The **ATS-04F-19-C2-R0** is a high-performance electronic thermal management component, specifically an **Advanced Thermal Solutions (ATS) push-pin heat sink**. It is designed to dissipate heat from electronic components like CPUs, GPUs, or high-power transistors. --- ### 1. Technical Specifications Below are the primary mechanical and thermal specifications for this part: | Feature | Specification | | :--- | :--- | | **Heat Sink Type** | Fine Pitch (Blue Anodized) | | **Material** | Aluminum (AL6063) | | **Attachment Method** | Push-Pin (Brass) | | **Spring Type** | Compression Spring | | **Thermal Resistance** | 9.77 °C/W (at 100 LFM) to 2.27 °C/W (at 600 LFM) | | **Dimensions (L x W x H)** | 54mm x 54mm x 20mm | | **Thermal Interface Material (TIM)** | T766 (Pre-applied) | --- ### 2. Key Component Breakdown #### A. The Fin Design The ATS-04F-19-C2-R0 utilizes a **straight-fin** geometry. The "fine pitch" design maximizes the surface area within a small footprint, allowing for high-efficiency heat transfer in systems with forced air cooling (fans). #### B. The Push-Pin Attachment Instead of using adhesive tape or screws that go through the PCB, this part uses **brass push-pins** with steel springs. * **Mechanical Stability:** Provides consistent pressure on the component, improving thermal contact. * **Ease of Assembly:** Can be installed manually or via automated equipment by snapping the pins into pre-drilled holes in the PCB. #### C. Thermal Interface Material (TIM) The base of the heat sink comes pre-applied with **T766**. This is a phase-change material or high-performance grease that fills microscopic air gaps between the chip and the heat sink base to ensure optimal heat conduction. --- ### 3.
