About Mechanical Micromachining

Posalux high-tech 2.5D micromachining solutions are tailored for mass production and mainly dedicated to the electronics industry.


Mechanical micromachining, commonly known as micromachining, is a specialized manufacturing technology that involves the use of micro tools, such as micro-endmills or drillbits, with geometrically defined cutting edges. This subtractive fabrication process crafts devices or features with dimensions in the micrometer range. It mirrors traditional machining in approach but operates on a distinctly smaller scale, necessitating specialized equipment and techniques to define microscale structures or components. Mechanical micromachining provides:

  • Flexibility
  • Cost-effective solution for small-batches
  • Complex geometry
  • Reduced waste
  • Integration
  • Scalability
  • Direct production
