High throughput CO2 laser via drilling enhanced by advanced AOD technologies (Conference Presentation)
Author(s): Ruolin Chen; Geoffrey Lott; Christopher Ryder; Nicolas Falletto

Paper Abstract

Here, we demonstrate the benefits of acousto-optic deflector (AOD) technologies for advanced spatio-temporal beam control in CO2 via drilling. Spatially, we demonstrate the ability to drill multiple via sizes on the fly, enabling the drilling of multiple via sizes on one panel within one single pass. Temporally, we demonstrate the ability to slice one laser pulse into multiple sections, enabling fine-tuning of the pulse energy profile delivered to the workpiece. Furthermore, we compare via drilling results using AODs to those drilled with traditional punch processes, showing advantages in both throughput and quality in comparison to traditional imaging-based CO2 drilling systems.
