### Technical Overview of ATS-16F-81-C2-R0 The **ATS-16F-81-C2-R0** is a high-performance electronic thermal management component, specifically a **Heat Sink** manufactured by **Advanced Thermal Solutions (ATS)**. It is part of their "push pin" series designed for securing the cooling element directly to a Printed Circuit Board (PCB). --- ### 1. Key Technical Specifications | Parameter | Specification | | :--- | :--- | | **Manufacturer** | Advanced Thermal Solutions Inc. (ATS) | | **Part Series** | pushPIN™ Heat Sink Assembly | | **Base Material** | Aluminum | | **Finish** | Blue Anodized | | **Thermal Resistance** | 1.40°C/W (at 200 LFM) | | **Attachment Method** | Push-Pin (Brass) | | **Spring Type** | Stainless Steel (ATS-PPS-16) | | **Thermal Interface Material** | T766 (Pre-applied) | --- ### 2. Component Design & Geometry The part is designed for high-density electronic environments where airflow is directed. * **Fin Profile (Straight Fin):** This model uses a straight fin design. This is ideal for systems with clear, unidirectional airflow, as it offers the least resistance to the air path while maximizing surface area. * **Dimensions:** * **Length/Width:** 30.00 mm x 30.00 mm * **Height:** 20.00 mm (This provides a medium profile, balancing clearance and cooling capacity). * **Hole Pattern:** 35.00 mm (The distance between the mounting holes on the PCB). --- ### 3. Electronic Application & Performance The "C2" in the part number indicates the material grade and finish (typically aluminum with a blue anodized coating). The blue anodizing is not just aesthetic; it provides a protective oxide layer that increases surface emissivity and protects against corrosion. #### Thermal Performance Table (Airflow vs. Resistance) | Air Velocity (LFM) | 100 | 200 | 400 | 600 | | :--- | :--- | :--- | :--- | :--- | | **Thermal Resistance (°C/W)** | 3.88 | 2.40 | 1.58 | 1.28 | --- ### 4. Mounting Mechanism (Push-Pin) The **ATS-16F-81-C2-R0** utilizes a push-pin assembly. This is preferred in electronic manufacturing because: 1. **Uniform Pressure:** The stainless steel springs ensure a constant, calibrated force is applied to the chip, optimizing the Thermal Interface Material (TIM) performance. 2. **Ease of Assembly:** It eliminates the need for specialized tools or adhesives, reducing the risk of component damage during installation. 3. **Vibration Resistance:** The mechanical locking of the pins is more reliable than adhesive tapes in high-vibration environments (e.g., industrial or networking gear).
