The **ATS-20F-27-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 PCB-mounted components. --- ### 1. Technical Specifications The following table outlines the key physical and thermal characteristics of this specific part number: | Attribute | Specification | | :--- | :--- | | **Manufacturer** | Advanced Thermal Solutions Inc. | | **Part Number** | ATS-20F-27-C2-R0 | | **Heat Sink Type** | XCUT (Cross-Cut) | | **Material** | Aluminum | | **Finish** | Blue Anodized | | **Dimensions (L x W x H)** | 40mm x 40mm x 12.7mm | | **Attachment Method** | Push Pin (Plastic) | | **Thermal Interface Material (TIM)** | T766 (Pre-applied) | --- ### 2. Design and Component Breakdown #### A. The Fin Geometry (XCUT) The "XCUT" design features a cross-cut pattern that creates a grid of square or rectangular pins. This design is highly effective for: * **Omnidirectional Airflow:** Unlike straight-fin heat sinks that require air to flow in one specific direction, cross-cut fins allow air to enter from any angle. * **Increased Surface Area:** The pattern increases the area available for heat dissipation relative to the footprint. #### B. The Push Pin Attachment The **-C2-R0** designation typically refers to the attachment kit. * **Push Pins:** These are spring-loaded plastic or brass pins that snap into pre-drilled holes on the PCB. * **Springs:** The pins use springs to provide constant downward pressure, ensuring the heat sink stays flush against the chip even during mechanical vibration. #### C. Thermal Interface Material (TIM) This part comes with **T766** pre-applied to the base. * The TIM fills microscopic air gaps between the component (CPU/GPU/FPGA) and the aluminum base of the heat sink. * Pre-application ensures a uniform layer, reducing the risk of overheating due to improper manual paste application. --- ### 3. Thermal Performance Indicators Thermal resistance is the critical metric for this part, measured in degrees Celsius per Watt (°C/W). * **Unducted Flow (Low Airflow):** High thermal resistance (e.g., ~12.0 °C/W). * **Ducted/High Airflow (200-500 LFM):** Resistance drops significantly (e.g., ~2.5 - 4.0 °C/W), allowing for much more aggressive cooling. --- ### 4. Typical Applications * **Network Equipment:** Routers, switches, and base stations. * **Embedded Systems:** Industrial PCs and controllers. * **Power Supplies:** Cooling high-wattage MOSFETs or voltage regulators.
