The **ATS-18A-30-C2-R0** is a high-performance electronic thermal management component, specifically a heat sink designed for cooling integrated circuits (ICs) and other electronic packages. It belongs to the **maxiFLOW™** series manufactured by **Advanced Thermal Solutions (ATS)**. --- ### 1. Key Technical Specifications | Feature | Specification | | :--- | :--- | | **Manufacturer** | Advanced Thermal Solutions, Inc. (ATS) | | **Part Number** | ATS-18A-30-C2-R0 | | **Thermal Resistance** | 5.31°C/W (Unducted @ 200 LFM) | | **Material** | Aluminum | | **Finish** | Blue Anodized | | **Attachment Method** | pushPIN™ (Spring-loaded) | | **Dimensions (L x W x H)** | 70mm x 70mm x 25mm | --- ### 2. Physical Design and Construction #### **The maxiFLOW™ Geometry** The "maxiFLOW" design features a spread fin structure. Unlike standard square fin heat sinks, these fins taper outwards. This design increases the surface area for heat dissipation and improves airflow efficiency, reducing the pressure drop across the component. #### **Attachment Mechanism: pushPIN™** The part uses a **pushPIN™** assembly system. This includes: * **Brass/Plastic Pins:** Used to secure the heat sink to the PCB through pre-drilled holes. * **Stainless Steel Springs:** Provide precise, consistent pressure (compression force) on the electronic component to ensure optimal thermal contact. #### **Thermal Interface Material (TIM)** The "R0" suffix usually indicates that the heat sink comes with a pre-applied **Phase Change Material (PCM)** or high-performance thermal pad on the base. This fills microscopic air gaps between the heat sink and the chip to maximize heat transfer. --- ### 3.
