Key Technical Specifications | Parameter | Specification | | :--- | :--- | | **Manufacturer** | Advanced Thermal Solutions (ATS) | | **Part Number** | ATS-20F-142-C2-R0 | | **Material** | Aluminum (Blue Anodized) | | **Attachment Method** | Push-Pin (Plastic) | | **Footprint / Dimensions** | 45.00mm x 45.00mm | | **Height** | 23.00mm | | **Thermal Resistance** | 3.22°C/W @ 200 LFM | | **Spring Type** | Compression Spring | --- ### 2. Design and Engineering Features #### A. maxiFLOW™ Fin Geometry The "F" in the part number indicates the **maxiFLOW™** design. Unlike standard straight-fin heat sinks, this design features a tapered fin structure. * **Purpose:** Increases surface area while maintaining a low pressure drop. * **Benefit:** Allows for maximum heat dissipation in constrained airflow environments. #### B. Attachment Mechanism (Push-Pin) This specific model uses a **Plastic Push-Pin** system with a compression spring. * **Installation:** The pins are inserted through pre-drilled holes in the PCB. * **Force:** The compression spring ensures a consistent downward pressure (interface pressure) between the heat sink base and the electronic component, optimizing thermal transfer. #### C. Material and Coating * **Aluminum 6063:** Provides high thermal conductivity and is lightweight. * **Blue Anodized Finish:** Not only provides aesthetic appeal but also adds a layer of corrosion resistance and slightly improves radiative heat transfer. --- ### 3. Thermal Performance Analysis The performance of this heat sink is dependent on the airflow velocity (LFM - Linear Feet per Minute). | Airflow Velocity (LFM) | Thermal Resistance (°C/W) | | :--- | :--- | | 200 | 3.22 | | 300 | 2.40 | | 400 | 2.00 | | 500 | 1.80 | --- ### 4. Implementation Checklist When integrating the ATS-20F-142-C2-R0 into a PCB design, ensure the following: 1. **PCB Hole Pattern:** The board must have holes positioned to match the push-pin spread. 2. **TIM (Thermal Interface Material):** This part usually comes with a pre-applied high-performance thermal phase-change material or requires a separate pad/paste. 3. **Keep-out Zone:** Ensure no surface-mount components (SMD) are placed under the footprint of the heat sink wings. ---
