Based on the part number provided, the **ATS-1141-C1-R0** is a high-performance heat sink component from **Advanced Thermal Solutions (ATS)**. It is part of their **maxiFLOW™** series, designed specifically for cooling electronic components like BGA (Ball Grid Array) packages. --- ## 1. Technical Specifications The following table highlights the core physical and thermal properties of this component: | Feature | Specification | | :--- | :--- | | **Material** | Aluminum (Black Anodized) | | **Attachment Method** | maxiGRIP™ (Frame Clip) | | **Dimensions (L x W)** | 40.0 mm x 40.0 mm | | **Height** | 9.5 mm | | **Thermal Resistance** | ~2.50 °C/W @ 200 LFM | | **Compliance** | RoHS and REACH Compliant | --- ## 2. Key Electronic & Mechanical Parts The assembly consists of three primary elements that work together to protect the electronic IC (Integrated Circuit): ### A. The Heat Sink (The "Body") The heat sink features a **flared fin geometry**. Unlike standard straight-fin heat sinks, these fins curve outward to maximize surface area and increase air turbulence. This is critical for high-density PCBs where airflow might be limited. ### B. maxiGRIP™ Attachment System This is the mechanical "interface" between the part and the chip. It consists of: * **Plastic Frame Clip:** A high-strength plastic frame that surrounds the component. * **Stainless Steel Spring Clip:** A "cobra" shaped clip that snaps over the heat sink and into the frame. * **Benefit:** This avoids the need to drill holes in the PCB, preventing mechanical stress on the solder joints. ### C. Thermal Interface Material (TIM) The "R0" suffix typically denotes that the part comes pre-applied with a thermal pad or phase-change material. This fills the microscopic air gaps between the electronic chip and the aluminum heat sink to ensure efficient heat transfer. --- ## 3. Application Use Cases This specific part is used to manage heat in the following electronic environments: * **Telecommunications:** Network switches and routers. * **Data Centers:** Cooling high-speed processors or ASICs. * **Embedded Systems:** Industrial PCs where vertical space is limited (due to the low 9.5mm profile). ---
