The **ATS-08B-186-C2-R0** is a high-performance electronic thermal management component, specifically an aluminum heatsink manufactured by **Advanced Thermal Solutions (ATS)**. It is part of the "pushPIN™" series, designed for efficient cooling of semiconductors and integrated circuits (ICs). --- ### 1. Technical Specifications The part number encodes specific physical and thermal characteristics. Here is the breakdown: | Feature | Specification | | :--- | :--- | | **Material** | Aluminum (AL6063) | | **Finish** | Blue Anodized | | **Thermal Resistance** | 2.80°C/W (at 100 LFM) | | **Dimensions (L x W)** | 40.00 mm x 40.00 mm | | **Height** | 25.00 mm | | **Attachment Method** | pushPIN™ (Spring-loaded plastic pins) | | **Pitch (Fins)** | Fine Pitch (Cross-cut design) | --- ### 2. Key Components & Design #### A. The Fin Design The **C2** in the part number indicates a specific cross-cut fin pattern. This design allows for: * **Multidirectional Airflow:** Unlike straight-fin heatsinks, cross-cut fins can accept airflow from any direction, making it ideal for crowded PCB layouts. * **Increased Surface Area:** Maximizes heat dissipation without significantly increasing the footprint. #### B. The pushPIN™ Attachment System This part uses a proprietary mechanical attachment system rather than thermal adhesive. It consists of: * **Brass/Plastic Pins:** Used to secure the heatsink through pre-drilled holes in the PCB. * **Compression Springs:** These ensure constant, even pressure (Force) between the heatsink base and the electronic component, which is critical for thermal transfer. #### C. Thermal Interface Material (TIM) The **R0** suffix indicates that the heatsink comes pre-applied with a high-performance **Thermal Interface Material**. This fills the microscopic air gaps between the chip and the aluminum base to reduce thermal resistance. --- ### 3. Usage Context This component is typically used in the following electronic sectors: 1. **Telecommunications:** Cooling high-speed processors in routers or switches. 2. **Embedded Systems:** Protecting SoCs (System on a Chip) from overheating. 3. **Power Electronics:** Dissipating heat from MOSFETs or voltage regulators. --- ### 4. Thermal Performance Comparison *Performance varies based on airflow speed (LFM - Linear Feet per Minute):* | Airflow Speed (LFM) | Thermal Resistance (°C/W) | | :--- | :--- | | 100 (0.5 m/s) | 2.80 | | 300 (1.5 m/s) | 1.76 | | 500 (2.5 m/s) | 1.41 |
