## ATS-11D-71-C2-R0: Technical Overview The **ATS-11D-71-C2-R0** is a high-performance electronic thermal management component, specifically a **Heat Sink** from Advanced Thermal Solutions (ATS). It is part of the "pushPIN™" series, designed for precision cooling of integrated circuits (ICs) and other electronic components. --- ### 1. Technical Specifications The following table highlights the core mechanical and thermal properties of this part: | Parameter | Specification | | :--- | :--- | | **Manufacturer** | Advanced Thermal Solutions (ATS) | | **Series** | pushPIN™ | | **Attachment Type** | Push-Pin (Spring-loaded) | | **Material** | Aluminum (Body) / Blue Anodized (Finish) | | **Dimensions (L x W)** | 45mm x 45mm | | **Height (Height Off Base)** | 30mm | | **Thermal Resistance** | 6.67 °C/W (at 100 LFM) | | **Flow Type** | Straight Fin | --- ### 2. Key Components & Design Features #### A. Fin Design The "Straight Fin" geometry is optimized for **unidirectional airflow**. The fins provide a high surface area to volume ratio, allowing heat to dissipate rapidly from the base plate to the surrounding air. #### B. Attachment Mechanism (pushPIN™) Unlike adhesive-based heat sinks, this part uses a mechanical push-pin system: * **Compression Springs:** Provide precise pressure to ensure a tight interface between the heat sink and the chip. * **Ease of Installation:** Allows for tool-free assembly and consistent mounting force, which prevents damage to delicate PCB traces. #### C. Thermal Interface Material (TIM) The "R0" suffix typically indicates that the part comes with **no pre-applied Thermal Interface Material**, or a standard non-silicon based pad, depending on the specific batch. Users generally apply high-performance thermal paste (like Arctic Silver or Shin-Etsu) during installation to fill microscopic air gaps between the component and the heat sink base. --- ### 3. Application Use Cases This specific heat sink is commonly used in electronic environments where space is moderate but cooling requirements are high: * **Networking Equipment:** Routers, switches, and high-speed gateways. * **Power Supplies:** Cooling MOSFETs or power regulators. * **Embedded Systems:** Industrial PCs and FPGA modules. --- ### 4. Thermal Performance Comparison (Calculated) Heat sinks behave differently based on the Airflow (LFM - Linear Feet per Minute): | Airflow (LFM) | Thermal Resistance (°C/W) | | :--- | :--- | | 100 (0.5 m/s) | 6.67 | | 300 (1.5 m/s) | 2.22 | | 500 (2.5 m/s) | 1.55 | ---
