chassisbackplanes
A chassis backplane is a printed circuit assembly located inside a chassis that provides the electrical interconnections between the system’s components and expansion cards. It serves as a centralized backbone for data and power distribution, enabling multiple devices such as processors, memory, storage controllers, and peripheral cards to connect and communicate without individual point-to-point wiring.
Backplanes are typically categorized as passive or active. A passive backplane contains mainly connectors and interconnect
Common configurations include fixed-slot backplanes that accept a defined set of expansion cards or drives, and
Design considerations for chassis backplanes encompass electrical, mechanical, and thermal aspects. Impedance-controlled high-speed traces, adequate power
