Metrigraphics, a leading process development and manufacturing resource for sub-miniature circuits and electroformed structures, is now featuring its latest micron-scale flexible circuits and thin film devices.
Micron-scale flexible circuits can be achieved with six or more layers high with traces (circuit lines) as narrow as 3 microns (11.81 x 10 - 5 inches). Circuits are flexible and thin enough to wrap around objects with diameters as small as a pencil.
Typical microcircuit applications include mobile antennas and high performance bio sensors and electrodes. Any combination of coils, resistors, inductors, conductors, and bridges can be achieved.
To manufacture flexible circuits with such high-trace resolution, Metrigraphics employs a mix of proprietary and industry-standard processes. These include high-resolution photolithography as well as sputtered thin-film and plated metal deposition. Multilayer flexible circuits are constructed of several independently stacked, aligned and interconnected layers composed of very thin sputtered metal or thicker-plated metal, such as gold or copper, on polyimide substrates. Plated conductive vias connect the different layers as required. Metrigraphics offers via sizes down to a 25-micron diameter.
