The **ATS-20B-75-C1-R0** is a high-performance electronic thermal management component, specifically a **push-pin heat sink** designed for cooling integrated circuits (ICs) and other electronic components. --- ## 1. Technical Specifications The part number follows a specific nomenclature from the manufacturer, **Advanced Thermal Solutions (ATS)**. | Feature | Specification | | :--- | :--- | | **Manufacturer** | Advanced Thermal Solutions, Inc. | | **Series** | pushPIN™ Heat Sink | | **Material** | Aluminum | | **Finish** | Blue Anodized | | **Attachment Method** | Push-Pin (Plastic or Brass) | | **Thermal Resistance** | 1.47°C/W (at 200 LFM) | | **Dimensions** | 25mm x 25mm x 30mm | --- ## 2. Key Electronic Components & Features ### A. The Heat Sink Body * **High Aspect Ratio:** The fins are designed with a "straight fin" or "cross-cut" pattern to maximize surface area within a small footprint (25mm x 25mm). * **Aluminum Construction:** Extruded aluminum is used for its high thermal conductivity and lightweight properties, ensuring heat is moved away from the semiconductor junction quickly. ### B. The Attachment Mechanism (Push-Pins) The "B" and "75" segments of the part number signify the mounting hardware: * **Compression Springs:** These ensure consistent pressure (load) is applied to the electronic chip, which is critical for maximizing thermal interface performance. * **Push-Pins:** These provide a secure mechanical connection to the PCB, preventing the heat sink from shifting during vibration or shipping. ### C. Thermal Interface Material (TIM) * **Pre-applied TIM:** This model usually comes with a pre-applied thermal pad or phase-change material on the base. * **Function:** It fills microscopic air gaps between the electronic component (CPU, FPGA, or GPU) and the heat sink base to lower thermal resistance. --- ## 3. Application Use Cases This specific part is typically found in: 1. **Telecommunications:** Cooling high-speed processors in routers and switches. 2. **Embedded Systems:** Industrial PCs where space is limited but vertical clearance (30mm height) is available. 3. **Power Electronics:** Cooling MOSFETs or power regulators that generate significant heat in a small package. --- ## 4.
