1. CUI0987BB514B is an x8-lane high-speed connector that complies with the PCI-SIG CEM 5.0 specification. It adopts a 98-pin configuration and SMT (Surface Mount Technology) process, with the core feature of "with rear wing" structural design, specifically designed for mid-to-high-end high-performance scenarios.
2. It is suitable for devices that have high requirements for bandwidth, installation stability, and space compatibility, such as AI accelerator cards, multi-drive NVMe SSD arrays, and 1U servers.
3. It complies with the RoHS environmental standard and halogen-free, lead-free specifications, balancing performance and green production requirements.
◆◆ Product Advantage
1. Structural Innovation: Rear Wing Design Enhances Installation Stability and Positioning AccuracyThe rear wing is made of UL94V-0 grade high-temperature plastic, which can be accurately engaged with the PCB board during installation, with positioning error controlled within ±0.1mm, avoiding connector displacement caused by vibration after SMT (Surface Mount Technology) soldering. At the same time, the rear wing enhances the mechanical connection strength between the connector and the PCB, increasing the pull-out force by 30%, making it suitable for long-term high-vibration scenarios such as industrial equipment and servers.
2. Visualization and Foolproof AssistanceThe rear wing offers two color options: black and blue 661C. Different colors can be used to distinguish connectors of different channels or functions, reducing the misinstallation rate during multi-device integration. Additionally, the rear wing structure forms mechanical foolproofing with the device interface, preventing damage to the gold finger caused by reverse insertion.
3. Signal Integrity AssuranceThe terminals adopt a phosphor bronze base material + gold/nickel plating process to reduce signal transmission loss. Combined with the "reflow soldering at 260℃ for 3-5 seconds" process recommended in the document, the soldering yield rate reaches over 99.5%, avoiding signal interruption caused by cold soldering and ensuring insertion loss ≤ -36dB @ 16GHz within a transmission distance of 1.5 meters.
4. Durable Material SelectionThe terminals are made of phosphor bronze (with excellent corrosion resistance and elasticity), and the surface plating combination (base nickel + matte tin + gold plating) can withstand 50 insertion-extraction cycles while maintaining contact resistance ≤ 50mΩ. Both the housing and the rear wing are made of UL94V-0 grade high-temperature plastic, which will not deform when used in a 105℃ environment for a long time, avoiding structural failure caused by high temperatures.
5. Strict Mechanical ParametersThe terminal retention force is ≥ 3.43N, far exceeding the 2.5N standard of conventional connectors, preventing terminal loosening. The performance of withstanding 50 insertion-extraction cycles meets the repeated insertion needs during later equipment maintenance and upgrades, reducing replacement costs.
6. Adaptation to Extreme EnvironmentsWith a wide operating temperature range of -40℃ to 105℃, it covers scenarios such as industrial low-temperature workshops (e.g., cold chain control equipment) and high-temperature server rooms. There is no performance degradation during low-temperature startup and no parameter drift during high-temperature operation.
7. Environmental ComplianceIt complies with the RoHS directive and halogen-free, lead-free specifications, with heavy metal (lead, cadmium, etc.) content below 1000ppm, meeting the environmental requirements of regions such as the European Union and China.
