The **ATS-12B-65-C2-R0** is a high-performance electronic thermal management component, specifically an **Advanced Thermal Solutions (ATS) Push-Pin Heat Sink**. It is designed to dissipate heat from electronic integrated circuits (ICs) like CPUs, GPUs, or FPGAs. --- ### 1. Technical Specifications The following table breaks down the critical physical and thermal properties of this specific part number: | Property | Specification | | :--- | :--- | | **Manufacturer** | Advanced Thermal Solutions (ATS) | | **Material** | Aluminum (AL6063) | | **Finish** | Blue Anodized | | **Attachment Method** | Push-Pin (Brass) / Compression Spring | | **Dimensions (L x W)** | 45mm x 45mm | | **Height** | 25mm | | **Thermal Resistance** | ~1.3°C/W (at 200 LFM) | | **Thermal Interface Material (TIM)** | T766 (Pre-applied) | --- ### 2. Part Number Breakdown The part number is a coded string representing the specific configuration of the cooling solution: - **ATS-12B**: Refers to the "maxiFLOW™" series, known for its high-density fin structure and low pressure drop. - **65**: Represents the specific internal dimensions and fin pattern. - **C2**: Indicates the color/finish (Blue Anodized) and the thermal performance class. - **R0**: Refers to the revision code or specific packaging/material compliance (RoHS). --- ### 3. Key Electronic Functions While the heat sink itself is passive (it does not require electricity to run), it is essential for the reliability of electronic systems: * **Heat Dissipation:** It increases the surface area of the component it is mounted on, allowing air (convection) to carry away heat generated by electrical resistance. * **Thermal Protection:** By maintaining the junction temperature ($T_j$) below the manufacturer's limit, it prevents **thermal throttling** (performance slowdown) and permanent hardware failure. * **Mechanical Stability:** The "Push-Pin" attachment ensures a precise and consistent pressure across the chip, which is vital for the efficiency of the Thermal Interface Material (TIM). --- ### 4. Implementation Details * **Mounting:** Requires pre-drilled holes in the PCB. The brass push-pins use a spring-loaded mechanism to snap into place. * **Airflow Direction:** This model is designed for **longitudinal airflow**. The fins are oriented to maximize cooling when air moves parallel to the fin length. * **Compatibility:** Best suited for high-power BGA (Ball Grid Array) packages where standard adhesive-based heat sinks might fail due to weight or heat. ---
