Using additive photolithographic processes, extreme-resolution, microflex circuits can be manufactured with traces and spaces as small as five microns. These flex circuits can also be delivered in complex, high-resolution shapes and patterns. Microcircuits are produced with very thin layers of sputtered metal, or thicker-plated metal such as gold or copper, on Polyimide substrates. For some designs we can achieve traces as narrow as three microns.
Using electroforming, photolithography and proprietary technology, Metrigraphics makes a wide variety of ultra-miniature microelectronic flex circuits that achieve product-design goals not possible any other way.
Microcircuit products include:
Applications for single-layer microcircuits include invasive medical devices and in-vitro diagnostics. Multi-layer flex circuits (up to six or more layers) include additional conductive layers that are independently stacked, aligned and interconnected. Plated conductive vias connect the different layers as required. Metrigraphics offers via sizes down to a 25-micron diameter.
