The **ATS-15B-129-C2-R0** is a high-performance electronic thermal management component, specifically a **Heat Sink** manufactured by Advanced Thermal Solutions (ATS). It belongs to the **maxiFLOW™** series, designed to provide high cooling efficiency in constrained airflows. --- ### 1. Technical Specifications Below are the primary physical and thermal characteristics of the part: | Feature | Specification | | :--- | :--- | | **Material** | Aluminum (Blue Anodized) | | **Dimensions** | 54.00mm x 54.00mm | | **Height** | 10.00mm | | **Thermal Resistance** | 8.68°C/W (at 200 LFM) | | **Attachment Method** | pushPIN™ | | **Spring Type** | Brass (Nickel Plated) | | **Thermal Interface (TIM)** | T766 (Pre-applied) | --- ### 2. Key Electronic Components & Design The "electronic" nature of this part relates to its thermal architecture and mounting system: #### A. The maxiFLOW™ Fin Design Unlike standard extruded heat sinks, the maxiFLOW™ design features a flared fin structure. This increases the surface area and encourages turbulent airflow, which significantly lowers the thermal resistance between the electronic component (like a CPU, FPGA, or GPU) and the ambient air. #### B. pushPIN™ Attachment System The part uses a specialized mounting system that ensures consistent pressure: * **Compression Springs:** Provide the exact "clamping force" required to maximize contact with the chip without damaging the PCB. * **Plastic/Brass Pins:** Secure the unit through pre-drilled holes in the motherboard. #### C. Thermal Interface Material (T766) This heat sink comes pre-applied with **T766**, a high-performance phase-change material. In electronics, this acts as the bridge that fills microscopic air gaps between the heat sink and the semiconductor, ensuring efficient heat transfer. --- ### 3.
