The **ATS-18D-77-C3-R0** is a high-performance electronic thermal management component, specifically a **Heat Sink** manufactured by *Advanced Thermal Solutions, Inc. (ATS)*. It is part of the "pushPIN™" component series designed for efficient cooling of semiconductors and integrated circuits (ICs). --- ## 1. Technical Specifications The part number encodes specific physical and thermal characteristics: | Parameter | Specification | | :--- | :--- | | **Material** | Aluminum | | **Finish** | Blue Anodized | | **Attachment Method** | pushPIN™ (Spring-loaded) | | **Dimensions (L x W)** | 25.00 mm x 25.00 mm | | **Height (Fin)** | 20.00 mm | | **Pitch** | Fine-Pitch | | **Thermal Resistance** | 9.58 °C/W (at 100 LFM) | --- ## 2. Electronic Component Breakdown ### A. The Heat Sink Profile (ATS-18D) The "ATS-18D" designation indicates the frame and fin configuration. This specific model uses a **Straight Fin** design, which is ideal for systems where there is a clear, directional airflow provided by a fan. ### B. Thermal Interface Material (TIM) The suffix **C3** indicates that the part comes pre-applied with a thermal interface material (typically a high-performance thermal grease or pad). This ensures there are no air gaps between the electronic component (like a BGA chip or CPU) and the aluminum base, maximizing heat transfer. ### C. Attachment Mechanism (pushPIN™) Unlike adhesive tapes that can fail under high heat, this part uses a mechanical **pushPIN™** system: * **Spring-loaded:** Provides consistent pressure for optimal thermal contact. * **Vibration Resistant:** Crucial for industrial or automotive electronics where physical movement occurs. * **Hardware:** Usually consists of a brass or plastic pin and a stainless steel compression spring. --- ## 3. Applications in Electronics This component is typically used to cool the following electronic parts: 1. **Microprocessors (CPUs/GPUs):** Small form-factor processors in embedded systems. 2. **ASICs & FPGAs:** Custom logic chips that generate localized high-density heat. 3. **Power Converters:** MOSFETs or power modules requiring surface-area dissipation. --- ## 4.
