Key Technical Specifications | Feature | Specification | | :--- | :--- | | **Part Number** | ATS-20F-51-C2-R0 | | **Material** | Aluminum (AL-6063) | | **Finish** | Blue Anodized | | **Attachment Method** | pushPIN™ (Spring-loaded) | | **Thermal Resistance** | 6.69°C/W (Unducted Flow @ 200 LFM) | | **Dimensions (L x W)** | 35.00 mm x 35.00 mm | | **Height (Fin)** | 30.00 mm | | **Pitch** | Fine Pitch | --- ### 2. Design and Component Breakdown #### A. Fin Geometry and Material * **Fine Pitch Design:** The heat sink features a high density of fins. This increases the total surface area available for heat dissipation, making it highly effective for forced air cooling (fans). * **Aluminum 6063:** This specific alloy is used because it offers an excellent balance between thermal conductivity, structural strength, and corrosion resistance. #### B. The pushPIN™ Attachment System One of the defining "electronic parts" of this assembly is the mounting hardware: * **Push Pins:** These are pre-assembled with the heat sink to ensure easy and consistent installation onto the Printed Circuit Board (PCB). * **Compression Springs:** They provide a precise "Force" (Pressure) to ensure maximum contact between the heat sink base and the electronic component (CPU/GPU/FPGA), minimizing thermal interface resistance. #### C. Thermal Interface Material (TIM) * The part usually comes with a pre-applied **Phase Change Material** or thermal tape. This eliminates the microscopic air gaps between the heat sink and the chip, ensuring efficient heat transfer. --- ### 3.
