undergo vigorous testing and quality assurance programs to ensure the high quality our customers expect from SCHOTT products. These processes include test procedures according to MIL STD 883, MIL PRF 38534 JEDEC 9 and Telcordia, such as:

Hermeticity
Electrical insulation
Lead fatigue
Visual and dimensional examination
Solderability
Thermal shock

Large-scale Feedthroughs

During production and at final inspection, each large-scale feedthrough is examined carefully to ascertain pressure stability and hermeticity as well as electrical performance.

Examples of standard quality assurance checks include:

Helium leak check (mass spectrometer)
Pressure test
Electrical tests (high pot and insulation resistance)
Visual and dimensional inspection

To qualify new designs, the designs are subject to intensive testing programs which may - depending on the application – additionally include:

Cryogenic shock
Temperature cyclin
Voltage surge
Thermal and radiological aging
LOCA test
Heating under electrical load

Glass Powder

Glass powder from the SCHOTT Group is specially tailored to customer requirements. Depending on the end application, the following quality assurance tests can be conducted:

Chemical purity
Grain size
Tg acc. DIN-ISO 7884
α_(20-300)
Softening point
Color

Thermal Cutoffs

Thermal cutoff products undergo vigorous testing and quality assurance processes to ensure stable and reliable quality. In the quality assurance process, we evaluate the operating temperature with tests such as:

High temperature test
High humidity test
Temperature cycle test

Precision Glass Tubes

Precision glass tubes for the encapsulation of electronic components must meet stringent requirements as they are used in special applications such as switches, lamps, identification systems, etc…

Depending on the end use, the following tests can be conducted to assure quality:

Dimensional inspection
Cleanliness of dust and particles
Purity of the glass used
Biocompatibility (for animal ID-systems)

Precision Discs

SCHOTT manufactures precision discs of brittle materials such as glass, ceramic, sapphire, etc… for electronic and special applications.

All products must pass a final inspection test for:
