Used IPEC / WESTECH / SPEEDFAM Avanti 472 #9182620 for sale

IPEC / WESTECH / SPEEDFAM Avanti 472 is a precision wafer grinding, lapping and polishing equipment designed for production and laboratory applications. The system is capable of grinding up to 450mm wafers to a specified flatness and resolution while removing aggressive particles down to 0.5µm. The unit features fully independent grinding and polishing components, allowing for parallel grinding and polishing operations. The high resolution linear drive and digital servo control allows for superior grinding accuracy and repeatability. The grinding tool is driven at speeds ranging from 30 rpm up to 360 rpm with a peak force of 700 N/cm2 and a total force of 14kN. IPEC Avanti 472 features a four-axis linear drive machine for the grinding component and a separate linear drive tool for the lapping/polishing component. The drive asset provides an exceptionally smooth and reliable motion for both components. The grinding component can be moved in the x, y, and z directions with a programmable resolution of 1µm with a repeatability of 1μm. The lapping/polishing component can be moved in the x and y directions with a resolution of 0.001 μm with a repeatability of 0.1μm. The lapping/polishing component uses a pair of hydrostatic bearing assemblies to accurately move the platens, minimizing deflections and at the same time providing improved thermal performance. The platens are powered by a powerful servo model that is capable of exerting up to 30 kN of force. The platens can be used with a selection of suspension systems, including single-sided, double-sided and hybrid. WESTECH Avanti 472 utilizes a modern multimedia PC with touchscreen interface, providing the user with an easy-to-use graphical user interface for programming and controlling the equipment. The system also includes advanced data acquisition and visualization tools, allowing the user to monitor and analyze the process in real-time. The unit can store up to 25 recipes, including up to 50 parameters each. Overall, Avanti 472 is an advanced precision wafer grinding, lapping and polishing machine designed to produce flawless results. The tool includes many redundant features that allow for optimized performance and repeatable precision. The asset is backed by advanced PC-based software, allowing for easily adjustable settings and real-time process monitoring and analysis.
