The **M2ADS-1A14-R2** is a specialized electronic component, typically categorized as a high-density, high-speed connector or a specific power module interface used in server and networking hardware. --- ### 1. General Specifications While specific datasheets are often proprietary to manufacturers like **Foxconn** or **Amphenol** (who produce these for server OEMs), the "M2ADS" series generally follows these characteristics: | Feature | Specification | | :--- | :--- | | **Type** | High-speed Mezzanine Connector / Power Interface | | **Mounting Type** | Surface Mount (SMT) or Press-fit | | **Pitch** | Typically 0.5mm to 1.0mm | | **Material** | High-temperature thermoplastic (LCP) | | **Contact Plating** | Gold (Au) over Nickel (Ni) | --- ### 2. Key Electronic Components & Materials The part is comprised of several critical electronic sub-elements: 1. **Conductive Contacts:** * Made from Copper Alloy for high conductivity. * Designed for low contact resistance to ensure minimal signal loss. 2. **Insulator Body:** * Liquid Crystal Polymer (LCP) is used to withstand lead-free reflow soldering temperatures (up to 260°C). 3. **EMI Shielding:** * Often includes metal "shells" or integrated ground planes to reduce electromagnetic interference in high-frequency environments. 4. **Solder Charge/Balls:** * The "R2" suffix often denotes a specific revision or packaging style (like Tape & Reel) and may include pre-applied solder for BGA-style attachment. --- ### 3. Applications This part is typically found in the following hardware environments: * **Blade Servers:** Used as the bridge between a mezzanine card (like a NIC or HBA) and the motherboard. * **Networking Switches:** High-density interconnects for daughterboards. * **Storage Arrays:** Connection points for high-speed backplanes. --- ### 4. Technical Handling Precautions When dealing with the M2ADS-1A14-R2, engineers must observe the following: ```markdown * ESD Protection: Use grounded wrist straps; the fine-pitch pins are sensitive to static. * Coplanarity: Ensure the PCB is flat; even 0.1mm of warp can cause open solder joints. * Inspection: Use X-ray inspection for BGA/SMT variants to verify hidden solder joints. ```
