The **ATS-03F-104-C2-R1** is a high-performance heat sink manufactured by *Advanced Thermal Solutions, Inc. (ATS)*. It is designed specifically for cooling electronic components like CPUs, GPUs, or high-power transistors. --- ### 1. Technical Specifications This part belongs to the **pushPIN™** Heat Sink Assembly series, featuring a fine-pitch straight fin design for maximum surface area. | Feature | Specification | | :--- | :--- | | **Material** | Aluminum (AL6063) | | **Finish** | Blue Anodized | | **Attachment Type** | Push-pin (Steel with Brass Finish) | | **Spring Type** | ATS-PPS-03 (Stainless Steel) | | **Thermal Interface** | T766 (Pre-applied Thermal Grease) | | **Dimensions (L x W x H)** | 40mm x 40mm x 25mm | | **Fin Pitch** | Fine Pitch | | **Fin Pattern** | Straight | --- ### 2. Thermal Performance Data Thermal resistance is critical in determining how well the heat sink can dissipate heat into the surrounding air. | Air Velocity (m/s) | Thermal Resistance (°C/W) | | :--- | :--- | | 1.0 m/s (200 LFM) | 2.52 | | 2.0 m/s (400 LFM) | 1.48 | | 3.0 m/s (600 LFM) | 1.15 | --- ### 3. Key Electronic Components & Features * **Push-Pin Mounting:** Unlike adhesive-based heat sinks, the push-pin mechanism provides a consistent, high-pressure contact with the chip. This minimizes air gaps and maximizes heat transfer. * **AL6063 Aluminum:** This specific alloy is used because of its high thermal conductivity and structural integrity. * **Pre-Applied Thermal Interface Material (TIM):** The **T766** grease is already applied to the base, ensuring that the microscopic valleys on the chip surface are filled, reducing thermal resistance right out of the box. * **Blue Anodization:** While aesthetically pleasing, the anodized coating protects the aluminum from corrosion and slightly improves radiant heat emission. --- ### 4.
