High-Density Microflex 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.
Metriform II is DRC's technique for the
selective application of several photolithographic processes
in combination with thick and thin film techniques to create
custom, high-density passive circuits or compact assemblies.
Who needs Metriform II components?
Design and application engineers and
high-technology manufacturers who need to fabricate new,
proprietary, and unusual microcircuits or special
multi-layer assemblies. If your application includes any of
the following characteristics, Metriform II is your
solution:
- Severe size and space constraints
- Chip on-board micro-miniaturization
- Fine lines or conductors (5 microns)
- Multiple layers
- Small vias
- Special substrates (Kapton, ceramics, glasses)
Metriform II Technology includes:
- Thin film (additive) circuitry
- Combinations of sputtered, electroformed, lift-off
evaporation, dry or wet etching, lamination, and silk
screening.
- Fine lines - DRC specializes
in line widths from .001" (25.4 microns) and down. Line
widths and spaces of .0004" (10 microns) are
demonstrated on the free sample. Circuitry on or over
substrate edges is not unusual.
- Multi-layer construction -
Thin glass, Kapton, and liquid polyamides are common
dielectrics. Many other screened, thin-film, or
sputtered dielectrics are also available.
- Special substrates - We have
worked with glass, quartz, fused silica, alumina,
sapphire, stainless steel, Kapton, FR-4, G-10,
copperclad invar, special optical materials, as well as
machined/polished alloys. A wide variety of sizes and
shapes can be accommodated.
