The **ATS-18F-103-C2-R1** is a high-performance electronic thermal management component, specifically a **Heat Sink** manufactured by *Advanced Thermal Solutions (ATS)*. It belongs to the **maxiFLOW™** series, known for its unique flared fin design. --- ### 1. Technical Specifications The following table highlights the critical physical and thermal characteristics of this specific part number: | Feature | Specification | | :--- | :--- | | **Material** | Aluminum (Blue Anodized) | | **Dimensions** | 40mm x 40mm x 9.5mm | | **Fin Style** | Flared (maxiFLOW™) | | **Thermal Resistance** | 3.69° C/W @ 200 LFM | | **Attachment Method** | pushPIN™ (Brass pins/Springs) | | **Thermal Interface Material (TIM)** | T766 (Pre-applied) | --- ### 2. Design and Engineering Features #### A. Flared Fin Geometry The "maxiFLOW" design features fins that flare outward. This increases the surface area for heat dissipation and decreases air pressure drop, allowing for maximum cooling efficiency in restricted airflow environments. #### B. pushPIN™ Attachment Instead of using messy thermal adhesives or fragile clips, this part uses a **pushPIN™** system. - **Components:** It includes a brass pin and a stainless steel spring. - **Benefit:** It provides a precise, repeatable "firm" attachment force to the processor or component, ensuring optimal contact with the Thermal Interface Material (TIM). #### C. Thermal Interface Material (TIM) The part comes pre-installed with **T766**. This is a high-performance thermal pad/paste that fills microscopic air gaps between the heat source and the heat sink, significantly lowering the contact resistance. --- ### 3.
