The **ATS-19F-145-C2-R0** is a high-performance heat sink manufactured by **Advanced Thermal Solutions (ATS)**. It is part of their "maxiFLOW™" series, specifically designed for cooling electronic components like BGA (Ball Grid Array) packages. ### 1. Technical Specifications Below are the primary physical and thermal characteristics of the part: | Parameter | Specification | | :--- | :--- | | **Part Number** | ATS-19F-145-C2-R0 | | **Material** | Aluminum (Black Anodized) | | **Attachment Method** | maxiGRIP™ (Frame Clip) | | **Dimensions (L x W x H)** | 45mm x 45mm x 30mm | | **Thermal Resistance** | ~1.50 °C/W (at 200 LFM) | | **Pressure Drop** | Low-profile fin design for airflow efficiency | | **RoHS Status** | Compliant | --- ### 2. Key Components & Technologies #### A. maxiFLOW™ Fin Geometry The "F" in the part number often refers to the fin design. ATS uses a tapered fin structure that increases the surface area for heat dissipation while reducing the air pressure drop. This allows more air to flow through the heat sink compared to standard straight-fin designs. #### B. maxiGRIP™ Attachment System This is a critical electronic hardware feature. Instead of using messy thermal adhesives or drilling holes for screws: * **Plastic Frame Clip:** A frame is placed around the component. * **Steady Pressure:** A stainless steel "spring clip" applies even pressure across the chip, ensuring optimal contact with the Thermal Interface Material (TIM). * **Removability:** It allows the heat sink to be removed and reattached during testing or repair without damaging the PCB. #### C. Thermal Interface Material (TIM) The **-R0** suffix typically indicates the inclusion of a pre-applied thermal pad or phase-change material. This eliminates the need for manual application of thermal grease, ensuring a clean and consistent thermal bond. --- ### 3. Application Use Cases This specific heat sink is used in environments where high-power density components are packed closely together, such as: * **Network Switches/Routers:** Cooling high-speed processors. * **Embedded Systems:** For industrial computers where airflow might be restricted. * **Telecommunications:** Cooling FPGA or ASIC chips that generate significant heat (20W-50W+ range depending on airflow). ---
