The **ATS-17B-31-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" series designed for secure attachment to Printed Circuit Boards (PCBs). ### 1. Technical Specifications The following table highlights the core physical and thermal characteristics of this part: | Parameter | Specification | | :--- | :--- | | **Manufacturer** | Advanced Thermal Solutions (ATS) | | **Part Number** | ATS-17B-31-C2-R0 | | **Heat Sink Type** | Push-Pin (Passive Cooling) | | **Material** | Aluminum (AL6063) | | **Finish** | Blue Anodized | | **Thermal Resistance** | 25.25°C/W (Unducted Flow @ 100 LFM) | | **Dimensions (L x W x H)** | 57.90mm x 36.83mm x 5.84mm | | **Thermal Interface Material (TIM)** | T766 (High Performance) | | **Attachment Type** | Push-Pin (Plastic/Brass) | --- ### 2. Key Components & Design Features #### A. Fin Profile (Straight Fin) The "31" series indicates a specific fin pattern designed for optimized airflow. Straight fin heat sinks are ideal for applications where the direction of airflow is consistent across the board. #### B. Attachment Mechanism (Push-Pin) Unlike adhesive-based heat sinks, this model uses a mechanical **push-pin and spring** system: * **Reliability:** Provides constant pressure on the processor/component, ensuring better thermal contact over time. * **Ease of Assembly:** Can be installed manually or via automated pick-and-place machinery. * **Safety:** The spring prevents over-tightening which could crack sensitive silicon dies. #### C. Thermal Interface Material (TIM) The part comes pre-applied with **T766**. This is a phase-change or high-conductivity material that fills the microscopic air gaps between the heat sink base and the electronic component (CPU, FPGA, or ASIC), significantly reducing thermal resistance. --- ### 3. Application Use Cases This specific part is typically found in: * **Telecommunications:** Cooling network switches and routers. * **Embedded Systems:** Industrial PCs and automation controllers. * **Consumer Electronics:** High-speed data processing units where vertical clearance is limited (only 5.84mm tall). --- ### 4. Part Number Breakdown Understanding the ATS nomenclature helps in identifying variants: * **ATS:** Advanced Thermal Solutions. * **17:** Indicates the series/mounting hole pattern. * **B:** Revision or specific geometry indicator. * **31:** Unique identifier for the fin configuration and dimensions. * **C2:** Material/Finish code (Blue Anodized Aluminum). * **R0:** Compliance code (RoHS compliant).
