The **ATS-53190R-C1-R0** is a high-performance heat sink component manufactured by **Advanced Thermal Solutions (ATS)**. It is part of their "maxiFLOW™" product line, designed specifically for cooling high-heat-generating electronic components like BGAs (Ball Grid Arrays). ### 1. Key Technical Specifications The following table summarizes the physical and thermal properties of this specific model: | Parameter | Specification | | :--- | :--- | | **Dimensions** | 19.0mm x 19.0mm x 14.5mm | | **Material** | Aluminum (Black Anodized) | | **Attachment Method** | maxiGRIP™ (Frame Clip) | | **Fin Style** | maxiFLOW™ (Spread Fin) | | **Thermal Resistance** | 9.0 °C/W (at 200 LFM) | | **RoHS Status** | Compliant | --- ### 2. Functional Electronic Components While the heat sink itself is a passive mechanical part, its design includes several critical subsystems that interact with the electronic assembly: #### A. maxiFLOW™ Fin Geometry The "spread fin" design is engineered to maximize surface area for convective heat transfer. In electronic systems with limited airflow, this geometry reduces pressure drop and allows more air to pass through the fins, increasing cooling efficiency for high-density PCBs. #### B. maxiGRIP™ Attachment System This is the most critical "part" of the assembly. Instead of using thermal tape or permanent epoxy, it uses: * **Plastic Frame Clip:** Reaches around the electronic component. * **Stainless Steel Spring Clip:** Provides consistent downward pressure (300g per mm²) to ensure optimal contact between the die and the heat sink. #### C. Interface Material (TIM) The "R0" designation typically implies the inclusion of a **Thermal Interface Material**. This is a pre-applied phase-change material or thermal pad that fills microscopic air gaps between the semiconductor package and the aluminum base to reduce thermal impedance. --- ### 3. Application Use Cases This part is commonly found in the following electronic environments: * **Networking Hardware:** Switches, routers, and high-speed modems. * **Embedded Systems:** Industrial PCs and controllers where space is tight. * **Optical Modules:** SFP and QSFP cooling. ---
