## Technical Overview: ATS-20B-40-C2-R0 The **ATS-20B-40-C2-R0** is a high-performance electronic thermal management component, specifically a **Pin Fin Heat Sink** manufactured by *Advanced Thermal Solutions (ATS)*. It is designed for cooling electronic components like CPUs, GPUs, or power modules in environments with constrained airflow. --- ### 1. Key Technical Specifications | Feature | Specification | | :--- | :--- | | **Part Number** | ATS-20B-40-C2-R0 | | **Heat Sink Type** | Pin Fin (cross-cut style) | | **Material** | Aluminum | | **Finish** | Blue Anodized | | **Attachment Method** | pushPIN™ (Spring-loaded) | | **Thermal Resistance** | 1.80° C/W @ 200 LFM | | **Dimensions (L x W x H)** | 40mm x 40mm x 25mm | --- ### 2. Physical Design & Composition The "electronic parts" of this assembly are not active circuitry, but rather precision-engineered mechanical components that facilitate heat transfer: * **The Heat Sink Body:** Constructed from high-grade aluminum. The "Pin Fin" design increases the surface area significantly compared to flat blocks, allowing air to circulate from any direction (omni-directional). * **The Interface Material:** These units typically come with a pre-applied **Thermal Interface Material (TIM)** on the base to fill microscopic air gaps between the chip and the heat sink. * **pushPIN™ Mounting System:** Unlike simple adhesive tapes, this part uses a mechanical fastening system consisting of: * **Brass/Plastic Push Pins:** To secure the sink to the PCB. * **Stainless Steel Springs:** To provide consistent downward pressure, ensuring optimal thermal contact. --- ### 3. Part Number Breakdown (Nomenclature) Understanding the suffix codes helps identify the specific variant: 1. **ATS-20:** Series designation (Pin Fin). 2. **B:** Specific fin geometry/pattern. 3. **40:** Size (Width/Length in mm). 4. **C2:** Material/Finish code (Blue Anodized). 5. **R0:** Revision or packaging code. --- ### 4. Thermal Performance Data Performance varies based on the airflow (measured in Linear Feet per Minute - LFM): | Airflow Velocity | Thermal Resistance (°C/W) | | :--- | :--- | | **Unducted (200 LFM)** | 1.80 | | **Ducted (400 LFM)** | 1.20 | | **Static / Natural Convection** | 12.00+ | --- ### 5. Application Areas * **Networking Gear:** Switches and routers where airflow is often turbulent. * **Industrial PCs:** Small form factor boards requiring high reliability. * **Power Supplies:** Cooling MOSFETs or Voltage Regulators.
