The **ATS-18B-174-C2-R0** is a high-performance electronic thermal management component, specifically a **heat sink** manufactured by Advanced Thermal Solutions (ATS). It is designed to dissipate heat from electronic components like BGA (Ball Grid Array) processors. --- ## 1. Technical Specifications The part number follows a specific nomenclature that defines its physical and thermal characteristics. | Feature | Specification | | :--- | :--- | | **Manufacturer** | Advanced Thermal Solutions, Inc. (ATS) | | **Base Dimensions** | 30.00mm x 30.00mm | | **Height** | 25.00mm | | **Material** | Aluminum (Anodized Blue) | | **Attachment Method** | pushPIN™ (Spring-loaded) | | **Thermal Resistance** | 4.02°C/W (at 1.0 m/s airflow) | | **Fin Type** | Fine Pitch (Grid Pattern) | --- ## 2. Key Electronic Components & Features ### A. pushPIN™ Attachment System Unlike adhesive-based heat sinks, the **C2-R0** variant uses a push-pin mechanism. This is critical for electronics because: * **Constant Pressure:** It ensures uniform contact between the heat sink and the chip, maximizing heat transfer. * **Reliability:** It prevents the heat sink from shifting during vibration or thermal cycling. * **Reusability:** The component can be removed for chip servicing without damaging the PCB. ### B. Thermal Interface Material (TIM) The "C2" in the part number indicates the presence of a **Pre-assembled Thermal Interface Material**. In this case, it usually refers to **T766** (a high-performance thermal pad/grease). This reduces the contact resistance between the electronic die and the aluminum base. ### C. Material Conductivity The heat sink is made of **6063 Aluminum**. While copper has higher conductivity, aluminum is preferred in this specific electronic application for its weight-to-performance ratio, preventing mechanical stress on the PCB solder joints. --- ## 3. Application Use Cases This component is typically found in the following electronic environments: 1. **Telecommunications:** Cooling FPGA and ASIC chips in routers. 2. **Industrial PCs:** Thermal management for embedded processors. 3. **Power Supplies:** Cooling MOSFETs or power modules that generate significant localized heat. --- ## 4. Performance at Different Airflows Thermal performance in electronics is measured by how much the temperature rises per Watt of power consumed (°C/W). | Airflow Velocity (m/s) | Thermal Resistance (°C/W) | | :--- | :--- | | 1.0 (Laminar) | 4.02 | | 2.0 (Turbulent) | 2.39 | | 3.0 (High Flow) | 1.97 |
