## Technical Analysis of ATS-01F-199-C2-R0 The **ATS-01F-199-C2-R0** is a high-performance heat sink manufactured by **Advanced Thermal Solutions, Inc. (ATS)**. It is part of the "push pin" series designed for cooling electronic components such as CPUs, GPUs, and power modules. --- ### 1. Key Specifications The following table highlights the physical and thermal characteristics of the part: | Feature | Specification | | :--- | :--- | | **Material** | Aluminum | | **Finish** | Blue Anodized | | **Attachment Method** | Push-Pin (Plastic) | | **Thermal Resistance** | 15.83°C/W (at 100 LFM) | | **Dimensions (L x W x H)** | 50.00mm x 50.00mm x 6.00mm | | **Fin Style** | Straight Fin | | **Spring Type** | Compression Spring | --- ### 2. Design Components #### A. The Heat Sink Body * **Low Profile:** With a height of only 6mm, this part is ideal for space-constrained applications or dense PCB layouts. * **Fin Configuration:** It utilizes straight fins which allow for efficient airflow in one direction, typically used in forced-air cooling environments. * **Anodization:** The blue anodized finish is not just aesthetic; it provides surface protection against corrosion and slightly improves radiant heat transfer. #### B. The Mounting System (Push-Pin & Spring) Unlike adhesive-based heat sinks, the **ATS-01F-199-C2-R0** uses a mechanical mounting system: * **Push-Pin:** A plastic pin that snaps into pre-drilled holes in the PCB. * **Compression Spring:** Located around the pin, it provides constant pressure (measured in grams/mm) to ensure a tight interface between the component and the heat sink. * **Benefits:** This system allows for easy removal and re-installation during maintenance, unlike thermal epoxies. --- ### 3. Thermal Performance Analysis Thermal resistance measures how effectively the part moves heat away from the silicon. Performance improves significantly as airflow (LFM - Linear Feet per Minute) increases: | Airflow Velocity (LFM) | Thermal Resistance (°C/W) | | :--- | :--- | | **100 (Natural/Low)** | 15.83 | | **300 (Medium)** | 6.99 | | **500 (High)** | 5.23 | --- ### 4. Implementation Requirements To use this part effectively, the electronic design must include: 1. **PCB Hole Pattern:** Two holes must be drilled into the PCB at a specific distance (usually 43mm apart for this series) to accommodate the push-pins. 2. **Thermal Interface Material (TIM):** While the hardware provides the pressure, a thermal pad or paste (like T766 or Chomerics) must be applied between the chip and the aluminum base to fill microscopic air gaps.
