Abstract
In one embodiment, an apparatus includes a plurality of layers in a circuit board, each of the layers comprising a fiber weave, two plated holes extending through the layers and connecting two or more of the layers, and a non-plated hole interposed between the plated holes. The non-plated hole passes through a potential CAF (Conductive Anodic Filament) migration path along the fiber weave to prevent CAF formation between the plated holes.
