Circuit Pack Parameter Estimation Using Rent's Rule

This paper applies an empirically determined relationship known as Rent's rule to the estimation of circuit pack parameters. In particular, equations are derived for 1) the number of leads passing through a region of a circuit pack based on the position of the region, and 2) the total lead length on a circuit pack. The estimation of these parameters is central to the modeling of circuit size and performance as well as many other important circuit parameters. A technique for determining the Rent parameters for a particular circuit pack is also derived. Finally, experimental validation of these models is described.
