Manufacturing Advantage:
Handling brittle ceramics at a micro-scale requires exceptional engineering finesse. Our proprietary machining and photolithography processes allow us to create complex, non-rectangular geometries while maintaining razor-sharp circuit definitions. The bio-compatible nature of our high-purity Alumina ensures that these substrates meet the stringent requirements of the medical technology and aerospace sectors, providing a reliable platform for your most sensitive micro-sensing applications.
*Note: Probe length, paddle width, and circuit patterns are 100% customizable. We support low-volume prototyping for R&D. Please upload your 3D STEP or Gerber data for a confidential review.
