The **ATS-18A-37-C2-R0** is a high-performance electronic thermal management component, specifically a **Heat Sink** manufactured by Advanced Thermal Solutions (ATS). It is part of the "push pin" series designed for cooling surface-mount components like BGA (Ball Grid Array) chips. --- ### 1. Technical Specifications The part number encodes specific physical and thermal characteristics: | Feature | Specification | | :--- | :--- | | **Material** | Aluminum | | **Finish** | Blue Anodized | | **Attachment Method** | Push-Pin (Brass) | | **Spring Type** | Compression Spring | | **Thermal Resistance** | 9.12°C/W (at 200 LFM) | | **Base Dimensions** | 36.83mm x 36.83mm | | **Height** | 22.86mm | | **Thermal Interface Material (TIM)** | T766 (Pre-applied) | --- ### 2. Breakdown of the Part Number Advanced Thermal Solutions uses a structured naming convention: * **ATS**: Manufacturer (Advanced Thermal Solutions). * **18A**: Indicates the specific series and mounting hole pattern. * **37**: Refers to the physical size (approx. 37mm). * **C2**: Refers to the material and thermal performance grade. * **R0**: Indicates the version or revision (RoHS compliant). --- ### 3. Key Electronic Components Though it is a mechanical part, it interacts with electronics in the following ways: #### A. The Heat Sink Body The "cross-cut" fin design allows for multi-directional airflow. This is critical in electronics enclosures where the direction of the cooling fan's exhaust might not be perfectly aligned with the chip. #### B. Push-Pin Mounting System Instead of using adhesive tape (which can fail under high heat), this part uses **brass push-pins** with steel springs. This provides: * **Uniform Pressure:** Ensures the heat sink stays flat against the chip for maximum heat transfer. * **Reliability:** Resistant to vibration and mechanical shock. #### C. Thermal Interface Material (TIM) The base is pre-coated with **T766 phase-change material**. When the electronic component heats up, this material softens to fill microscopic air gaps between the chip surface and the aluminum base, significantly lowering thermal resistance. --- ### 4. Typical Applications This specific part size is commonly used for cooling: * CPUs and GPUs in embedded systems. * FPGAs (Field Programmable Gate Arrays). * High-speed networking ASICs. * Power supplies and industrial controllers.
