The **ATS-53290R-C2-R0** is a high-performance heat sink manufactured by **Advanced Thermal Solutions (ATS)**. It is part of the "maxiFLOW™" series, designed specifically for cooling electronic components like CPUs, GPUs, FPGAs, and ASICs. ### 1. Technical Specifications Below is a breakdown of the primary physical and thermal characteristics of this part: | Characteristic | Specification | | :--- | :--- | | **Material** | Aluminum (Anodized Blue) | | **Dimensions** | 29.00mm x 29.00mm x 24.50mm | | **Attachment Method** | maxiGRIP™ (Frame Clip) | | **Fin Style** | Spread Fin (maxiFLOW™ Design) | | **Thermal Resistance** | 2.50 °C/W (at 200 LFM) | | **Thermal Interface Material** | T766 (Pre-applied) | --- ### 2. Key Electronic & Mechanical Features #### A. The maxiFLOW™ Fin Design Unlike traditional straight-fin heat sinks, the ATS-53290R-C2-R0 uses a **tapered fin design**. This geometry is engineered to maximize surface area for air contact while minimizing pressure drop. In electronic enclosures where airflow may be limited, this design increases the efficiency of heat dissipation (convection). #### B. The maxiGRIP™ Attachment System This is one of the most critical electronic "parts" of the assembly. It consists of a **plastic frame clip** and a **stainless steel spring clip**: * **No Holes Required:** It attaches directly to the component/PCB without needing to drill holes in the board. * **Constant Pressure:** The spring clip ensures a consistent, high-pressure contact between the heat sink and the electronic chip, which is vital for thermal transfer. * **Protection:** The frame clip provides a "mechanical stop" that prevents the heat sink from shifting or damaging the delicate solder balls (BGA) of the chip during vibration or shipping. #### C. Thermal Interface Material (TIM) The part comes with **T766** pre-applied to the base. This is a phase-change material or high-performance pad that fills the microscopic air gaps between the electronic chip's surface and the aluminum base of the heat sink, significantly reducing thermal impedance. --- ### 3. Application Use Cases This specific heat sink is typically used for components with a **29mm x 29mm** footprint. Common applications include: * **Networking Equipment:** Routers and switches where high-speed processors generate significant heat. * **Embedded Systems:** Industrial PCs where space is limited but thermal loads are high. * **Telecommunications:** Cooling of signal processing units.
