The **ATS-11B-70-C2-R0** is a specific electronic component belonging to the **Thermal Management** category. It is a high-performance heat sink manufactured by **Advanced Thermal Solutions (ATS)**, designed for cooling electronic components such as ICs (Integrated Circuits), BGA (Ball Grid Array) packages, and processors. --- ### 1. Technical Specifications The model number provides specific details about its physical and thermal characteristics: | Feature | Specification | | :--- | :--- | | **Manufacturer** | Advanced Thermal Solutions (ATS) | | **Series** | pushPIN™ | | **Base Dimensions** | 45mm x 45mm | | **Height** | 25mm | | **Material** | Aluminum (AL6063) | | **Finish** | Blue Anodized | | **Attachment Method** | pushPIN™ (Spring-loaded pins) | | **Thermal Resistance** | 1.20°C/W (at 200 LFM) | --- ### 2. Key Design Elements #### A. Fin Pattern (Cross-Cut) This unit features a **cross-cut** fin design. Unlike straight-fin heat sinks, the cross-cut pattern allows for air to flow from multiple directions. This makes it highly efficient in "crowded" PCB environments where airflow might be turbulent or non-linear. #### B. pushPIN™ Attachment The "C2" in the part number indicates the specific attachment kit. This system uses: * **Compression Springs:** Provide precise pressure to ensure optimal thermal contact between the heat sink and the chip. * **Plastic/Brass Pins:** Secure the unit through pre-drilled holes in the PCB. #### C. Thermal Interface Material (TIM) Usually, these parts come with a pre-applied **Phase Change Material** or thermal tape. For the R0 variant, it typically features **T766** thermal interface material, which fills microscopic air gaps to improve heat transfer efficiency. --- ### 3. Application Use-Cases This heat sink is typically used in the following electronic sectors: 1. **Telecommunications:** Cooling for high-speed routers and switches. 2. **Embedded Systems:** Industrial PCs and automation controllers. 3. **Power Electronics:** Dissipating heat from voltage regulators or power modules. --- ### 4.
