The **ATS-03F-71-C3-R0** is a high-performance electronic thermal management component, specifically a **Heat Sink** manufactured by Advanced Thermal Solutions (ATS). It is part of the "push-pin" series designed for securing cooling solutions directly to Printed Circuit Boards (PCBs). ### 1. Technical Specifications Below are the primary physical and thermal characteristics of the component: | Feature | Specification | | :--- | :--- | | **Material** | Aluminum (Blue Anodized) | | **Fin Type** | Straight Fin | | **Attachment Method** | Push-Pin (Plastic) | | **Dimensions** | 45mm x 45mm x 30mm | | **Thermal Resistance** | 6.77 °C/W (at 100 LFM) | | **Pressure Drop** | 0.12 in. H2O (at 100 LFM) | | **Thermal Interface (TIM)** | T412 (Chomerics) | --- ### 2. Component Composition This part is an assembly of several specialized electronic materials: * **Heat Sink Body:** Extruded aluminum designed for optimal surface area. The blue anodized finish provides corrosion resistance and increased emissivity. * **Push-Pins:** Plastic (usually Nylon) fasteners that provide a constant force against the chip to ensure consistent thermal contact. * **Springs:** Compressed springs on the push-pins that maintain the required downward pressure. * **Thermal Interface Material (TIM):** Pre-applied T412 material. This is a phase-change or conductive pad that fills microscopic air gaps between the component (CPU/GPU) and the heat sink. --- ### 3. Application and Use Cases This heat sink is typically used in industrial and telecommunications hardware where passive cooling is insufficient and airflow is present within the chassis. * **BGA Cooling:** Primarily used for Ball Grid Array (BGA) components like FPGAs, ASICs, and high-speed processors. * **High Airflow Environments:** Optimized for systems with internal fans (measured in Linear Feet per Minute - LFM). * **PCB Integration:** The push-pin design requires pre-drilled holes in the PCB, offering a more secure mechanical bond than simple adhesive "peel-and-stick" heat sinks. --- ### 4. Cooling Efficiency (Thermal Performance) The efficiency of the ATS-03F-71-C3-R0 is highly dependent on the velocity of the air passing through the fins: ```json { "Airflow_LFM": [100, 200, 300, 400, 500], "Thermal_Resistance_CW": [6.77, 4.17, 3.04, 2.42, 2.04] } ``` *(Note: As airflow increases, thermal resistance decreases, allowing the heat sink to dissipate heat more effectively.)* ---
