The **ATS-18A-29-C3-R0** is a specific electronic cooling component manufactured by **Advanced Thermal Solutions (ATS)**. It is part of their "maxiFLOW™" series, designed for high-performance heat dissipation in restricted spaces. --- ## 1. Technical Specifications This part is a **Heat Sink** assembly designed primarily for BGA (Ball Grid Array) components. | Feature | Specification | | :--- | :--- | | **Manufacturer** | Advanced Thermal Solutions, Inc. (ATS) | | **Part Series** | maxiFLOW™ | | **Material** | Aluminum (typically Blue Anodized) | | **Dimensions** | 45.7mm x 45.7mm | | **Height** | 20mm | | **Attachment Method** | maxiGRIP™ (Spring-loaded clip) | | **Thermal Resistance** | ~2.30° C/W @ 200 LFM (Linear Feet per Minute) | --- ## 2. Component Breakdown ### A. Physical Geometry The "maxiFLOW" design features a **flared fin structure**. Unlike traditional straight-fin heat sinks, the fins spread outward. This increases the surface area and allows for better airflow intake from multiple directions, which is critical in systems where air direction might be turbulent or inconsistent. ### B. The Attachment System (maxiGRIP™) The "R0" at the end of the part number signifies the attachment mechanism. * **Plastic Frame Clip:** A frame that snaps around the electronic component (CPU, FPGA, or ASIC). * **Steady Pressure:** It uses a high-performance **Gold Vanadium Phosphate (metal)** spring clip to apply constant pressure, ensuring the heat sink stays in contact with the chip without damaging the solder balls. ### C. Thermal Interface Material (TIM) The "C3" designation refers to the thermal pad or grease pre-applied to the base. * **Type:** Phase Change Material (PCM) or high-conductivity thermal tape. * **Purpose:** Fills microscopic air gaps between the chip surface and the aluminum base to maximize heat transfer. --- ## 3.
