The **ATS-1139-C1-R0** is a specialized high-performance heat sink assembly manufactured by **Advanced Thermal Solutions (ATS)**. It is part of their "SuperGrip" series, designed for cooling high-heat-generating electronic components, specifically Ball Grid Array (BGA) packages. ### 1. Key Technical Specifications | Parameter | Specification | | :--- | :--- | | **Manufacturer** | Advanced Thermal Solutions (ATS) | | **Part Number** | ATS-1139-C1-R0 | | **Heat Sink Material** | Aluminum (Black Anodized) | | **Attachment Method** | SuperGrip (Frame Clip and Spring Clip) | | **Thermal Resistance** | Variable (Typically ~4-7 °C/W depending on airflow) | | **Dimensions** | 40mm x 40mm x 9.5mm | --- ### 2. Physical Components & Electronic Integration The ATS-1139-C1-R0 is not an active electronic component (like a chip) but rather a **mechanical thermal management system**. It consists of several integral parts that interact with the PCB: #### A. The Heat Sink (Fin Array) * **Design:** Usually features a **straight-fin** or **cross-cut** design to maximize surface area. * **Material:** Made from high-grade aluminum. The **Black Anodized** finish increases emissivity, allowing for better heat radiation. #### B. The SuperGrip™ Attachment System This is the most critical part for electronic assembly. It uses a two-part system to secure the heat sink to the chip without requiring holes in the PCB: 1. **Plastic Frame Clip:** A high-temperature plastic frame that snaps around the perimeter of the BGA component. 2. **Metal Spring Clip:** A "horseshoe" shaped spring that applies constant downward pressure on the heat sink, ensuring a tight thermal bond with the component. #### C. Thermal Interface Material (TIM) The "R0" at the end of the part number often indicates a specific revision or packaging. These units typically come with a **Phase Change Material (PCM)** or a thermal pad pre-applied to the bottom surface to fill microscopic air gaps between the chip and the metal. --- ### 3. Application Use Cases This part is used in electronics where reliability and heat dissipation are critical but board space is limited: * **Networking Equipment:** High-speed routers, switches, and gateways. * **Telecommunications:** Base stations and signal processing units. * **Embedded Systems:** Industrial PCs and FPGA-based controllers. * **Video Processing:** High-definition encoders and GPUs. --- ### 4. Advantages for PCB Design * **No PCB Holes:** Unlike traditional push-pin heat sinks, this does not require holes, allowing designers to route traces directly under the component. * **High Pressure:** The spring clip ensures consistent pressure, which is vital for preventing the chip from overheating during thermal expansion. * **Removability:** The clip system allows the heat sink to be removed for chip rework or maintenance without damaging the PCB.
