Description

This paper presents a method of maximizing the quality of shielded pairs with skin-foam-skin insulation. The method utilizes sensitivities and manufacturing tolerances to predict tolerances for attenuation and impedance. It is demonstrated that higher impedance cables are less sensitive to all dimensional parameters and can be manufactured with higher manufacturing tolerances at lower costs. Based on required manufacturing yield for cables, the limits for manufacturing process tolerances and minimum requirements for quality of materials are estimated.
