The **ATS-08D-68-C2-R0** is a high-performance electronic thermal management component, specifically a **Heat Sink** manufactured by *Advanced Thermal Solutions (ATS)*. It belongs to their "blue ice" or high-performance push-pin series designed for cooling integrated circuits (ICs). --- ### 1. Technical Specifications The following table outlines the mechanical and thermal characteristics of the part: | Feature | Specification | | :--- | :--- | | **Material** | Aluminum (AL6063) | | **Finish** | Blue Anodized | | **Attachment Method** | Push-Pin (Plastic or Brass) | | **Spring Type** | Compression Spring | | **Fin Style** | Straight Fin | | **Dimensions (L x W x H)** | 45mm x 45mm x 15mm | | **Thermal Resistance** | 15.31°C/W (at 0.5 m/s airflow) | | **Number of Fins** | Variable (Optimized for flow) | --- ### 2. Key Components & Materials #### A. The Heat Sink Body (Aluminum 6063) Aluminum is used for its excellent thermal conductivity and lightweight properties. The **Blue Anodized** finish is not just aesthetic; it provides: * Increased surface emissivity (improving radiation heat transfer). * Corrosion resistance. * Electrical insulation to prevent short circuits if contact occurs. #### B. The Attachment System (Push-Pin) Unlike adhesive-based heat sinks, this model uses a mechanical push-pin system: * **Uniform Pressure:** The pre-assembled compression springs ensure constant pressure on the processor, optimizing the interface between the chip and the heat sink. * **Reliability:** Mechanical fasteners are more durable than thermal tape in high-vibration environments. #### C. Thermal Interface Material (TIM) The "R0" suffix typically denotes that the part comes with a pre-applied high-performance **Thermal Interface Material** (usually a phase-change material or thermal pad) on the base to ensure minimal air gaps between the component and the sink. --- ### 3. Application Use Cases This specific heat sink is commonly found in: 1. **Network Switches/Routers:** Cooling high-speed ASICs. 2. **Embedded Systems:** Industrial PCs where mechanical stability is required. 3. **Power Electronics:** Cooling MOSFET arrays or voltage regulators. 4. **Processors:** Used for BGA (Ball Grid Array) packages that require a 45mm footprint. --- ### 4. Thermal Performance Comparison The effectiveness of the ATS-08D-68-C2-R0 is highly dependent on airflow (LFM - Linear Feet per Minute): | Airflow Velocity (m/s) | Thermal Resistance (°C/W) | | :--- | :--- | | 0.5 (Natural/Low) | 15.31 | | 1.0 (Moderate) | 6.60 | | 2.5 (High Speed) | 3.90 | ---
