Thin Film Ceramic Circuit

The metal deposition methods used in vacuum processes and the flexibility that can be achieved in terms of thickness and type of metallization in particular really set thin film technology apart from printed circuit board technology.

Thin film ceramic circuit.

Thin film technology uses semiconductor and microsystem technology processes to produce circuit boards on ceramic or organic materials. Over the past 40 years ecrim has developed a large number of high precision and high quality thin film technology and circuit products for supporting national key engineering projects. Substrates made from rubalit alumina ceramics. Film resistor film inductor film conductor and other distributed circuit components.

Thin film hybrid microcircuits may be assembled on ceramic substrates such as alumina or beryllia where interconnect conductor lines and bonding pads have been produced by vapor depositing or sputtering thin films of metals then etching the patterns using standard photolithography processes.
