A modern Nd:YVO4 crystal diode-pumped solid-state laser generating a 532 nm wavelength radiation with a nanosecond pulse time was used for the research. Influence of laser parameters such as beam power and pulse repetition frequency on a heat affected zone and carbonization was investigated. Quality and morphology of laser-cut substrates were analyzed by optical microscopy. High quality laser cutting of printed circuit board substrates was obtained without delamination and surface damage, with a minimal carbonization and heat affected zone. The developed process was implemented on the printed circuit assembly line.}, type={Article}, title={Processing of printed circuit boards using a 532 nm green laser}, URL={http://ochroma.man.poznan.pl/Content/118245/PDF-MASTER/OPELRE_28_2020_P_Ciszewski.pdf}, doi={10.24425/opelre.2020.135258}, keywords={laser cutting, flexible printed circuits, heat affected zone (HAZ)}, }
