The **ATS-11F-19-C2-R0** is a high-performance electronic thermal management component, specifically a **Heat Sink** manufactured by Advanced Thermal Solutions (ATS). It is part of the "push pin" attachment series designed for cooling integrated circuits (ICs) like BGA, FPGA, and ASICs. ### 1. Technical Specifications Below are the primary physical and thermal characteristics of the part: | Feature | Specification | | :--- | :--- | | **Material** | Aluminum (Al) | | **Finish** | Blue Anodized | | **Base Dimensions** | 45mm x 45mm | | **Height** | 10mm | | **Fin Type** | XCUT (Straight Fin with cross-cuts) | | **Attachment Method** | Push Pin (Brass) | | **Thermal Resistance** | ~9.75 °C/W (at 200 LFM) | | **Thermal Interface Material** | T766 (Pre-applied) | --- ### 2. Key Components & Design Features #### A. XCUT Fin Geometry The "XCUT" design features straight fins that have been cut crosswise. This creates a matrix of pins/blocks. This design is highly effective because: * It allows for **omni-directional airflow**, meaning air can enter the heat sink from any side. * It increases turbulence, which helps strip heat away from the surface more efficiently than standard straight fins in low-flow environments. #### B. Push-Pin Attachment Mechanism Instead of using messy thermal adhesives or tapes, this part uses a mechanical push-pin system: * **Brass Pins:** Provide a secure, high-tension connection to the PCB. * **Built-in Spring:** Ensures consistent pressure between the heat sink and the chip, optimizing thermal transfer and protecting the chip from mechanical shock. #### C. Thermal Interface Material (TIM) The unit comes with **T766** pre-applied to the base. This is a high-performance phase-change material that fills microscopic air gaps between the heat sink and the electronic component to maximize heat conductivity. --- ### 3. Typical Applications This specific heat sink is used in environments where electronic components generate significant heat but have low vertical clearance (due to the 10mm height). * **Networking:** Routers, switches, and base stations. * **Computing:** High-speed processors and graphics chipsets. * **Embedded Systems:** Industrial PC boards where vibration resistance (via push pins) is required. ---
