The **ATS-18B-56-C3-R0** is a high-performance electronic thermal management component, specifically a **Heat Sink** manufactured by Advanced Thermal Solutions (ATS). It is designed to dissipate heat from electronic components like CPUs, GPUs, or high-power transistors. ### 1. Technical Specifications The following table outlines the physical and thermal properties of this specific model: | Parameter | Specification | | :--- | :--- | | **Manufacturer** | Advanced Thermal Solutions (ATS) | | **Series** | pushPIN™ | | **Material** | Aluminum | | **Finish** | Blue Anodized | | **Dimensions (L x W)** | 40mm x 40mm | | **Height** | 10mm | | **Attachment Type** | Push-Pin (Plastic) | | **Thermal Resistance** | 17.86°C/W (Unducted Flow @ 100 LFM) | | **Flow Direction** | Vertical (Cross-Cut) | --- ### 2. Design and Construction Features * **Finned Structure:** The "pushPIN™" design features a high-density fin array which maximizes surface area for convective cooling. The cross-cut pattern allows for multi-directional airflow, making it versatile for different system layouts. * **Material Selection:** Aluminum is used for its high thermal conductivity and lightweight properties, ensuring efficient heat transfer from the base to the fins. * **Thermal Interface Material (TIM):** This part typically comes pre-applied with **T412** thermal tape or high-performance grease to ensure minimal thermal resistance between the heat source and the sink. --- ### 3. Mounting Mechanism (Push-Pin) The "C3" in the part number indicates the specific hardware used for mounting: 1. **Spring-Loaded Pins:** These provide a precise "engagement force" to keep the heat sink firmly against the chip, preventing air gaps. 2. **Simplified Installation:** Push-pins snap into pre-drilled holes (usually 3mm diameter) on the PCB, eliminating the need for specialized tools or adhesive curing times. --- ### 4.
