Abstract
A flux composition includes a flux agent including KAlF4 and CsAlF4; a thickening agent having a first carbon content; a binder having a second carbon content; and an organic solvent; wherein a total carbon content of the flux composition is less than about 1 wt %, based on a total weight of the flux composition. The flux composition is applied onto a substrate by jetting the flux composition through a nozzle orifice of an applicator and onto the substrate.
