Used IPEC / WESTECH / SPEEDFAM Avanti 472 #9259787 for sale

IPEC / WESTECH / SPEEDFAM Avanti 472 is a wafer grinding, lapping and polishing equipment which incorporates the latest in lapping and polishing technology. It is a fully automatic system with 4-head rotary drive and infrared sensor unit, allowing for uniform grinding, lapping and polishing. The machine utilizes the latest diamond cup wheels and abrasive belts, allowing for precision machining of both planar and 3-D wafers. The tool is designed to process four wafers of up to 6" diameter each, and can handle a variety of materials, ranging from substrates for semiconductors to optical components. The entire asset features an advanced Polishing Head, which locates and maintains the center plane position of the wafer during processing for accurate deformations. This is accomplished by a powerful and highly precise Polishing Head Index that locates the wafer on the plane of the polishing head. The model is capable of achieving Ultra-Smooth Surface Finishes, with a repeatable roughness of up to 20 nanometers. Additionally, it is capable of handling wafers with consistent and precise uniform grids, including those with high concentration of contaminants. The equipment is equipped with an Integrated Safety System that ensures trouble-free operation and includes a tool-less abrasive belt and diamond cup wheel change. Load Monitoring helps the operator to maintain optimal load and process quality, while a contaminant cleaning unit prevents buildup of contamination. The machine also includes a powerful image analysis tool, which enables the user to monitor the asset performance in real-time. Additionally, a CCD Camera can be used to inspect the workpiece quality during the whole grinding and polishing process, enabling defect detection and correction. The image and process parameters can also be recorded during the operation for later inspection and reporting. Overall, IPEC Avanti 472 is a powerful and reliable wafer grinding, lapping and polishing model that makes machining precision wafers with high accuracy and repeatability easy. Its automated control equipment ensures safe and reliable operation and requires minimal setup time. With its excellent performance and advanced technology, it is an ideal solution for manufacturing precision parts in the semiconductor and optical industries.
