Since the 1980s, Low Temperature Co-fired Ceramics (LTCC) have moved from space applications to mobile phones. The Swedish Ceramic Institute now wants to see large-scale LTCC production in Sweden.
According to Jesper Brandt, researcher at the Ceramic Institute in Gothenburg, LTCC is gaining ground in Sweden. Together with eight Swedish companies, the institute has set up a development project to teach Swedish designers to make chips in LTCC. If everything goes according to plan, production of complete chips will start in Sweden as well. The first prototypes have already been manufactured at the Ceramic Institute. Jesper Brandt says:

"As far as I know, we are alone in producing LTCC chips in Sweden at present."

The institute itself will not introduce volume production, and so far it only produces a certain type of chip, including only wires and no embedded components. However, the aim is to develop chips equipped with both resistors, capacitors and embedded radio filters for high frequencies.

Although LTCC is well established in Europe, Asia and the US, the institute wants to promote Swedish LTCC production. One of the companies involved in the institute's project, contract manufacturer Maxitech Elektronik, which today makes components using thick film technology, is also seriously considering starting production of LTCC chips. Ericsson Microelectronics has already opted to use LTCC for its Bluetooth radio module, which is expected to become a high-volume product.
