InnoLas lasers cut printed circuit boards at high speed

Speeding up free-form cutting processes of printed circuit boards (PCBs) can be an extremely challenging task. While commonly used milling processes introduce vibration to sensitive devices, the use of CO2 lasers causes charring and unwanted conductive residues on the PCB.

Using 355 nm UV lasers prevents charring but the low penetration depth at 355 nm requires high laser pulse energies ending up with low cutting speeds, expensive system pricing and poor laser lifetime. Going to high rep-rate, short pulse 532 nm lasers, the use of InnoLas Photonics’ BLIZZ lasers enables up to 30 mm/sec high speed PCB cutting processes with unparalleled cutting quality, outstanding laser performance and reliability, combined with unrivalled system costs.
