The **ATS-18D-20-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 part number encodes specific physical and thermal characteristics: | Attribute | Specification | | :--- | :--- | | **Manufacturer** | Advanced Thermal Solutions, Inc. (ATS) | | **Heat Sink Type** | Push-pin style (Straight Fin) | | **Material** | Aluminum | | **Finish** | Blue Anodized | | **Thermal Resistance** | 7.14°C/W (Unducted Flow @ 200 LFM) | | **Attachment Method** | Plastic Push-Pin & Compression Spring | | **Dimensions (L x W x H)** | 45mm x 45mm x 25mm | | **Thermal Interface Material** | T766 (Pre-applied phase change material) | --- ### 2. Breakdown of the Part Number Understanding the nomenclature helps in identifying the component's utility: * **ATS**: The manufacturer prefix. * **18D**: Refers to the specific series and mounting hole pattern. * **20**: The height of the heat sink (25mm in this specific sub-series context). * **C2**: Indicates the material/finish (Aluminum with Blue Anodization). * **R0**: Refers to the version or revision (Standard performance). --- ### 3. Key Electronic Components While the heat sink itself is mechanical, it interacts with electronics via three critical components: #### A. The Fin Array (Thermal Dissipation) The straight-fin design is optimized for **forced air cooling**. In electronic systems, as air moves across the aluminum fins, heat is transferred from the metal to the atmosphere. The 45x45mm footprint is standard for medium-sized BGAs (Ball Grid Arrays). #### B. The Thermal Interface Material (TIM) The "T766" mentioned in the specs is a thermal pad or paste pre-applied to the base. This fills microscopic air gaps between the electronic chip (heat source) and the heat sink base, ensuring maximum heat transfer efficiency. #### C. The Attachment System (Push-Pins) Unlike adhesive-based heat sinks, this uses **brass or plastic push-pins** with springs. This provides: * **Constant Pressure:** Ensures the TIM is compressed correctly against the chip. * **Vibration Resistance:** Securely holds the part in place during shipping or operation. * **Reusability:** Can be removed and reinstalled without damaging the PCB. --- ### 4. Typical Applications * **Telecommunications:** Cooling network switches and routers. * **Embedded Systems:** High-speed processors in industrial controllers. * **Power Electronics:** Dissipating heat from large voltage regulators.
