主 题：laser sintering copper nanoparticles printed electronics
摘 要：This study explores the feasibility of different laser systems to sinter screen-printed lines from nonconductive copper nanoparticles(Cu NPs)on polyethylene terephthalate polymer *** materials are commonly used in manufacturing functional printed electronics for large-area ***,optical and thermal characterization of the materials is conducted to identify suitable laser sources and process *** diode(808 nm),Nd:YAG(1064 nm and second harmonic of 532 nm),and ytterbium fiber(1070 nm)lasers are *** parameters for sintering the Cu NPs are identified for each laser system,which targets low resistivity and high processing ***,the quality of the sintered tracks is quantified,and the laser sintering mechanisms observed under different wavelengths are *** considerations are discussed to improve the laser sintering process of Cu NPs.
