What is glass frit used for?
Glass frit bonding is used to encapsulate surface micro-machined sensors, i.e. gyroscopes and accelerometers. Other applications are the sealing of absolute pressure sensor cavities, the mounting of optical windows and the capping of thermally active devices.
What is frit seal?
Laser glass frit sealing is a joining method predestined in electronics for the sealing of engineered materials housings in dimensions of some 1 mm2 to several 10 mm2. The application field ranges from encapsulation of display panels to sensor housings.

What kind of bonding is used in glass frit?
Glass frit bonding technology is a wafer bonding method using an intermediate glass layer. This bonding technology is processed at temperatures below 450 °C. Almost all the materials used in MEMS can be bonded using glass frit (55).
What do you need to know about frit bonding?
In glass frit bonding technique, the material must be soft enough to wet the surface for bonding the wafers and seal the MEMS structures, but not too soft to flow into them (57).
Why do glass frit structures need to be heated?
A bond surface activation is not necessary to promote a higher bonding strength. The printed glass frit structures are heated to form compact glass. The heating process is necessary to drive out the solvents and binder. This results in a subsequent particle fusion of the glass powder.
How is screen printing used for glass frit bonding?
Screen printing, as a commonly used deposition method, provides a technique of structuring for the glass frit material. This method has the advantage of material deposition on structured cap wafers without any additional processes, i.e. photolithography. Screen printing enables the possibility of selective bonding.
