Key Technical Specifications | Parameter | Specification | | :--- | :--- | | **Manufacturer** | Advanced Thermal Solutions (ATS) | | **Series** | pushPIN™ | | **Material** | Aluminum | | **Finish** | Blue Anodized | | **Attachment Method** | Push-Pin | | **Thermal Resistance (Flowing)** | 18.63 °C/W @ 100 LFM | | **Thermal Resistance (Static)** | 25.50 °C/W @ 0 LFM | | **Dimensions (L x W x H)** | 40.00mm x 40.00mm x 10.00mm | --- ### 2. Core Components and Design Features #### A. The Fin Structure (C3 Configuration) * **Design:** The "C3" designation typically refers to a **Straight Fin** or specific density pattern optimized for airflow. * **Airflow Direction:** Designed for longitudinal airflow. The fins increase the surface area to facilitate heat transfer from the component to the surrounding air. #### B. The pushPIN™ Attachment System Unlike adhesive-based sinks, this part uses a mechanical **Push-Pin** system: * **Reliability:** Provides consistent pressure on the component to ensure optimal thermal interface material (TIM) performance. * **Flexibility:** Includes a pre-drilled hole pattern for easy installation onto a PCB. * **Springs:** Usually paired with stainless steel or brass springs to maintain tension without damaging the board. #### C. Material and Coating * **Aluminum 6063:** Chosen for its excellent thermal conductivity and lightweight properties. * **Blue Anodized Finish:** This is not just for aesthetics; the anodized layer provides corrosion resistance and slightly improves radiant heat emission. --- ### 3. Thermal Performance Metrics The efficiency of this heat sink is measured by its **Thermal Resistance**. Lower values indicate better heat dissipation. | Airflow Velocity (LFM) | Thermal Resistance (°C/W) | | :--- | :--- | | 100 (0.5 m/s) | 18.63 | | 200 (1.0 m/s) | 7.15 | | 300 (1.5 m/s) | 4.86 | | 400 (2.0 m/s) | 3.77 | --- ### 4. Applications * **BGA Cooling:** Ideal for chipsets and integrated circuits. * **Embedded Systems:** Used in industrial PCs where space is limited (10mm height). * **Networking Gear:** Cooling for routers and switches where constant airflow is present. ---
