1. Overview

Backplane connectors are critical components in electronic systems, providing modular interconnection between printed circuit boards (PCBs) and supporting high-density signal/power transmission. Accessories enhance their functionality through mechanical support, environmental protection, and performance optimization. These components are essential in telecommunications, data centers, and industrial equipment for ensuring reliable system architecture.
