Thick film pastes for the production of electronic circuits and sensors.
Heraeus offers a wide range of pastes for thick film circuits such as gold, silver, palladium, platinum or copper conductive pastes. Dielectrics, over glazes and resistive pastes complete the line of thick film products for hybrid applications.
These recommended pastes (
Hybrid Schematic) meet current environmental demands, such as RoHS; by offering Pb, Cd, and Ni free formulations. Specific formulations for plateable, solderable and wire bondable applications make up the range of commercially available products.
Whenever design space is a premium, climatic conditions are harsh and where reliable circuits are needed – such as in the medical technology sector, the aerospace industry, the automotive industry and in telecommuni-
cations, Heraeus thick film pastes are right choice.
Principal processing steps are:
screen printing on temperature resistant ceramic substrates
leveling and drying
firing between 500°C and 1200°C, typically at 850°C.
