The **ATS-08D-55-C3-R0** is a high-performance electronic thermal management component, specifically a **Heat Sink** manufactured by *Advanced Thermal Solutions (ATS)*. It belongs to the **pushPIN™** series and is designed for efficient cooling of integrated circuits (ICs) and other heat-generating components on a PCB. --- ### 1. Technical Specifications The following table highlights the core physical and thermal properties of the device: | Feature | Specification | | :--- | :--- | | **Material** | Aluminum (AL6063) | | **Finish** | Blue Anodized | | **Attachment Type** | pushPIN™ | | **Thermal Resistance** | 24.11 °C/W (Unducted Flow @ 100 LFM) | | **Dimensions (L x W)** | 35.00 mm x 35.00 mm | | **Height** | 10.00 mm | | **Pitch** | Fine-Pitch | | **Pattern** | XC (Cross-Cut) | --- ### 2. Key Components & Features #### A. Cross-Cut (XC) Fin Design The "XC" designation refers to the cross-cut fin pattern. Unlike straight fins, cross-cut fins allow for **multi-directional airflow**. This is critical in compact electronic enclosures where air may not flow in a single, predictable path. #### B. pushPIN™ Attachment Mechanism This part utilizes a specialized spring-loaded attachment system: * **Compression Springs:** Ensure consistent pressure (Force) between the heat sink and the component, maximizing thermal transfer. * **Plastic/Brass Push Pins:** Designed to snap into pre-drilled holes in the PCB, reducing installation time and mechanical stress. #### C. Thermal Interface Material (TIM) The part typically comes with **T412** thermal tape or a pre-applied phase-change material. This fills the microscopic air gaps between the heat source (e.g., a CPU or FPGA) and the aluminum base to improve heat conductivity. --- ### 3. Thermal Performance Metrics Thermal resistance varies based on the Air Velocity (measured in Linear Feet per Minute - LFM): | Air Velocity (LFM) | 100 | 300 | 500 | 700 | | :--- | :--- | :--- | :--- | :--- | | **Resistance (°C/W)** | 24.11 | 6.97 | 4.07 | 3.03 | --- ### 4.
