The **ATS-02A-55-C2-R0** is a specific electronic component categorized as a **High-Performance Heat Sink**, manufactured by Advanced Thermal Solutions (ATS). It is designed to dissipate heat from electronic integrated circuits (ICs) like CPUs, GPUs, or FPGAs. --- ## 1. Technical Specifications The following table outlines the physical and thermal characteristics of this part: | Feature | Specification | | :--- | :--- | | **Manufacturer** | Advanced Thermal Solutions (ATS) | | **Material** | Aluminum | | **Finish** | Blue Anodized | | **Dimensions (L x W x H)** | 40mm x 40mm x 10mm | | **Attachment Method** | pushPIN™ | | **Fin Style** | Straight Fin | | **Thermal Resistance** | 23.98°C/W (Natural Convection) | --- ## 2. Key Component Features ### A. pushPIN™ Attachment System One of the most significant aspects of this part is the **pushPIN™** mounting mechanism. Unlike adhesive-based heat sinks, this uses: * **Brass Springs:** Provides precise pressure to ensure optimal thermal contact. * **Plastic/Brass Pins:** Secure the heat sink through pre-drilled holes in the PCB. * **Reliability:** It is more robust against mechanical shock and vibration compared to "peel-and-stick" solutions. ### B. Material and Coating * **Aluminum 6063:** Chosen for its high thermal conductivity and lightweight properties. * **Blue Anodization:** Not just for aesthetics; the anodized layer provides electrical insulation and improves corrosion resistance. ### C. Thermal Interface Material (TIM) The part typically comes with a **Pre-applied Thermal Interface Material**. This eliminates the need for manual application of thermal paste, ensuring a consistent and thin layer for maximum heat transfer from the chip to the aluminum fins. --- ## 3. Performance Data Thermal performance is dependent on the airflow (Linear Feet per Minute - LFM) within the electronics enclosure: | Airflow (LFM) | Velocity (m/s) | Thermal Resistance (°C/W) | | :--- | :--- | :--- | | 100 | 0.5 | 23.98 | | 300 | 1.5 | 9.07 | | 500 | 2.5 | 6.20 | | 700 | 3.5 | 5.05 | --- ## 4.
