The **ATS-20F-40-C3-R0** is a high-performance electronic thermal management component, specifically a **Heatsink** designed by Advanced Thermal Solutions (ATS). --- ## 1. Technical Specifications This part is a member of the "pushPIN™" heat sink assembly line. Below are the primary technical parameters: | Property | Description | | :--- | :--- | | **Material** | Aluminum | | **Finish** | Blue Anodized | | **Attachment Method** | pushPIN™ (Spring-loaded pins) | | **Thermal Resistance** | 14.71°C/W (at 100 LFM) to 1.35°C/W (at 700 LFM) | | **Dimensions (LxWxH)** | 40.00mm x 40.00mm x 25.00mm | | **Pitch** | Fine Pitch | | **Pattern** | XC-Cut (Cross-cut) | --- ## 2. Key Electronic Features The part is engineered to provide efficient cooling for electronic components like CPUs, GPUs, or power transistors. ### A. XC-Cut Fin Design The "XC-Cut" refers to the cross-cut fin geometry. This design increases the surface area and allows for **multi-directional airflow**, meaning the heatsink performs well regardless of which direction the fan is blowing. ### B. pushPIN™ Attachment Instead of using messy thermal adhesives or complex screws, this part uses a **pushPIN™ assembly**. This includes: * A brass or plastic pin. * A compression spring to ensure consistent pressure (TIM - Thermal Interface Material interface). * A secure fit into pre-drilled holes on the PCB. ### C. Thermal Interface Material (TIM) The "R0" suffix typically denotes that the part comes with **T412** thermal interface material (or equivalent) pre-applied to the base, ensuring immediate heat transfer from the component to the aluminum fins upon installation. --- ## 3. Dimensions Detail For PCB layout planning, the following dimensions are critical: ```yaml Base_Length: 40.00 mm Base_Width: 40.00 mm Height: 25.00 mm Pin_Pitch_X: 33.00 mm Pin_Pitch_Y: 33.00 mm ``` ---
