The **ATS-16D-20-C2-R0** is a high-performance electronic thermal management component, specifically a **Heat Sink** manufactured by *Advanced Thermal Solutions, Inc. (ATS)*. It is designed to dissipate heat from surface-mount components like BGA (Ball Grid Array) chips. --- ## 1. Technical Specifications The part number follows a specific nomenclature that defines its physical and thermal characteristics. | Feature | Specification | | :--- | :--- | | **Material** | Aluminum (High thermal conductivity) | | **Finish** | Blue Anodized (Enhanced emissivity) | | **Dimensions** | 54.00mm x 54.00mm | | **Height** | 25.00mm | | **Attachment Type** | pushPIN™ (Spring-loaded) | | **Thermal Resistance** | 7.14°C/W (at 100 LFM) to 1.55°C/W (at 700 LFM) | | **Thermal Interface Material** | T766 (High-performance grease) | --- ## 2. Key Electronic Features ### A. pushPIN™ Mounting System Unlike adhesive-based heat sinks, this model uses a **pushPIN™** attachment mechanism. This is critical for electronics because: * **Reliability:** It provides a consistent downward force (pressure) on the chip, ensuring a stable thermal connection. * **Reusability:** It can be removed and reattached during hardware debugging or maintenance. * **Vibration Resistance:** The spring-loaded pins prevent the heat sink from shifting during mechanical shock or vibration. ### B. Fin Geometry (Cross-Cut) The "D" in the part number indicates a specific fin design. These heat sinks typically feature a **high-aspect-ratio fin design** or cross-cut patterns that allow for: * Multi-directional airflow (improving performance in dense PCB layouts). * Maximum surface area for heat exchange without significantly increasing the footprint. ### C. Thermal Interface Material (TIM) The part comes pre-applied with **T766 thermal grease**. In electronics, the TIM is vital because it fills microscopic air gaps between the semiconductor die and the aluminum heat sink, drastically reducing thermal impedance. --- ## 3. Typical Applications This component is used to cool integrated circuits (ICs) that generate significant heat, such as: * **FPGA & ASICs:** Used in telecommunications and data centers. * **Processors:** Embedded CPUs or high-end microcontrollers. * **Video Processing Units:** Chips used in high-definition imaging systems. --- ## 4. Performance Data (Airflow vs. Thermal Resistance) Thermal performance in electronics is measured by how much the temperature rises per Watt of power. | Airflow Velocity (LFM) | Thermal Resistance (°C/W) | | :--- | :--- | | 100 (0.5 m/s) | 7.14 | | 300 (1.5 m/s) | 2.62 | | 500 (2.5 m/s) | 1.86 | | 700 (3.5 m/s) | 1.55 |
