Memory Connectors
Memory Connectors are electronic components specifically used to connect memory modules to motherboards. Their design directly affects the stability and efficiency of memory data transmission.
1. What are Memory Connectors?
Memory Connectors are a type of electronic connector. Their main function is to provide a detachable physical interface to ensure reliable high-speed signal transmission between memory modules (such as DRAM, SDRAM, etc.) and motherboards or other processing units. Such connectors usually have high-density layout characteristics and are suitable for the compact requirements of modern computer systems.
2. What are the Core Features of Memory Connectors?
1) Mechanical Performance
Plug-in and Pull-out Times: The durability standard usually reaches more than 25 times to ensure long-term reliability.
Structural Design: The latch structure (such as the Natural latch) and the PCB locator design enhance the alignment accuracy and retention during mating.
Pitch Specifications: Both the mating interface and the terminal interface use a 0.60mm pitch to adapt to high-density circuit layouts.
2) Electrical Performance
Contact Plating: 0.762µm gold plating is used for the joint part, and 2.540µm tin plating is used for the termination part to balance conductivity and cost.
Operating Temperature: Supports a wide temperature range of -10°C to 85°C, suitable for different environmental scenarios.
Signal Integrity: Optimized impedance matching and shielding design to reduce interference in high-speed signal transmission.
3) Material and Safety
Flame Retardancy: The shell adopts 94V-0 grade flame retardant materials (such as high-temperature thermoplastic resin) to improve safety.
Metal Parts: Copper alloy substrate combined with a surface treatment process to ensure corrosion resistance and mechanical strength.
3. What are Memory Connectors Used for?
Server/Data Center: Support high-frequency memory modules (such as DDR5) to meet large-capacity data processing needs.
Consumer Electronics: Applied to laptops, smartphones, and other devices, emphasizing lightness and high reliability.
Industrial Control: Adapt to wide temperature and high vibration environments, such as industrial control motherboards and embedded systems.
4. Technology Trends of Memory Connectors
High-speed: With the popularization of PCIe 5.0 and higher standards, connectors need to support higher frequencies (such as 56 Gbps and above).
Low-power Design: Optimize contact resistance and plating process to reduce overall energy consumption.
Modular Compatibility: Adapt to various memory specification upgrade requirements through standardized interface design (such as DIMM/SO-DIMM).
