Screen printing particle size distribution

The flow properties of an adhesive are largely controlled by its inherent viscosity and by the alteration of its viscosity through the addition of diluents and fillers. How properties are important for screen-printing, automatic dispensing, and capillary flow, and can be tailored by the type of filler, amount of filler, and the particle-size distribution. 

There are three critical parameters of the paste that relate to screen printing (1) the ratio of the solids content, (2) the particle size distribution, and (3) the viscosity.
