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.
