### Technical Overview: ATS-20B-25-C2-R0 The **ATS-20B-25-C2-R0** is a high-performance electronic thermal management component, specifically a **Heat Sink** from Advanced Thermal Solutions (ATS). It is part of the "maxiFLOW™" series, designed for high-efficiency cooling of surface-mount components like CPUs, GPUs, and FPGAs. --- ### 1. Technical Specifications The part number encodes specific structural and thermal characteristics. Here is the breakdown: | Specification | Value / Detail | | :--- | :--- | | **Manufacturer** | Advanced Thermal Solutions (ATS) | | **Type** | Pin Fin Heat Sink (maxiFLOW™) | | **Material** | Aluminum (Black Anodized) | | **Dimensions** | 25mm x 25mm (Base) | | **Height** | 20mm | | **Attachment Method** | pushPIN™ (Spring-loaded) | | **Thermal Resistance** | ~5.16°C/W (at 200 LFM) | | **Interface Material** | T766 (Thermal Tape/Grease options) | --- ### 2. Key Components & Design Features #### A. The Fin Geometry The "maxiFLOW" design features a **flared fin structure**. Unlike traditional straight fins, these fins angle outwards to maximize the surface area and increase turbulence. This allows for better heat dissipation in environments with constrained airflow. #### B. The pushPIN™ Attachment This model uses the **pushPIN™** system, which consists of: * **Springs:** Ensure consistent pressure between the heat sink and the chip to minimize thermal resistance. * **Plastic/Brass Pins:** Inserted through pre-drilled holes in the PCB to lock the assembly in place. #### C. Thermal Interface Material (TIM) The **C2** designation in the part number usually indicates the type of thermal interface material applied to the base. * It ensures that microscopic air gaps between the heat sink and the electronic component are filled, facilitating efficient heat transfer. --- ### 3. Application Use Cases This specific heat sink is typically used in the following electronic assemblies: 1. **Telecommunications:** High-speed routers and switches where air velocity is high. 2. **Embedded Systems:** Industrial PCs where vertical space is limited to 20mm. 3. **Power Electronics:** Cooling MOSFETs or voltage regulators that generate localized heat spots. --- ### 4. Thermal Performance Data *Measured in °C/W (Lower is better)* | Airflow Velocity (LFM) | Thermal Resistance (°C/W) | | :--- | :--- | | 200 (1.0 m/s) | 5.16 | | 400 (2.0 m/s) | 3.20 | | 600 (3.0 m/s) | 2.50 | ---
