The part number **ATS-20D-94-C2-R0** refers to a high-performance **Heatsink** manufactured by **Advanced Thermal Solutions (ATS)**. It is part of their *push-pin* attachment line, designed specifically for cooling electronic components like CPUs, GPUs, or high-power ASICs. --- ### 1. Technical Specifications Below are the primary physical and thermal characteristics of this component: | Feature | Specification | | :--- | :--- | | **Material** | Aluminum (High Thermal Conductivity) | | **Finish** | Blue Anodized | | **Attachment Method** | Push-Pin (Plastic) with Compression Spring | | **Dimensions** | 40mm x 40mm x 25mm | | **Fin Type** | Straight Fin | | **Thermal Resistance** | Approx. 4.46 °C/W (at 200 LFM) | | **RoHS Status** | Compliant (R0 designation) | --- ### 2. Design and Component Breakdown #### A. Fin Profile (The Cooling Surface) The "94" series typically features a straight-fin design. These fins provide a large surface area for heat dissipation. Because they are straight, they are best suited for **forced-air cooling** (environments with fans) rather than passive cooling. #### B. Attachment Mechanism (Push-Pins & Springs) The "20D" designation involves the mounting hardware: * **Push-Pins:** These allow for easy installation into pre-drilled holes on the PCB. * **Compression Springs:** These ensure a consistent "clamping force" (pressure) between the heatsink base and the chip, which is critical for efficient heat transfer. #### C. Interface Material (Thermal Pad) This specific part often comes with a **Phase Change Material (PCM)** or a high-performance thermal interface pre-applied to the base. This fills the microscopic air gaps between the component and the heatsink. --- ### 3.
