The Fiber Weave Skew Problem Is Over: ACCM Celeritas™ SF1600 Delivers Zero-Skew for PCIe 7, 224 Gbps and Beyond
Advanced Chip & Circuit Materials, Inc. (ACCM) today introduced Celeritas SF1600, a laminate and prepreg material that eliminates fiber weave skew at its root. Fiber weave skew is a materials problem, not a routing one. Woven glass creates a spatially periodic dielectric in which differential pairs travel alternately through resin-rich and glass-rich regions. In a differential pair, the two conductors traverse different paths, which produces a time delay (skew) that panel rotation, serpentine routing, or zig-zag compensation cannot address at 224 Gbps PAM4 and beyond. Celeritas SF1600 removes the cause entirely through ACCM’s proprietary resin and reinforcement technologies, delivering validated zero-skew performance and the lowest dielectric loss in its class – on standard FR-4 equipment with no special handling, storage, or infrastructure.
