1. Overview

Specialized backplane connectors are critical electromechanical components designed to establish reliable interconnections between printed circuit boards (PCBs) in complex electronic systems. These connectors enable high-speed data transmission, power distribution, and signal integrity in demanding environments. Their importance spans industries such as telecommunications, industrial automation, and aerospace, where system reliability and performance are paramount.
