How Piezo-Based Motion Can Improve The Performance Of Laser Drilling Systems

PI - laser drilling

Advances in laser technology, particularly ultra-short laser capabilities, are making laser drilling the preferred method for creating small holes in various materials. This approach, known for its cold ablation process and minimal post-processing requirements, finds applications in aerospace cooling, fuel injection, inkjet printers, and PCB microvia creation.

Various laser drilling methods exist, such as single-pulse, multi-pulse, trepanning, and helical drilling, each with its advantages and requirements for precise motion control. Piezoelectric motors are favored for their nanometer-level accuracy and intricate motion profiles. High-performance controllers, often employing standard network protocols like EtherCAT®, are crucial for error correction and closed-loop operation.

This white paper aims to explore different laser drilling system implementations and their pros and cons.
