COMPOSITION OF CONDUCTOR PASTE AND METHOD OF PREPARING CONDUCTOR THICK FILMS USING IT

摘要

A low temperature cofired paste composition containing nanosilver particles and a manufacturing method of the conductive thick film using the same are provided to manufacture the low temperature cofired paste using silver particles of nano size, to reduce the waste of material and to solve the disadvantage that the precision of the electrode morphology is decreased. A low temperature cofired paste composition containing nanosilver particles comprises silver powder of nano-size, glass powder, and vehicle as a solvent in a mass rate of 80:1:19. A manufacturing method of the conductive thick film using the low temperature cofired paste composition comprises a step for screen-printing the paste composition on an alumina substrate with the screen mask; a step for drying the paste composition at 120deg.C for 20 minutes to remove the vehicle so as to form a thick film; and a step for heat-treating the thick film at 250~450deg.C for 15 minutes.
