Key Technical Specifications | Feature | Specification | | :--- | :--- | | **Material** | Aluminum (Heat Sink) / Brass (Push-Pins) | | **Finish** | Blue Anodized | | **Attachment Type** | Push-Pin (Plastic/Brass) | | **Dimensions (L x W x H)** | 45mm x 45mm x 10mm | | **Thermal Resistance** | 6.47°C/W (Unducted Flow @ 200 LFM) | | **Thermal Interface Material** | T766 (Pre-applied) | --- ### 2. Breakdown of Electronic & Mechanical Parts The assembly consists of several critical components working together to ensure thermal stability: #### A. The Heat Sink Body * **Design:** Features a high-density fin pattern (typically straight-fin or cross-cut) to maximize surface area for heat dissipation. * **Material Choice:** Aluminum is used for its lightweight properties and excellent thermal conductivity. The **Blue Anodized** coating improves surface emissivity and protects against corrosion. #### B. Push-Pin Attachment Mechanism * **Function:** This provides a secure, tool-less mechanical connection to the PCB. * **Componentry:** It consists of a compression spring and a pin. The spring ensures constant downward pressure, which is vital for maintaining a consistent "bond line" between the component and the heat sink. #### C. Thermal Interface Material (TIM) * **Part:** T766. * **Role:** This is a phase-change or high-conductivity pad pre-applied to the base. It fills microscopic air gaps between the electronic component (heat source) and the heat sink base, significantly reducing thermal resistance. --- ### 3. Thermal Performance Profile Thermal performance varies based on the airflow (measured in Linear Feet per Minute - LFM): | Airflow (LFM) | Thermal Resistance (°C/W) | | :--- | :--- | | **100** | 10.14 | | **200** | 6.47 | | **400** | 4.47 | | **600** | 3.53 | --- ### 4. Application Use-Cases * **High-Speed Computing:** Used on chipsets that generate significant heat in compact spaces. * **Networking Hardware:** Ideal for routers and switches where airflow is directional. * **Power Electronics:** Cooling MOSFETs or Voltage Regulator Modules (VRMs) on a PCB.
