Tolerance Analysis

Tolerances—be they mechanical, electrical, optical or whatever—have a severe impact on both product functionality but also manufacturability.  In particular, tolerance stack ups—where one component aligns to a second which in turn aligns to a third, and so on, instead of all aligning to a datum—can destroy yields and even reliability.  Geometric Dimensioning & Tolerancing (GD&T) is one variant of this type of analysis.
