Thick film technology is used to produce electronic devices such as surface mount devices, hybrid integrated circuits and sensors.
Thick film circuits are widely used in the automotive industry, both in sensors, e.g. mixture of fuel/air, pressure sensors, engine and gearbox controls, sensor for releasing airbags, ignitors to airbags; common is that high reliability is required, often extended temperature range also along massive thermocycling of circuits without failure.
The manufacture of such devices are an additive process where deposition of several successive layers of conductor, resistors and dieletrica layers onto an electrically insulating substrate using a screen-printing process. A typical thick film process would consist of the following stages:

Famous quotes containing the words thick, film and/or technology:
“Lawyers are like rhinoceroses: thick skinned, short-sighted, and always ready to charge.”
—David Mellor (b. 1949)
“You should look straight at a film; that’s the only way to see one. Film is not the art of scholars but of illiterates.”
—Werner Herzog (b. 1942)
“The successor to politics will be propaganda. Propaganda, not in the sense of a message or ideology, but as the impact of the whole technology of the times.”
—Marshall McLuhan (1911–1980)
