Micro-via drilling of FR4 and filled substrates
The dual laser combination of UV/CO2 effectively excavates material and drills cleanly through both copper and dielectric (non-reinforced or glass-reinforced) materials. The UV laser precisely ablates dielectric material, while the CO2 laser efficiently cuts copper layers. This synergy ensures superior drilling accuracy and minimal thermal damage. The method's adaptability allows for adjustments in laser parameters, accommodating various material compositions and thicknesses, making it valuable across multiple industries requiring precise material processing.
