The **ATS-18B-148-C2-R0** is a high-performance heat sink manufactured by **Advanced Thermal Solutions (ATS)**. It is part of the "push pin" series designed to provide efficient cooling for electronic components like processors, ASICs, and FPGAs. --- ### 1. Technical Specifications Below are the primary physical and thermal characteristics of this component: | Feature | Specification | | :--- | :--- | | **Dimensions** | 30mm x 30mm x 15mm | | **Material** | Aluminum (Al6063) | | **Finish** | Blue Anodized | | **Attachment Type** | Push Pin (Brass) | | **Spring Type** | Compression Spring | | **Thermal Resistance** | 8.70°C/W (at 200 LFM) | | **Flow Orientation** | Square (Omni-directional) | --- ### 2. Breakdown of the Model Number The part number follows a specific nomenclature used by Advanced Thermal Solutions: * **ATS:** Manufacturer (Advanced Thermal Solutions). * **18B:** Indicates the specific series and mounting hole pattern. * **148:** Unique identifier for physical dimensions/fin design. * **C2:** Refers to the material and finish (Blue Anodized Aluminum). * **R0:** Revision code (Standard version). --- ### 3. Key Features * **Omni-directional Fins:** The "cross-cut" fin design allows air to flow through the heat sink from any direction, making it ideal for systems where the airflow direction might be unpredictable or constrained. * **Mechanical Attachment:** Unlike adhesive tapes, the push pin and spring mechanism provide a constant, high pressure against the electronic component, ensuring better thermal contact and reliability during vibration. * **Thermal Interface Material (TIM):** Typically, these come pre-applied with high-performance thermal tape or grease to simplify the assembly process. --- ### 4. Implementation Example When integrating this into a PCB design, you must ensure the board has the correct hole spacing to accommodate the push pins. ```c // Design Clearance Note // -------------------- // Footprint: 30x30mm // Hole Diameter: ~3.0mm (standard for ATS Push Pins) // Keep-out Zone: Add 2mm buffer around the perimeter for spring clips. ```
