Highest Precision with Laser Micromachining

The progressive miniaturization in electronics, semiconductor processing and manufacturing of medical instruments is characterised by smaller and smaller structures as well as the demand for highest precision in terms of surface quality, absence of burr, and materials residues. While established fabrication technologies increasingly face their limits, laser micromachining provides optimum preconditions for the required quality and precision since machining is accomplished in a contactless fashion and the extent of the heat-affected zone is very small.

Advantages of Laser Micro Machining

• Easy capability of being automated
• Straightforward process monitoring
• Forceless and contactless machining
• Minor heat-affected zone
• Marginal modifications to the microstructure
• Machining free of burr and bulging
• High flexibility regarding design of tiny structures
• High machining speed
• High precision
• Constant machining quality
• No additional tooling costs by wear

For optimum utilisation of the advantages of laser machining, high-capacity machine concepts, such as those being the basis of 3D-Micromac’s high-definition laser systems, are decisive.

Numerous process surveillance methods, like tracking and tracing of process parameters and online energy monitoring ensure additional process reliability.
