The **ATS-55270K-C2-R0** is a high-performance heat sink component designed by Advanced Thermal Solutions (ATS). It is specifically engineered for cooling electronic components such as BGAs (Ball Grid Arrays) and processors. --- ### 1. Technical Specifications Below are the primary physical and thermal characteristics of the part: | Feature | Specification | | :--- | :--- | | **Part Number** | ATS-55270K-C2-R0 | | **Heat Sink Type** | maxiFLOW™ | | **Attachment Method** | maxiGRIP™ (Frame Clip) | | **Dimensions** | 27.00mm x 27.00mm | | **Height** | 14.50mm | | **Material** | Aluminum | | **Finish** | Blue Anodized | | **Thermal Resistance** | 5.20° C/W (Natural Convection) | --- ### 2. Key Electronic Design Components #### A. The maxiFLOW™ Fin Design The heat sink features a graduated fin profile. This design is critical for electronics because it: * Reduces pressure drop. * Increases surface area for heat dissipation. * Optimizes airflow in constrained PCB environments. #### B. The maxiGRIP™ Attachment System One of the most important "parts" of this assembly is the attachment mechanism. Unlike permanent adhesives, it uses: * **Plastic Frame Clip:** Replaces the need for holes in the PCB. * **Stainless Steel Spring Clip:** Provides steady pressure (Normal Force) to ensure the Thermal Interface Material (TIM) works effectively between the chip and the heat sink. #### C. Thermal Interface Material (TIM) The "C2" in the part number typically refers to the pre-applied thermal interface material. * **Component:** This part usually comes with **Chomerics T766** or a similar high-performance phase-change material. * **Function:** It fills microscopic air gaps between the electronic chip surface and the aluminum heat sink to maximize heat transfer. --- ### 3. Application Use Cases This specific part is used in the following electronic sectors: 1. **Telecommunications:** Cooling high-speed networking chips. 2. **Embedded Systems:** Protecting industrial CPUs from thermal throttling. 3. **Power Electronics:** Managing heat in compact voltage regulation modules. --- ### 4. Mounting Guide (Example) To integrate this into a PCB design, the following workflow is used: ```markdown 1. Place the plastic maxiGRIP™ frame around the electronic component. 2. Apply the heat sink (with pre-applied TIM) onto the component. 3. Use the installation tool to snap the wire clip into the frame. 4. The constant tension ensures thermal contact even under vibration. ```
