Device makers have a choice of whether to specify an additive or subtractive process for fabricating the micron-scale circuits used in their products. Knowing the basic differences between the two is important.
The additive process defines circuit lines by adding (electroplating) conductive material on top of a thin metal film that’s been fully-sputtered onto a substrate.
Medical design is increasingly impacting miniaturization. Testament to this, as a micron-scale process developer and manufacturer, Metrigraphics is receiving more and more requests from biosensor and device designers looking to push the limits.
Our proprietary photolithography process ensures that you get more consistent trace definition, thinner and therefore more flexible circuits (where needed) and more uniform circuit lines (i.e., same width top and bottom).
We design and fabricate ultra-small, micron-scale optical components that include: Rotary discs and linear encoder scales, Test targets, for testing, and Reticles.
As biosensor circuits continue to get smaller and more complex the need for circuit designers to thoroughly understand both their breakthrough opportunities and manufacturing limitations is critical to medical market success. Metrigraphics has been perfecting advanced circuit manufacturing for decades, and would like to share some tips with you as you explore your next-generation medical or biosensor circuit designs.
Metrigraphics, a leading process development and manufacturing resource for sub-miniature circuits and electroformed structures, will feature its latest micron-scale flexible circuits and thin film devices at IMS, May 24–26 in San Francisco, Calif.
