PCB Micromachining
PCB micromachining enables extremely precise, contact-free processing of printed circuit boards with micron-level accuracy. Laser technology creates fine features, micro-holes, isolation paths and complex geometries without mechanical stress, ensuring exceptional quality for advanced electronics manufacturing.
The Future of PCB Manufacturing Starts Here
Micron-Level Precision
The laser operates with micron-level accuracy, enabling the production of ultra-fine traces, micro-holes, and complex geometries with outstanding precision and repeatability.
Contact-Free Processing
Because the process is completely non-contact, it eliminates mechanical forces, vibration, and material deformation, allowing even thin and delicate PCBs to be machined without damage.
No Tool Wear
Since the laser beam is a non-contact tool, there is no tool wear. This ensures consistently high machining quality while eliminating tooling replacement costs and production downtime.
Burr-Free Results
Optimized laser parameters produce clean, burr-free edges with minimal post-processing, resulting in higher product quality and improved manufacturing efficiency.
Exceptional Repeatability
Every component is manufactured with the same high level of precision, making laser micromachining ideal for mass production and high-reliability electronic applications.
Complex Micro Features
Laser technology enables the creation of micro-holes, isolation channels, fine contours, intricate cut-outs, and high-density circuit structures that are difficult or impossible to achieve using conventional mechanical machining.
High-Speed Production
High-speed galvanometer scanning significantly reduces processing times while maintaining micron-level precision throughout the manufacturing process.
Minimal Heat-Affected Zone
The laser concentrates its energy into an extremely small area, minimizing heat input and protecting the surrounding material as well as delicate PCB structures from thermal damage.
Consumable-Free Technology
No milling cutters, drill bits, or other consumable tools are required, resulting in lower operating costs, reduced maintenance, and increased production efficiency.
Laser PCB Milling vs. Conventional PCB Milling
Digital precision without mechanical tool wear.
Laser PCB milling combines ±0.01 mm positioning precision, scanning speeds of up to 14,000 mm/s and up to 100,000 hours of laser source lifetime with digitally programmable processing. Unlike conventional mechanical PCB milling, the laser process does not rely on a rotating cutting tool, enabling flexible geometry changes and highly automated production.
