Speeding up free-form cutting processes of printed circuit boards 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 355nm UV lasers prevents charring but the low penetration depth at 355nm 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 532nm lasers, the use of InnoLas Photonics’ BLIZZ lasers enables up to 30mm/sec high speed PCB cutting processes with high cutting quality, laser performance and reliability.
