## Technical Overview of ATS-19F-75-C1-R0 The **ATS-19F-75-C1-R0** is a high-performance electronic thermal management component, specifically a **Heat Sink** manufactured by Advanced Thermal Solutions (ATS). It is part of the **maxiFLOW™** series, designed to provide efficient cooling for electronic components like CPUs, GPUs, and ASICs. ### 1. Key Specifications | Feature | Specification | | :--- | :--- | | **Part Number** | ATS-19F-75-C1-R0 | | **Material** | Aluminum | | **Finish** | Blue Anodized | | **Attachment Method** | pushPIN™ | | **Thermal Resistance** | 1.48 °C/W (at 200 LFM) | | **Dimensions (L x W x H)** | 45mm x 45mm x 20mm | | **Fin Style** | maxiFLOW (Tapered Fin) | --- ### 2. Functional Components and Features #### A. Fin Design (maxiFLOW™) The "F" in the part number refers to the **maxiFLOW™** fin geometry. Unlike standard straight fins, these are tapered and spread outwards. This design: * Reduces pressure drop. * Increases surface area for heat dissipation. * Maximizes airflow through the heat sink in forced-air environments. #### B. Attachment Mechanism (pushPIN™) The "R0" indicates the inclusion of the **pushPIN™** assembly system. * **Hardware:** Includes a flexible spring and a nylon or brass pin. * **Installation:** Provides a secure, tool-less attachment to the PCB through pre-drilled holes. * **Pressure:** Ensures consistent contact pressure between the heat sink and the electronic component for optimal heat transfer. #### C. Material and Coating * **Aluminum 6063:** Chosen for its excellent thermal conductivity and lightweight properties. * **Blue Anodized Finish:** This is not just aesthetic; anodizing protects the aluminum from corrosion and slightly improves surface emissivity for radiation heat transfer. --- ### 3. Thermal Performance Data Performance varies based on the Air Velocity (Measured in Linear Feet per Minute - LFM): | Air Velocity (LFM) | Thermal Resistance (°C/W) | | :--- | :--- | | 100 | 2.40 | | 200 | 1.48 | | 300 | 1.15 | | 400 | 0.98 | --- ### 4. Application Logic This part is typically used on **BGA (Ball Grid Array)** components. Designers select this specific model when they have a 45mm chip footprint and approximately 20mm of vertical clearance in the chassis.
