DRC / Metrigraphics DivisionMetrigraphics LLC is a leading worldwide supplier of ultra-high, precision, custom components for Original Equipment Manufacturers (OEMs). They have applied their core technologies of electroforming, photolithography, and thin-film sputtering to help customers increase the performance, accuracy, and reliability of state-of-the-art instruments and devices. Their process technologies are utilized in fabricating complex 2-D and 3-D micro-components and micro-circuits used in medical, biotechnology, telecommunications, semiconductor, industrial, and consumer markets.

Their primary areas of expertise are listed below.

  • Electroforming
Through a combination of photolithography and their proprietary process technology, they can fabricate complex 2-D and 3-D micro-structures per the specific dimensional design specifications of their OEM customers. Micron size features at sub-micron tolerances can be achieved in Au, Cu, NiCo, or Ni materials.
  • High Density Flexible Circuits
High-resolution photolithography, thin-film coating, and micro-miniature 2-D and 3-D precision electroforming are combined to produce high density, multi-layer flexible circuits with 5-micron traces and spaces. This technology allows medical product designers to install communicating transmitters and transducers directly into intra-vascular, subcutaneous or implantable devices for diagnostic imaging, monitoring or drug administration. High-density circuitry can be used inside devices with diameters of only 1.25mm (e.g. catheters). A wide variety of in vivo and in vitro microcircuits have been produced in high volumes on various substrates, including PZT, alumina, glass, and flexible polyimides.
  • Micro-Nozzles/Orifice Plates
DRC provides electroforming apertures (≥ 1 micron) for nozzle and orifice plates used for precision jetting of liquids and gases. Funnel-shaped and straight-walled apertures are available from this process for a wide variety of microfluidic applications for medical and biological instruments and devices.
  • Micromechanical Parts
High aspect ratio micromechanical parts (gears, cams, springs and coils) are produced by electroforming, ion beam etching, LIGA, and other processes.

  • Precision Measurement and Control

They have applied precision electroforming to produce a wide variety of devices for control, test, and measurement applications in medical and analytical instrumentation (e.g. spectrometers) on glass, quartz and other substrates, both coated and non-coated. In applications where accuracy, repeatability and precision are critical, their engineers have developed processes to produce key instrument components. Some products that they routinely supply are:

  • Slits
  • Grids
  • Targets
  • Reticles
  • Gratings
  • Encoder Scales
  • Encoder Disks
  • Other Optical Components
  • Ion Beam Etching

Precision patterns can be etched in almost any material up to a depth of a few microns using Ion Beam Etching. Depth-to-width ratios can be as much as 5:1 and multi-layer metalizations are feasible. Pattern relief etching of dielectric substrates, such as glass, is possible to precise depths of 10 angstroms!

  • Thin Film Sputter Deposition

Using state-of-the-art sputter deposition equipment, they can deposit a very wide range of metals at Angstrom level thicknesses on a wide range of substrate materials.
