The **ATS-20D-63-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" attachment series designed for cooling electronic components like CPUs, GPUs, or high-power semiconductors. --- ### 1. Technical Specifications The part number encodes specific physical and thermal characteristics: | Feature | Specification | | :--- | :--- | | **Material** | Aluminum (Anodized Blue) | | **Fin Type** | Straight Fin | | **Dimensions (L x W x H)** | 40mm x 40mm x 20mm | | **Attachment Method** | Push Pin (Brass) with Compression Spring | | **Thermal Resistance** | ~2.85°C/W (at 200 LFM) | | **Thermal Interface Material (TIM)** | T766 (High Performance Phase Change) | --- ### 2. Key Electronic Components Breakdown #### A. The Heat Sink Body The body is constructed from extruded aluminum. Its primary role is to increase the surface area of a heat-generating component (like an Integrated Circuit), allowing for more efficient heat dissipation into the surrounding air. #### B. Push Pin & Spring Mechanism Unlike adhesive-based heat sinks, the "20D" series uses a mechanical attachment: * **Brass Push Pins:** Ensure a secure, permanent fit to the PCB. * **Compression Springs:** These apply a precise amount of "downward pressure" (load) to the component, ensuring the thermal interface material is squeezed to its optimal thickness for maximum heat transfer. #### C. Thermal Interface Material (TIM) The **-R0** suffix indicates that it comes pre-applied with **T766**. This is a phase-change material that melts when the component gets hot, filling microscopic air gaps between the chip and the heat sink to reduce thermal resistance. --- ### 3. Thermal Performance Profile The effectiveness of this part depends on the airflow (LFM - Linear Feet per Minute) within the electronic enclosure: | Airflow (LFM) | Thermal Resistance (°C/W) | | :--- | :--- | | 200 (Low flow) | 2.85 | | 400 (Moderate) | 1.80 | | 600 (High flow) | 1.45 | --- ### 4. Typical Applications * **Networking Gear:** Switches and routers where high-speed processors generate significant heat. * **Embedded Systems:** Industrial PCs where mechanical stability (push pins) is preferred over adhesives due to vibration. * **Power Supplies:** Cooling MOSFETs or voltage regulators.
