1. Overview

Inline Module Sockets are electro-mechanical interfaces designed to connect memory modules (e.g., DRAM, SRAM) to printed circuit boards (PCBs). These connectors ensure reliable electrical conductivity, mechanical stability, and signal integrity in high-speed data transmission environments. They play a critical role in computing systems, telecommunications infrastructure, and industrial equipment by enabling modular memory upgrades and maintenance.

2. Main Types and Functional Classification

3. Structure and Composition

Typical components include:

• Contact points: Phosphor bronze or beryllium copper with gold plating
• Insulation housing: High-temperature resistant thermoplastics (LCP, PBT)
• Actuator mechanism: Z-axis compression system for secure module retention
• PCB termination: Through-hole or surface-mount solder tails

Advanced designs incorporate impedance-matched contacts and anti-vibration locking features.
