The **ATS-02D-91-C2-R0** is a high-performance electronic thermal management component, specifically a **Heat Sink** manufactured by *Advanced Thermal Solutions (ATS)*. It belongs to the "push-pin" attachment family designed for cooling integrated circuits (ICs) and PCB components. --- ### 1. Technical Specifications The following table outlines the physical and thermal properties of this specific part: | Feature | Specification | | :--- | :--- | | **Material** | Aluminum (Al) | | **Finish** | Blue Anodized | | **Attachment Method** | Push-Pin (Plastic/Brass) | | **Fin Style** | Straight Fin | | **Thermal Resistance** | 6.19 °C/W (@ 100 LFM) | | **Dimensions (L x W x H)** | 40mm x 40mm x 10mm | | **Compatibility** | Universal (based on hole spacing) | --- ### 2. Key Electronic Components The "part" itself is a passive mechanical component, but it consists of several integrated elements that work together: #### A. The Heat Sink Body * **High-Aspect Ratio Fins:** The vertical "straight fins" increase the surface area available for heat dissipation. This allows air to flow through the channels, carrying heat away from the sensitive silicon die. * **Aluminum 6063:** This alloy is used for its high thermal conductivity, ensuring heat moves quickly from the base to the fins. #### B. The Push-Pin Attachment System * **Compression Springs:** These provide a specific amount of force (load) to ensure the heat sink remains in constant contact with the component. * **Push-Pins:** These lock into pre-drilled holes on the PCB, providing a more secure mechanical connection than thermal adhesive tapes. #### C. Thermal Interface Material (TIM) * **Pre-Applied Material:** This model usually comes with **T766** or a similar phase-change material applied to the base. This fills microscopic air gaps between the heat sink and the electronic chip, significantly reducing thermal impedance. --- ### 3. Thermal Performance Analysis The efficiency of this part varies based on the airflow (Linear Feet per Minute - LFM) within the electronic enclosure: | Airflow Velocity (LFM) | Thermal Resistance (°C/W) | | :--- | :--- | | 100 (Natural/Low) | 6.19 | | 200 (Medium) | 3.62 | | 400 (High) | 2.55 | | 600 (Ultra) | 2.02 | --- ### 4. Application Use-Cases This part is typically used to cool: 1. **BGA Packages:** High-speed processors or FPGAs. 2. **Northbridge/Southbridge:** Chipsets on motherboards. 3. **Power Electronics:** MOSFET arrays or motor drivers that generate significant waste heat.
