The **ATS-08B-77-C2-R0** is a specific high-performance heat sink manufactured by **Advanced Thermal Solutions (ATS)**. It belongs to the **maxiFLOW™** product line, designed for cooling electronic components such as CPUs, GPUs, FPGAs, and ASICs. --- ### 1. Technical Specifications The following table outlines the physical and thermal characteristics of the part: | Characteristic | Specification | | :--- | :--- | | **Material** | Aluminum (Blue Anodized) | | **Dimensions** | 25mm x 25mm x 20mm | | **Attachment Method** | pushPIN™ | | **Thermal Resistance** | 9.30°C/W (Unducted Flow @ 200 LFM) | | **Fin Style** | Tapered Fin (maxiFLOW™) | | **Compliance** | RoHS and REACH Compliant | --- ### 2. Electronic Application & Function While the part is mechanical, it is critical for the reliable operation of electronic systems: * **Heat Dissipation:** It removes thermal energy from semiconductor junctions. In electronics, excessive heat leads to "thermal throttling" or permanent hardware failure. * **Thermal Interface Material (TIM):** This part usually comes with **T766** pre-applied thermal phase-change material, which fills microscopic air gaps between the chip and the heat sink to maximize heat transfer. * **Airflow Optimization:** The "tapered fin" design is engineered to transform high-velocity airflow into a more turbulent pattern, which increases the cooling efficiency compared to standard straight-fin heat sinks. --- ### 3. Mounting Mechanism (pushPIN™) The "R0" suffix refers to the specific attachment kit included. The **pushPIN™** system consists of: 1. **Spring-loaded Pins:** These ensure a consistent and precise "clamping force" against the electronic chip. 2. **Reliability:** Unlike adhesive tapes, mechanical pins prevent the heat sink from shifting or falling off due to vibration or high temperatures. 3. **Compression Springs:** Available in different tensions to provide the exact pressure required for various PCB thicknesses. --- ### 4. Part Number Breakdown Understanding the nomenclature helps in identifying its role in a circuit board assembly: * **ATS**: Manufacturer (Advanced Thermal Solutions). * **08**: Part Series/Footprint. * **B**: Fin height/configuration code. * **77**: Specific dimension/style code. * **C2**: Material/Finish (Blue Anodized Aluminum). * **R0**: Packaging and Attachment type (Standard pushPIN™ assembly).
