The **ATS-19B-209-C2-R0** is a high-performance electronic thermal management component, specifically a **Heat Sink** manufactured by Advanced Thermal Solutions (ATS). It is part of their "push-pin" series designed for securing the cooling element directly to a Printed Circuit Board (PCB). ### Technical Specifications | Parameter | Specification | | :--- | :--- | | **Manufacturer** | Advanced Thermal Solutions (ATS) | | **Part Number** | ATS-19B-209-C2-R0 | | **Material** | Aluminum (AL6063) | | **Finish** | Blue Anodized | | **Attachment Type** | Push-Pin (Plastic) | | **Fin Type** | XCUT (Cross-cut) | | **Thermal Resistance** | 6.27°C/W (Unducted Flow @ 200 LFM) | | **Dimensions (L x W x H)** | 70mm x 70mm x 10mm | --- ### Core Electronic Components & Features #### 1. Heat Sink Body (XCUT Design) The "XCUT" geometry means the fins are cut in both directions. This design is critical for electronics because it allows for **omni-directional airflow**. Whether the cooling fan is oriented horizontally or vertically relative to the heat sink, the air can pass through the fins effectively. #### 2. Attachment Mechanism (Push-Pin & Spring) Unlike adhesive-based heat sinks, the ATS-19B-209-C2-R0 uses a mechanical attachment system: * **Push-Pins:** These go through pre-drilled holes in the PCB. * **Springs:** Specifically, brass or plastic springs provide **firm, consistent pressure** (clamping force) on the high-speed chip or processor. This ensures maximum contact with the Thermal Interface Material (TIM). #### 3. Thermal Interface Material (TIM) The "C2" in the part number indicates the type of thermal interface pre-applied to the base. * **ATS-NO-TIM:** Some variants come bare, but the standard C2 series usually features a high-performance phase-change material or thermal pad. * **Function:** It fills microscopic air gaps between the electronic component (CPU/GPU/FPGA) and the aluminum heat sink to improve heat transfer. --- ### Applications in Electronics This specific part is used for cooling mid-to-large scale integrated circuits (ICs) that generate significant heat. Common use cases include: * **Networking Equipment:** High-speed routers and switches. * **Power Supplies:** Cooling MOSFETs or power regulators. * **Embedded Systems:** Industrial PCs where mechanical stability (vibration resistance) is required via the push-pin mounting.
