The **ATS-20F-150-C2-R0** is a high-performance electronic thermal management component, specifically a **Heat Sink** manufactured by Advanced Thermal Solutions (ATS). It is designed for the cooling of electronic components such as CPUs, GPUs, FPGAs, and power modules. --- ### 1. Technical Specifications The part number follows a specific nomenclature that defines its physical and thermal characteristics. | Feature | Specification | | :--- | :--- | | **Manufacturer** | Advanced Thermal Solutions (ATS) | | **Material** | Aluminum | | **Finish** | Blue Anodized | | **Attachment Method** | pushPIN™ | | **Thermal Resistance** | 1.60°C/W (at 200 LFM) | | **Dimensions (L x W)** | 45mm x 45mm | | **Height** | 25mm | | **Fin Style** | XC-CUT (Cross-Cut) | --- ### 2. Key Electronic Features #### A. pushPIN™ Attachment System Unlike traditional adhesive-based heat sinks, this model uses a **pushPIN™** system. This involves a pre-drilled hole pattern on the PCB where a spring-loaded pin secures the heat sink. * **Benefits:** Ensures consistent pressure (clamping force) across the component for better thermal transfer and prevents the heat sink from shifting during vibration or shipping. #### B. Cross-Cut (XC-CUT) Fin Design The fins are not just parallel lines; they are cut in a grid-like pattern. * **Efficiency:** This design allows for "omni-directional" airflow. It can dissipate heat effectively regardless of which direction the cooling fan is blowing, making it ideal for crowded PCB environments. #### C. Thermal Interface Material (TIM) This specific model usually comes with a pre-applied **T766** thermal phase-change material or a high-performance thermal pad. This ensures there are no microscopic air gaps between the electronic chip and the aluminum base. --- ### 3. Application Use Cases This part is commonly found in: 1. **Telecommunications:** Cooling high-speed switching silicon. 2. **Industrial Controls:** Managing heat in motor drivers or power converters. 3. **Embedded Computing:** Protecting processors in fanless or restricted-airflow enclosures. --- ### 4. Thermal Performance Comparison Thermal resistance ($R_{th}$) determines how many degrees the component temperature rises per Watt of power dissipated. | Airflow (LFM) | Velocity (m/s) | Thermal Resistance (°C/W) | | :--- | :--- | :--- | | 100 | 0.5 | 3.22 | | 200 | 1.0 | 1.60 | | 400 | 2.0 | 1.11 |
