The **ATS-04B-18-C2-R0** is a high-performance thermal management component specifically categorized as a **Heat Sink** from Advanced Thermal Solutions (ATS). It is designed to dissipate heat from electronic components like CPUs, GPUs, or power transistors. --- ### 1. Technical Specifications The part number follows a specific nomenclature that defines its physical and thermal properties: | Feature | Specification | | :--- | :--- | | **Material** | Aluminum | | **Finish** | Blue Anodized | | **Attachment Method** | pushPIN™ | | **Dimensions (L x W)** | 35mm x 35mm | | **Height (Fin Height)** | 15mm | | **Thermal Resistance** | 13.38°C/W (Unducted Flow @ 100 LFM) | | **Fin Pattern** | Fine Pitch (Cross-Cut) | --- ### 2. Key Electronic & Mechanical Components #### A. The pushPIN™ Attachment System Unlike adhesive-based heat sinks, this part uses the **pushPIN™** system. This consists of: * **Plastic Push Pins:** Flexible fasteners that snap into pre-drilled holes on the PCB. * **Compression Springs:** These provide precise, uniform pressure (Force) across the interface to ensure maximum thermal contact without cracking the silicon die. #### B. Thermal Interface Material (TIM) * **Pre-Applied:** This specific model typically comes with **T766** thermal phase-change material or a high-performance pad applied to the base. * **Function:** It fills microscopic air gaps between the electronic component (IC) and the aluminum base to lower thermal resistance. #### C. Fin Design (Cross-Cut) The fins are arranged in a "mini-fin" or cross-cut pattern. In electronics, this is critical because: * It allows for **omni-directional airflow**, meaning the cooling efficiency is less dependent on which way the fan is blowing. * It increases the surface area significantly within a small 35mm footprint. --- ### 3. Application Use Cases The ATS-04B-18-C2-R0 is commonly used in: 1. **Telecommunications:** Cooling ASICs in routers and switches. 2. **Embedded Systems:** High-heat processors on industrial motherboards. 3. **Power Electronics:** Dissipating heat from MOSFET arrays or Voltage Regulator Modules (VRMs). ---
