Samtec Flyover Copper Cable Assemblies

Main Title

Flyover copper cable assemblies

Mixed Media

As bandwidth requirements rapidly increase, routing signals through lossy PCBs, vias and other components has become one of the most complex challenges designers face. Samtec’s “Flyover” design approach breaks the constraints of traditional signalling substrate and hardware offerings, resulting in a cost-effective, high-performance answer to the challenges of 28 Gbps bandwidths and beyond.

Samtec direct connect cable system is a cost effective solution for high-speed boardto-board or flyover applications. The high retention press fit termination provided direct attach to the PCB eliminating the additional cost of board-level connectors.

The direct attach flyover QSFP28 cable assembly flies critical high-speed signals over the PCB for improved and extended signal integrity.
