The **ATS-19G-99-C2-R0** is a high-performance electronic thermal management component, specifically a **Heat Sink** manufactured by *Advanced Thermal Solutions (ATS)*. It belongs to the **maxiFLOW™** series, designed to maximize airflow and thermal dissipation for electronic components like BGAs and CPUs. ### 1. Technical Specifications | Parameter | Specification | | :--- | :--- | | **Manufacturer** | Advanced Thermal Solutions (ATS) | | **Series** | maxiFLOW™ | | **Type** | Top Mount Heat Sink | | **Dimensions (L x W x H)** | 45.00mm x 45.00mm x 20.00mm | | **Thermal Resistance** | 11.50°C/W (at natural convection) | | **Material** | Aluminum (with Blue Anodized finish) | | **Attachment Method** | pushPIN™ (Spring-loaded) | --- ### 2. Core Electronic Features #### A. Thermal Management The primary electronic function of this part is to conduct heat away from a semiconductor device (such as an Integrated Circuit or Power Module) to prevent **thermal throttling** or hardware failure. The low thermal resistance (as low as 1.71°C/W at 400 LFM) ensures high-power components stay within safe operating temperature ranges. #### B. pushPIN™ Attachment System Unlike adhesive-based heat sinks, this part uses the **pushPIN™** system. This provides: * **Constant Pressure:** Ensures optimal contact between the heat sink base and the chip surface. * **Vibration Resistance:** Securely holds the component in place during mechanical stress. * **Reusability:** Can be removed for maintenance without damaging the PCB. #### C. Material and Coating * **Aluminum:** Chosen for its high thermal conductivity and lightweight properties. * **Blue Anodized Finish:** This is not just aesthetic; the anodization protects the aluminum from corrosion and slightly improves heat radiation. --- ### 3. Application Example In a standard PCB design, you might define the mounting holes for this heat sink in your CAD software (like Altium or Eagle). The footprint requires specific hole diameters to accommodate the pushPIN™ springs. ```markdown # Mounting Layout Checklist 1. PCB Hole Diameter: 3.12mm (Standard for pushPIN) 2. Keep-out Zone: 45mm x 45mm + 5mm clearance 3. Thermal Interface Material (TIM): Pre-applied T766 phase-change material ``` ---
