Glass-weave skew additional description
The impact of glass-weave skew on Signal Integrity (SI) is magnified by exponentially increasing bit rates, but is ultimately driven by two competing factors:
The need for near-complete symmetry between two halves of a differential pair
non-uniform microenvironments across dielectric materials
This white paper provides an in-depth description of the sources of this skew and presents 11 techniques that can be used to control glass-weave skew in a PCB.
