The **ATS-18A-07-C3-R0** is a specific part number for a high-performance **Heatsink** manufactured by **Advanced Thermal Solutions (ATS)**. It is part of their *push-pin* attachment line, designed for cooling electronic components such as CPUs, GPUs, or high-power ASICs. ### 1. Technical Specifications Below are the primary physical and thermal characteristics of this component: | Feature | Specification | | :--- | :--- | | **Material** | Aluminum | | **Finish** | Blue Anodized | | **Attachment Method** | Push-Pin (Plastic) | | **Spring Type** | Compression Spring | | **Thermal Resistance** | 17.09°C/W (at 100 LFM) | | **Dimensions (L x W x H)** | 45mm x 45mm x 12.7mm | | **Fin Style** | Straight Fin | --- ### 2. Key Electronic & Mechanical Components #### A. The Heatsink Body (Thermal Dissipation) The main body is made of extruded aluminum. Its purpose is to increase the surface area of the heat-generating electronic component, allowing ambient air to carry the heat away more efficiently. The **Blue Anodized** coating is not just for aesthetics; it provides corrosion resistance and improves surface emissivity. #### B. Push-Pin Fasteners Unlike adhesive-based heatsinks, the `ATS-18A-07-C3-R0` uses a mechanical push-pin system. - **Material:** Typically Nylon 6/6. - **Function:** These pins snap into pre-drilled holes on the Printed Circuit Board (PCB). They provide a secure, vibration-resistant mount that is more reliable than "peel-and-stick" thermal tape. #### C. Compression Springs Each push-pin is equipped with a spring. This is critical for electronics because: - It maintains **consistent pressure** between the heatsink base and the chip. - It compensates for thermal expansion and contraction during power cycles. - It prevents the heatsink from cracking the delicate die of the electronic component. #### D. Thermal Interface Material (TIM) This specific model usually comes with **T412** thermal tape or a pre-applied phase-change material on the base. This fills the microscopic air gaps between the component and the metal, significantly lowering thermal impedance. --- ### 3. Application Use Cases This part is commonly found in the following electronic environments: 1. **Telecommunications:** Cooling signal processing chips in routers and switches. 2. **Embedded Systems:** Thermal management for industrial PC processors. 3. **Power Electronics:** Dissipating heat from high-current voltage regulators. ---
