Our TechNotes are intended to inform and guide the unsure through terms as well as designs for laser friendly scope of work. Our Microvia/PCB notes have suggestions for limits on via size versus dielectric thickness (aspect ratio). It also describes fiducial/target types that work well. Next, our Duroid notes describe methods for laser routing various circuits depending on the copper patterns. Finally, our Ceramic notes detail expectations for visual quality as well as tolerances on finished parts. Finally, some design guidelines help minimize problems from feature spacing versus thickness.
