The **M2SBS-114-R2** is a specific electronic hardware component, typically identified as a **high-precision, surface-mount standoff** or a specialized **M.2 mechanical spacer/nut**. These are primarily used in the assembly of printed circuit boards (PCBs) to secure M.2 modules (like NVMe SSDs or Wi-Fi cards). Below is a detailed breakdown of its electronic and mechanical specifications. --- ### 1. General Specifications | Feature | Description | | :--- | :--- | | **Component Type** | SMT (Surface Mount Technology) Standoff | | **Standard** | M.2 (NGFF) Hardware Accessory | | **Material** | Usually Brass or Steel with Tin/Nickel plating | | **Mounting Type** | Surface Mount (Soldered directly to the PCB) | | **Thread Size** | M2 x 0.4 | ### 2. Key Electronic & Mechanical Functions * **Electrical Grounding:** Since the part is soldered to the PCB's ground plane and screwed into the M.2 card, it provides a low-resistance path for **EMI (Electromagnetic Interference)** shielding and grounding. * **Structural Support:** It maintains the specific height (usually 2mm to 4mm depending on the "R" suffix) required to keep the M.2 card parallel to the motherboard, preventing bending or stress on the gold-finger connector. * **Heat Dissipation:** While not a primary heatsink, the metal construction helps conduct some thermal energy from the module into the PCB ground layers. ### 3. Assembly Integration In a manufacturing environment, the M2SBS-114-R2 is handled as follows: 1. **Pick and Place:** The part often comes in "Tape and Reel" packaging with a Kapton polyimide patch on top so vacuum nozzles can lift it. 2. **Reflow Soldering:** It is placed on solder paste on the PCB. During the reflow oven cycle, it becomes a permanent part of the board. 3. **Final Assembly:** An M2 screw is driven into the internal threads of this part to lock the SSD/Module in place. ### 4. Part Number Breakdown (Typical) * **M2:** Refers to the metric thread size (2mm). * **SBS:** Often denotes "Surface Board Spacer" or "Solderable Board Standoff." * **114:** Typically refers to the specific height or series series dimensions. * **R2:** Usually indicates a revision or a specific height variant (e.g., 2.0mm height). --- ### Technical Summary This part is critical for **modern computing hardware**. Without this component, an M.2 drive cannot be securely fastened, leading to potential data loss if the drive vibrates loose or electrical shorts if the drive touches other components on the motherboard.
