Key Technical Specifications | Parameter | Specification | | :--- | :--- | | **Product Type** | Heat Sink | | **Attachment Method** | pushPIN™ (Spring-loaded) | | **Material** | Aluminum (AL6063) | | **Finish** | Blue Anodized | | **Thermal Resistance (Flowing)** | 22.90 °C/W @ 100 LFM | | **Dimensions (L x W x H)** | 35.00mm x 35.00mm x 10.00mm | | **Pitch / Fin Type** | Fine Pitch / Straight Fin | --- ### 2. Component Analysis #### A. The pushPIN™ Attachment System This part utilizes a specific mounting mechanism that includes: * **Brass Push Pins:** Designed to securely fasten the heat sink to the PCB. * **Compression Springs:** These provide precise, even pressure across the interface to ensure maximum heat transfer without damaging the electronic component. * **Compatibility:** Pre-drilled for specific hole patterns (20mm pitch for this model). #### B. Thermal Interface Material (TIM) The "R0" suffix indicates that the heat sink comes pre-applied with **ATS-PPS-01**, a high-quality thermal interface material. This eliminates the need for manual thermal paste application and ensures a consistent bond between the chip and the aluminum base. #### C. Fin Geometry * **Straight Fin Design:** Optimized for linear airflow. * **Material (AL6063):** Chosen for its excellent thermal conductivity and lightweight properties. --- ### 3.
