The **ATS-08B-156-C2-R0** is a high-performance electronic thermal management component, specifically a **Heat Sink** manufactured by Advanced Thermal Solutions (ATS). It is designed to dissipate heat from electronic integrated circuits (ICs) to prevent thermal throttling or hardware failure. --- ## 1. Technical Specifications Below are the primary physical and thermal characteristics of this component: | Feature | Specification | | :--- | :--- | | **Material** | Aluminum | | **Finish** | Blue Anodized | | **Attachment Method** | pushPIN™ (Spring-loaded) | | **Dimensions (L x W x H)** | 40mm x 40mm x 25mm | | **Fin Type** | XCUT (Cross-cut) | | **Thermal Resistance** | 4.14°C/W (at 100 LFM) | | **Flow Orientation** | Omnidirectional | --- ## 2. Key Electronic Components & Design The "electronic" functionality of this part is passive, but its design is engineered for specific electronic cooling environments: ### A. The XCUT Fin Pattern Unlike straight-fin heat sinks, the XCUT pattern features cross-cut gaps. This is critical for electronics with **low-airflow or variable airflow directions**, as it allows air to enter and exit from multiple angles, increasing the surface area for heat exchange. ### B. pushPIN™ Attachment System The "R0" suffix often refers to the specific attachment kit. This uses a flexible, spring-loaded mechanism that: * Ensures consistent **interface pressure** on the processor. * Prevents damage to the delicate PCB (Printed Circuit Board). * Accommodates different PCB thicknesses via variable spring tensions. ### C. Thermal Interface Material (TIM) The "C2" in the part number typically denotes that the heat sink comes pre-applied with a **T766 phase-change thermal interface material** or a high-performance thermal grease. This eliminates the microscopic air gaps between the chip and the aluminum, ensuring maximum heat transfer. --- ## 3. Applications in Electronics This specific size (40x40mm) is commonly used for cooling the following electronic parts: 1. **BGA Packages:** High-speed Ball Grid Array chips. 2. **FPGAs/CPUs:** Mid-range Field Programmable Gate Arrays or embedded processors. 3. **Power Supplies:** Cooling MOSFETs or power conversion modules. 4. **Network Switches:** Used on specialized ASICs within telecommunications hardware. ---
