The **ATS-03B-50-C2-R0** is a specific high-performance heat sink manufactured by **Advanced Thermal Solutions (ATS)**. It is part of their "Blue Ice" series, designed primarily for cooling high-power electronic components like CPUs, GPUs, and FPGAs. --- ### 1. Technical Specifications The following table outlines the physical and thermal characteristics of this specific component: | Feature | Specification | | :--- | :--- | | **Material** | Aluminum | | **Finish** | Blue Anodized | | **Attachment Method** | Push-Pin (2-Pin) | | **Spring Type** | Brass | | **Dimensions (L x W x H)** | 40mm x 40mm x 15mm | | **Thermal Resistance** | ~9.03 °C/W (@ 1.0 m/s airflow) | | **Flow Direction** | Omni-directional (Pin Fin design) | | **Thermal Interface Material** | T766 (Pre-applied Phase Change Material) | --- ### 2. Key Electronic Features #### A. Pin Fin Technology Unlike standard straight-fin heat sinks, the ATS-03B-50-C2-R0 uses a **pin fin** geometry. * **Omni-directional Airflow:** This allows the heat sink to function effectively regardless of the direction of the airflow across the PCB. * **Turbulence Induction:** The pins create micro-turbulence, which breaks down the boundary layer of air and increases the efficiency of heat transfer away from the electronic package. #### B. Push-Pin Attachment Mechanism This part utilizes a mechanical fastening system rather than adhesive tape: * **Spring-Loaded:** The brass springs ensure a specific, constant pressure (Contact Pressure) is applied to the chip. This minimizes air gaps between the chip and the heat sink. * **Reliability:** Mechanical fasteners are preferred in high-vibration environments (like telecommunications or industrial machinery) where thermal tape might fail. #### C. Pre-Applied Thermal Interface Material (TIM) The "C2" suffix indicates that it comes with **T766 phase-change material**. * When the electronic component reaches a certain temperature, the T766 material changes from a solid to a semi-liquid state, filling all microscopic surface irregularities for maximum thermal conductivity. --- ### 3. Common Applications This heat sink is typically found in the following electronic systems: 1. **Network Switches/Routers:** Cooling high-speed processing chips. 2. **Embedded Computing:** Protecting SOCs (System on Chips) in industrial PCs. 3. **Power Supplies:** Dissipating heat from MOSFETs or voltage regulators.
