The **ATS-02A-40-C2-R0** is a high-performance electronic thermal management component, specifically a **Heatsink** manufactured by Advanced Thermal Solutions (ATS). It belongs to the "push pin" attachment series, designed to cool integrated circuits and other surface-mount components. --- ### 1. Technical Specifications Below are the primary physical and thermal characteristics of this part: | Parameter | Specification | | :--- | :--- | | **Material** | Aluminum | | **Finish** | Blue Anodized | | **Attachment Method** | Push-Pin (Plastic) | | **Dimension (L x W)** | 40.00mm x 40.00mm | | **Height** | 25.00mm | | **Thermal Resistance** | 14.56°C/W (at 100 LFM) | | **Flow Orientation** | Vertical or Horizontal (Omnidirectional) | --- ### 2. Key Electronic Components & Design This part is not an "active" electronic component (like a transistor) but an "essential passive" mechanical part designed for electronic systems. #### A. Fin Design (XC Series) The "XC" or cross-cut design features a pattern of square or rectangular pins/fins. This design is highly effective for: * **Omnidirectional Airflow:** It can receive cooling air from any direction, unlike straight-fin heatsinks that require the air to move parallel to the fins. * **Turbulence Generation:** The pin structure breaks up the boundary layer of air, increasing heat transfer efficiency. #### B. The Interface Material (TIM) The part usually comes pre-applied with **thermal interface material (TIM)**. In the case of the "C2" suffix, this typically refers to a high-performance thermal pad or grease that fills the microscopic air gaps between the heatsink base and the electronic chip (e.g., BGA, CPU, or FPGA). #### C. Push-Pin Attachment Mechanism Instead of using adhesive tape (which can fail under heat) or screws (which require holes in the PCB), this part uses: * **Plastic Push-Pins:** These provide a consistent "clamping force" on the electronic component. * **Compression Springs:** These ensure that even as the board expands or vibrates, the heatsink maintains a tight thermal connection with the chip. --- ### 3. Common Applications This heatsink is typically found cooling the following electronic parts: 1. **Processors (CPUs/GPUs):** Low-to-medium power embedded processors. 2. **FPGAs/ASICs:** High-speed programmable logic devices that generate significant localized heat. 3. **Power Electronics:** Voltage regulators or MOSFET modules that require surface area to dissipate heat into the chassis airflow.
