Abstract: Fluxes and solder pastes can be classed as structured fluids, which are able to support shear stresses and even exhibit yield stresses. The flux properties and interactions between flux and solder particles affect how solder pastes flow when subjected to shear stresses during printing. Solder paste printing performance should therefore depend on the rheology of the flux and paste and in order to understand and improve solder paste printing, the rheological properties of solder paste need to be characterized. However, there is little literature published on solder paste rheology and no clear correlation between solder paste rheology and printing performance.
