## Overview of ATS-18G-40-C2-R0 The **ATS-18G-40-C2-R0** is a high-performance **heat sink** assembly manufactured by **Advanced Thermal Solutions (ATS)**. It is part of their "maxiFLOW" series, designed specifically for cooling electronic components like CPUs, GPUs, FPGAs, and ASICs in high-airflow environments. --- ### Technical Specifications The following table outlines the physical and thermal characteristics of the component: | Feature | Specification | | :--- | :--- | | **Material** | Aluminum (Black Anodized) | | **Dimensions (L x W)** | 37.00mm x 37.00mm | | **Height** | 17.90mm | | **Attachment Method** | pushPIN™ (Spring-loaded) | | **Thermal Resistance** | 2.15 °C/W @ 200 LFM | | **Fin Style** | High-performance spread fin | | **Compliance** | RoHS and REACH compliant | --- ### Key Electronic & Mechanical Components #### 1. Heat Sink Body (maxiFLOW™) The primary electronic function of this part is **passive thermal management**. The maxiFLOW™ design features a flared fin structure that maximizes the surface area for heat dissipation while reducing pressure drop. This ensures that sensitive semiconductors remain within their Operating Temperature range. #### 2. Attachment System: pushPIN™ Unlike adhesive-based heat sinks, the **-R0** variant uses a mechanical push-pin system. * **Springs:** Provides a consistent "Normal Force" (downward pressure) to ensure the thermal interface material (TIM) is fully compressed. * **Pins:** Usually made of brass or plastic, designed to lock into pre-drilled holes on the Printed Circuit Board (PCB). #### 3. Thermal Interface Material (TIM) The "C2" in the part number indicates the pre-applied thermal material. * **Type:** ATS-54 (High-performance thermal grease or pad). * **Function:** It fills microscopic air gaps between the electronic chip surface and the aluminum heat sink base to lower contact resistance. --- ### Applications in Electronics This specific part is commonly found in: * **Telecommunications:** Networking switches and routers. * **Industrial PC:** Embedded systems where vibration resistance is required (mechanical pins are more secure than tape). * **Power Supplies:** Cooling MOSFETs or power ICs. ---
