SCHOTT Electronic Packaging is the only company in Europe that supplies all types of hermetic housing technologies. For more than 10 years, SCHOTT has accumulated a strong foundation in the manufacture of high temperature cofired ceramics (HTCC). Now, SCHOTT is also able to supply low temperature cofired ceramic (LTCC) housings through its partnership with VIA electronic.
Multilayer ceramic packages are ideal for more complex packaging solutions, such as micro-electronic-mechanical systems (MEMS) and high frequency applications because such packages are hermetic and enable a large number of electrical feedthroughs within very small spaces.
With the combination of a broad technical competence and worldwide service network, customers can enjoy excellent support from the initial stages of layout development through to manufacturing and final delivery of the ceramic packages. Furthermore, SCHOTT offers:
High and low temperature cofired multilayer ceramics (HTCC and LTCC) are particularly suited for applications with special signal wiring and feedthrough density requirements, such as:
Multilayer ceramic packages are produced from a combination of metal pastes and ceramic green sheets. These green sheets contain a small proportion of organic substrates to achieve flexibility and the possibility to perform punching and green cutting processes.
SCHOTT has proprietary recipes for green sheets and refractory metal pastes used in the manufacture of HTCC. For LTCC, the DuPont 951 green sheet is widely used in combination with various metal paste systems, depending on the metal surface application (soldering, wire bonding, etc.) Typical processes involve via punching, via filling, screen printing of pattern, laminating and firing.
In the final manufacturing step, the two-dimensional green sheets are layered on top of each other to form a three-dimensional multilayer ceramic package.
Two types of multilayer ceramics are available; a full ceramic package (e.g. by providing a cavity for the devices) or an essential component for a more complex hybrid package including additional optical, thermal or mechanical functionalities.
Features / Specifications
Microelectronic packages are customized products manufactured according to customer specifications. A typical package is composed of the metal body, ceramic substrates, optical components (e.g. window, lenses, etc.) and heat sink materials. As such, the design and specifications of different microelectronic packages can vary greatly depending on the application in which they are used in and may, amongst others, include the following features:
Forms of Supply and Product Packaging
All products can be packed individually and supplied on trays.
