High-Precision PCB Topologies Formation by Selective Laser Micromachining

Abstract:

The paper considers possibility of using laser radiation to form and correct printed circuit topology boards through micromachining. Processes arising from the interaction of ultrashort laser pulses with processed thin-film coatings are considered. The dependence of the effect of a variable sequence of laser pulses on the quality of the formed holes in coating is presented. Experimental data on the selection of optimal exposure modes of femtosecond radiation on a multilayer coating for selective ablation are presented. Femtosecond laser micromachining allows the precision formation of topological contours, regardless of treated coating type, its thermal and electric conductive properties.
