The **ATS-20A-159-C2-R0** is a high-performance electronic thermal management component, specifically a **push-pin style heat sink** designed for cooling integrated circuits (ICs) such as CPUs, GPUs, or FPGAs. It is manufactured by Advanced Thermal Solutions (ATS). --- ### 1. Technical Specifications The part is defined by its physical dimensions and thermal properties. Below are the key specifications: | Feature | Specification | | :--- | :--- | | **Material** | Aluminum (Al) | | **Finish** | Blue Anodized | | **Dimensions (L x W x H)** | 45.00mm x 45.00mm x 20.00mm | | **Attachment Method** | Push-Pin (Brass) | | **Spring Type** | Compression Spring | | **Thermal Resistance** | ~1.00°C/W (varies with airflow) | | **Pattern** | Fine Pitch (straight fin) | --- ### 2. Physical Design Components This assembly consists of three main electronic/mechanical sub-parts: 1. **Heat Sink Body:** A block of aluminum with extruded fins. Aluminum is chosen for its high thermal conductivity and lightweight properties. 2. **Push-Pins:** These are the mechanical fasteners that secure the heat sink to the Printed Circuit Board (PCB). They are designed for standardized 3.0mm holes. 3. **Springs:** High-tension compression springs ensure constant, uniform pressure between the heat sink and the electronic component to maximize heat transfer. 4. **Thermal Interface Material (TIM):** This part usually comes pre-applied with **T766** phase-change material or a similar thermal pad on the base to fill microscopic air gaps between the chip and the metal. --- ### 3. Thermal Performance Analysis The efficiency of the ATS-20A-159-C2-R0 depends heavily on the velocity of the air (measured in Linear Feet per Minute - LFM) passing through the fins. | Airflow Velocity (LFM) | Thermal Resistance (°C/W) | | :--- | :--- | | **200 LFM** | 3.82 | | **400 LFM** | 2.15 | | **600 LFM** | 1.62 | | **800 LFM** | 1.34 | --- ### 4. Part Number Breakdown The part number follows a specific nomenclature used by Advanced Thermal Solutions: * **ATS:** Manufacturer prefix. * **20A:** Series designation (height/fin style). * **159:** Unique footprint code (45x45mm). * **C2:** Material/Finish code (Blue Anodized). * **R0:** Revision/Packaging indicator.
