The **ATS-08B-39-C2-R0** is a high-performance electronic thermal management component, specifically a **Heat Sink** manufactured by Advanced Thermal Solutions (ATS). It is part of the "pushPIN™" series designed for securing cooling solutions to PCBs (Printed Circuit Boards). --- ### 1. Technical Specifications The following table outlines the physical and thermal properties of this specific part: | Feature | Specification | | :--- | :--- | | **Material** | Aluminum (AL6063) | | **Finish** | Blue Anodized | | **Attachment Method** | pushPIN™ (Spring-loaded) | | **Dimensions (L x W)** | 45mm x 45mm | | **Height** | 12.7mm | | **Fin Style** | Straight Fin | | **Thermal Resistance** | 13.08°C/W (at 100 LFM) | | **Compliance** | RoHS and REACH Compliant | --- ### 2. Component Breakdown The ATS-08B-39-C2-R0 consists of three main electronic/mechanical elements: #### A. The Heat Sink Body The body is constructed from **Aluminum 6063**, which offers high thermal conductivity. The "Straight Fin" design allows for low pressure drop and is optimized for airflow generated by system fans. #### B. The Attachment Mechanism (pushPIN™) Instead of using messy adhesives or permanent solder, this part uses a **brass or plastic push-pin** with a **stainless steel spring**. This provides: * Consistent pressure (clamping force) for optimal heat transfer. * Easy installation and removal for maintenance or rework. #### C. Thermal Interface Material (TIM) The "C2" in the part number indicates the type of Thermal Interface Material pre-applied to the base. * **T766:** This is a high-performance thermal grease that fills microscopic air gaps between the heat sink and the electronic component (CPU, GPU, or ASIC). --- ### 3. Usage Scenarios This part is typically found in: * **Networking Equipment:** Switches, routers, and gateways. * **Industrial PCs:** Compact computing modules. * **Power Supplies:** Cooling MOSFETs and voltage regulators. --- ### 4. Thermal Performance Comparison Thermal resistance decreases as airflow (measured in Linear Feet per Minute - LFM) increases: ```python # Comparison of Thermal Resistance (Approximate) airflow_lfm = [100, 200, 300, 400, 500] resistance_cw = [13.08, 5.12, 3.10, 2.31, 1.91] for flow, res in zip(airflow_lfm, resistance_cw): print(f"Airflow: {flow} LFM | Thermal Resistance: {res} °C/W") ```
