Flexible Microcircuits

Photonics MarketplaceFlex Circuits That are Multiple Layers High, with Traces to 3 Microns

Using additive photolithographic processes, extreme-resolution, microflex (ERMF) circuits can be manufactured with traces and spaces as small as five microns. They can also be delivered in complex, high-resolution shapes and patterns. They 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 circuits that achieve product-design goals not possible any other way.

Products include:
  • Single-layer flex
  • Multi-layer flex
  • Coils
  • Sensor components
  • Electrodes (neuro-stimulation)

Applications for single-layer circuits include invasive medical devices and in-vitro diagnostics. Multi-layer 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.
