Conductive patterns need to be sintered for pattern curing after printing, and the quality of the sintering directly affects the overall performance of the conductive patterns. The conductive pattern was produced on the integrated EHD electromechanical printing and sintering equipment, and the conductive pattern was cured by laser sintering. To ensure the printed sintered conductive pattern had good conductivity, the orthogonal tests were applied to study the influencing factors of the laser sintering to determine the optimal laser sintering parameters. The electrical conductivity of the laser sintered pattern was tested by using a multimeter, the result showed that the resistivity of the laser sintering pattern was 5.2 μΩ·cm, which was closed to bulk silver. The surface topography of the laser sintered conductive pattern was studied with an electron microscope. The results show that the surface morphology of the laser sintering conductive pattern is uniform and the porosity per unit area is only 8%, the low porosity greatly improves the conductive performance of the conductive pattern. The results provide reference for the integrated conductive pattern printing and sintering, and for improving the overall performance of laser sintered microconductive patterns.
