The **ATS-20D-72-C2-R0** is a high-performance electronic thermal management component, specifically a **Heat Sink** manufactured by Advanced Thermal Solutions (ATS). It is part of the "push pin" series designed for cooling integrated circuits (ICs) and other electronic surface-mount components. --- ### 1. Technical Specifications The following table outlines the physical and thermal properties of this specific part: | Parameter | Specification | | :--- | :--- | | **Manufacturer** | Advanced Thermal Solutions Inc. (ATS) | | **Material** | Aluminum | | **Finish** | Blue Anodized | | **Dimensions (L x W x H)** | 45mm x 45mm x 15mm | | **Thermal Resistance** | 5.11°C/W (at 100 LFM) | | **Attachment Method** | Push-Pin (Brass) | | **Spring Type** | Compression Spring | | **TIM (Thermal Interface Material)** | T766 (Pre-applied) | --- ### 2. Key Electronic Features #### A. Thermal Interface Material (TIM) The part comes with **T766** pre-applied to the base. In electronics, the TIM is crucial because it fills microscopic air gaps between the heat source (the chip) and the heat sink, significantly increasing heat transfer efficiency. #### B. Push-Pin Attachment Mechanism Instead of using adhesive tape or epoxy, which can be permanent or fail under high heat, this model uses **Brass Push-Pins**. - **Reliability:** Provides consistent pressure (force) on the component for optimal thermal contact. - **Serviceability:** Allows the heat sink to be removed and reattached during PCB repair or upgrades. #### C. Fin Design (Cross-Cut) The "72" in the series often denotes the fin configuration. This heat sink uses a **straight-fin or cross-cut design** which allows for multi-directional airflow. This is critical in cramped electronic enclosures where the fan direction might not be perfectly aligned with the heat sink. --- ### 3. Application Use Cases This component is typically found in the following electronic environments: 1. **Network Switches/Routers:** Cooling high-speed processing chips. 2. **Embedded Systems:** Used on SoCs (System on Chips) that generate significant heat in a small form factor. 3. **Power Supplies:** Managing thermal loads on voltage regulators or MOSFETs. --- ### 4. Comparison of Thermal Resistance | Airflow Velocity (LFM) | Thermal Resistance (°C/W) | | :--- | :--- | | 100 (Natural/Low) | 5.11 | | 300 (Medium) | 2.05 | | 500 (High) | 1.61 | *Note: Lower °C/W values indicate better cooling performance.*
