Card Edge Connectors - Adapters

1. Overview

Card Edge Connectors - Adapters are hybrid solutions combining printed circuit board (PCB) edge connectors with interface conversion capabilities. They enable direct board-to-board connections while facilitating protocol, form factor, or signal standard transitions. These components are critical in modern electronics for expanding functionality, enabling modular designs, and ensuring compatibility across generations of hardware architectures.

2. Main Types & Functional Classification

Type	Functional Characteristics	Application Examples
PCIe Expansion Adapters	High-speed protocol conversion (e.g., PCIe Gen4 to NVMe)	SSD storage expansion cards
Hybrid Memory Adapters	DRAM standard conversion (e.g., SODIMM to microDIMM)	Industrial computer upgrades
IO Interface Converters	Physical layer translation (e.g., SATA to M.2)	Embedded system integration
High-Speed Mezzanine	Parallel bus to serial protocol conversion	Telecom backplane systems

3. Structure & Components

Typical construction includes:

Stamped contact elements (phosphor bronze with gold plating)
High-temperature thermoplastic insulation (LCP or nylon 6T)
Anti-vibration polarization keying systems
