A value that represents the force created by the flow of plastic past the wires of an integrated circuit; also called the sweep index.
The wire-sweep index is the sum of the velocity of viscosity time at each grid point in the model. The result is averaged by the number of grid points.
A wire-sweep index that is high in regions of the model containing wires indicates a possible location for wire breakage.
Since viscosity depends on temperature, shear rate, and the rate of cure, you can reduce a a wire-sweep index by changes to these variables.
