Solder paste a move to lead-free solder. Solder paste is thixotropic, meaning that its viscosity changes over time with applied shear force (e.g., stirring). The "thixotropic index" is a measure of the viscosity of the solder paste at rest, compared to "worked" paste. Depending upon the formulation of the paste, it may be very important to stir the paste before it is used, to ensure that the viscosity is appropriate for proper application. The size and shape of the metal particles in the solder paste determines how well the paste will "print". A solder ball is spherical in shape; this helps in
