Backplanes are a type of electronic component that serve as a critical foundation within various electronic enclosures, boxes, and racks. Essentially, they are circuit boards containing slots into which additional electronic cards or modules can be inserted. The main function of a backplane is to provide a supportive base and electrical interconnections between these modules. This setup allows for high flexibility and scalability in electronic systems, enabling upgrades and expansions without redesigning the entire system.
The primary use of backplanes is found in applications requiring complex and high-speed data and signal processing, such as in computer servers, telecommunications equipment, and military electronics. Characteristics of backplanes include robust design, the ability to support numerous connection points, and compatibility with various signal types, which collectively enhance the performance and reliability of electronic assemblies. Notable manufacturers of backplanes include Amphenol, TE Connectivity, and Schroff.
