## Technical Overview: ATS-16B-99-C2-R0 The **ATS-16B-99-C2-R0** is a high-performance **heat sink** manufactured by **Advanced Thermal Solutions (ATS)**. It belongs to the **maxiFLOW™** series, which is specifically designed to provide high thermal performance in environments with constrained airflow. --- ### 1. Key Technical Specifications The following table outlines the physical and thermal properties of the component: | Feature | Specification | | :--- | :--- | | **Part Number** | ATS-16B-99-C2-R0 | | **Material** | Aluminum | | **Finish** | Blue Anodized | | **Attachment Method** | pushPIN™ (Spring-loaded) | | **Dimensions (L x W x H)** | 45mm x 45mm x 20mm | | **Thermal Resistance** | 1.15 °C/W (@ 200 LFM) | | **Flow Direction** | Directional (High Spread Fin) | --- ### 2. Functional Components To understand how this part functions within an electronic assembly, we can break it down into three primary elements: #### A. The Heat Sink Body (MaxiFLOW™) * **Fin Geometry:** Unlike standard extruded heat sinks, this part uses a tapered fin design. This increases the surface area while reducing the pressure drop, allowing air to flow through the fins more efficiently. * **Base Plate:** The flat bottom surface makes direct contact with the heat-generating component (e.g., a CPU, FPGA, or GPU). #### B. The pushPIN™ Attachment System This is the mechanical mounting hardware provided with the unit. It typically consists of: * **Brass/Plastic Pins:** Used to secure the heat sink to the PCB. * **Compression Springs:** These ensure a consistent, pre-determined "clamping force" on the electronic component, which optimizes thermal interface performance and prevents damage to the chip. #### C. Thermal Interface Material (TIM) * The **"C2"** in the part number indicates the type of thermal interface material pre-applied to the base. * **C2** signifies that the part comes with **T766**, a high-performance thermal grease, or a similar high-conductivity phase-change material to fill microscopic air gaps between the sink and the chip. --- ### 3. Application Use Cases This specific heat sink is commonly found in: 1. **Telecommunications:** High-speed routers and switches. 2. **Embedded Computing:** Industrial motherboards and single-board computers (SBCs). 3. **Power Electronics:** Cooling for MOSFETs or high-density power modules.
