The **ATS-20B-70-C2-R0** is a high-performance thermal management component manufactured by **Advanced Thermal Solutions (ATS)**. Specifically, it is a push-pin style heat sink designed for cooling electronic components such as CPUs, GPUs, or high-power ASICs. ### 1. Technical Specifications The following table summarizes the primary physical and thermal characteristics of the part: | Characteristic | Specification | | :--- | :--- | | **Part Number** | ATS-20B-70-C2-R0 | | **Material** | Aluminum | | **Finish** | Blue Anodized | | **Base Dimensions** | 45mm x 45mm | | **Height** | 25mm | | **Attachment Type** | Push-Pin (Plastic) | | **Spring Type** | Compression Spring | | **Thermal Interface Material (TIM)** | T766 (Pre-applied) | --- ### 2. Electronic & Thermal Performance The "parts" of this component work together to manage the thermal output of an electronic circuit. Here is a breakdown of its cooling efficiency based on airflow (LFM - Linear Feet per Minute): * **Thermal Resistance (Unducted):** * @ 200 LFM: **3.43 °C/W** * @ 500 LFM: **1.63 °C/W** * @ 800 LFM: **1.21 °C/W** * **Fin Design:** It utilizes a **Straight Fin** geometry, which is ideal for high-velocity airflow environments where air can be forced through the channels efficiently. --- ### 3. Component Breakdown The ATS-20B-70-C2-R0 is comprised of four primary sub-components: 1. **The Heat Sink Body:** Made of extruded aluminum, providing a large surface area for heat dissipation. The blue anodized finish increases emissivity and protects against corrosion. 2. **Push-Pins:** These are the mechanical fasteners (usually nylon or plastic) that secure the heat sink to the PCB through pre-drilled holes. 3. **Compression Springs:** These ensure "High-Back" pressure, maintaining constant contact between the heat sink base and the electronic component (die) to minimize thermal resistance. 4. **T766 Phase Change Material:** This is the thermal paste/pad pre-applied to the bottom. It fills microscopic air gaps between the component and the heat sink. --- ### 4.
