The **ATS-50375P-C1-R0** is a high-performance heat sink manufactured by **Advanced Thermal Solutions (ATS)**. It is part of the "superGRIP" series, designed specifically for high-density electronic cooling applications such as BGA (Ball Grid Array) components. --- ### 1. Technical Specifications The following table outlines the physical and thermal properties of the part: | Feature | Specification | | :--- | :--- | | **Manufacturer** | Advanced Thermal Solutions (ATS) | | **Heat Sink Type** | maxiFLOW™ Cross-Cut | | **Attachment Method** | superGRIP™ (Clip-on) | | **Dimensions (L x W x H)** | 37.5mm x 37.5mm x 22.5mm | | **Material** | Aluminum (Black Anodized) | | **Thermal Resistance** | 1.9 °C/W @ 200 LFM | | **Thermal Interface Material (TIM)** | Saint-Gobain C675 | --- ### 2. Key Design Components #### A. maxiFLOW™ Fin Geometry The fins are designed with a tapered, spread-fin geometry. This increases the surface area significantly compared to standard square-fin designs, which allows for better airflow through the sink and lower thermal resistance. #### B. superGRIP™ Attachment Instead of using messy adhesives or drilling holes into the PCB for screws, this part uses a **plastic frame clip** and a **stainless steel spring clip**: * **The Frame:** Attaches to the base of the BGA component. * **The Spring:** Snaps into the frame to apply steady downward pressure, ensuring optimal contact between the heat sink and the chip. #### C. Thermal Interface Material (TIM) The unit comes pre-applied with **Saint-Gobain C675** phase-change material. This ensures that the microscopic gaps between the chip surface and the heat sink base are filled, reducing the "contact resistance" that often hinders cooling. --- ### 3. Electronic Application Use-Cases The ATS-50375P-C1-R0 is typically used in the following electronic environments: * **Networking Equipment:** Switches, routers, and high-speed hubs. * **Embedded Systems:** Industrial PC boards and IoT gateways. * **Telecommunications:** Base stations and signal processing units. * **Power Electronics:** Cooling for high-performance ASICs, FPGAs, and processors. --- ### 4. Installation Overview The assembly process is non-intrusive to the PCB: 1. **Placement:** The plastic frame is placed around the BGA component. 2. **Seating:** The heat sink (with pre-applied TIM) is placed inside the frame. 3. **Securing:** The metal spring clip is snapped over the assembly, providing the necessary clamping force.
