The **ATS-01B-77-C3-R0** is a high-performance heat sink manufactured by **Advanced Thermal Solutions (ATS)**. It is part of the "blue ICE" series, specifically designed for thermal management of electronic components like CPUs, GPUs, and other high-power ICs. --- ### 1. Key Technical Specifications | Feature | Specification | | :--- | :--- | | **Material** | Aluminum | | **Finish** | Blue Anodized | | **Attachment Method** | Push-Pin (with springs) | | **Thermal Resistance** | 9.58°C/W (at 200 LFM) | | **Dimensions (L x W x H)** | 25.00mm x 25.00mm x 20.00mm | | **Fin Style** | Straight (Extruded) | --- ### 2. Electronic Component Breakdown While the heat sink itself is mechanical, its "electronic parts" refer to the mounting interface and the specific design choices for heat dissipation: #### A. The Push-Pin Mechanism Unlike adhesive heat sinks, this model uses a **brass push-pin with a stainless steel spring**. * **Purpose:** Provides a consistent, high-pressure connection to the PCB. * **Reliability:** Ensures the heat sink stays attached during vibration or thermal cycling. #### B. Thermal Interface Material (TIM) The "C3" in the part number indicates the presence of a pre-applied thermal material. * **Material:** Often **Phase Change Material (PCM)** or high-performance grease. * **Function:** Fills microscopic air gaps between the electronic chip (die) and the aluminum base to lower contact resistance. #### C. Fin Geometry The straight-fin design is optimized for **forced air cooling**. In an electronic enclosure, this part is intended to be placed in the path of a cooling fan. The spacing is calculated to minimize pressure drop while maximizing surface area. --- ### 3. Common Applications This specific footprint (25mm x 25mm) is typically used for cooling the following electronic components: 1. **BGA Packages:** Large Ball Grid Array chips. 2. **ASICs:** Application-Specific Integrated Circuits. 3. **Voltage Regulators:** High-current power management modules. 4. **Network Processors:** Found in routers and switches. ---
