Abstract
For gluing stress-sensitive component substrates (BS) having a system carrier (ST), it is proposed to provide spacing structures (AS) between the two surfaces to be glued, the structures assuring a defined arrangement of the two surfaces to be glued. The spacing structures can be created through a screening process, and the space between the spacing structures can be filled with glue (K).
Claims15
A component in which a crystalline substrate (BS) having SAW component structures is connected by a glue (K) to a system carrier (ST),
- in which the system carrier forms the lower part of a ceramic housing and has an uneven surface;
- in which spacing structures (AS) are disposed between the substrate and the system carrier in a regular and defined pattern such that they create contact points or surfaces, all located in one plane, for the substrate;
- in which flat surfaces of the substrate and the system carrier are oriented at a defined angle, or virtually parallel, relative to one another;
- and
- in which the space between the spacing structures (AS), the substrate (BS) and the system carrier (ST) is partially or completely filled with glue (K).
A method for limiting the error scattering in the gluing of stress-sensitive SAW components (BS) having a system carrier (ST), which has a flat but uneven surface and forms the lower part of a ceramic component housing (ST, GW),
- in which spacing structures (AS) are created on or mounted to the surface of the system carrier prior to gluing such that the structures form contact points or surfaces, all lying in one plane, for the component (BS);
- in which glue (K) is applied to one of the surfaces;
- in which the component (BS) is positioned on the contact points or surfaces;
- and
- in which the glue is cured at a high temperature.
