The **ATS-18A-128-C2-R0** is a high-performance electronic thermal management component, specifically an **Advanced Thermal Solutions (ATS) push-pin heatsink**. This part is designed to dissipate heat from electronic integrated circuits (ICs), such as CPUs, GPUs, or FPGAs. --- ### 1. Technical Specifications Below are the primary physical and thermal characteristics of this component: | Feature | Specification | | :--- | :--- | | **Manufacturer** | Advanced Thermal Solutions Inc. (ATS) | | **Material** | Aluminum (Blue Anodized) | | **Dimensions** | 54.00mm x 54.00mm | | **Height** | 25.00mm | | **Attachment Type** | Push-Pin (Brass, 2-Pin) | | **Thermal Resistance** | 2.91°C/W @ 100 LFM (Airflow) | | **Fin Style** | Straight Fin | | **Thermal Interface** | T766 (Pre-applied Phase Change Material) | --- ### 2. Key Components & Materials To understand the electronic application of this part, it is essential to look at its structural makeup: * **Heatsink Body:** Made of high-grade aluminum. The **Blue Anodized** finish is not just for aesthetics; it provides surface protection and slightly improves radiation heat transfer. * **The Fin Array:** Uses a "Straight Fin" design. This is optimized for **forced air cooling** (environments with fans) rather than passive cooling, as the fins are spaced to allow high-velocity air to pass through and carry away heat. * **Push-Pin Attachment:** The "18A" series features a spring-loaded brass push-pin mechanism. This ensures consistent pressure against the electronic chip, which is critical for maximizing the efficiency of the thermal interface. * **Thermal Interface Material (TIM):** This specific model comes with **T766** pre-applied. This is a phase-change material that fills microscopic air gaps between the chip surface and the heatsink base once it reaches operating temperature. --- ### 3. Part Number Decoder The part number `ATS-18A-128-C2-R0` can be broken down to understand its configuration: * **ATS:** Manufacturer prefix (Advanced Thermal Solutions). * **18A:** Product series (Push-pin style heatsink). * **128:** Dimensional/Design code for this specific 54x54x25mm block. * **C2:** Refers to the material and finish (Aluminum, Blue Anodized). * **R0:** Revision code or packaging indicator. --- ### 4. Implementation Logic In an electronic circuit, the thermal resistance ($\theta$) is calculated using the following logic to ensure the component does not overheat: ```python # Simple calculation for Temperature Rise power_dissipation_watts = 15.0 # Heat generated by the IC thermal_resistance_cw = 2.91 # ATS-18A-128-C2-R0 rating @ 100 LFM # Temperature rise above ambient temp_rise = power_dissipation_watts * thermal_resistance_cw print(f"The IC temperature will rise {temp_rise}°C above the internal case temperature.") ```
