Used PETER WOLTERS AL3P #9003984 for sale

PETER WOLTERS AL3P is a automated wafer grinding, lapping & polishing equipment specifically designed for use in modern semiconductor manufacturing facilities. This system is engineered to provide high efficiency and productivity for mass production as well as small batches of wafers of up to 200mm diameter. The various components in this unit are designed to be easily integrated into an existing or new production line. The machine comprises a gantry-type Y-axis unit, a C-axis rotary table, a polishing station, a lapping station and a grinding station. The Y-axis unit consists of a robust carriage with recirculating ball screws providing rapid traversing speeds of up to 200m/min. The integrated C-axis rotary table offers high accuracy and repeatability over +/- 0.03 degree rotation. The wafers are clamped and then secured with a spindle drive. The grinding station utilizes a spindle drive that is integrated with a PLC controller for precise grinding with preset grinding parameters. The lapping station is completely automated and integrated with the PLC controller for accurate precision during lapping controlled. An in-situ temperature control tool is also embedded for temperature monitoring with the PLC controller for ensuring uniform lapping results. The polishing station, consisting of up to four polishing heads, is powered by a high-performance brushless motor to provide uniform polishing motion with an average positional accuracy of +/- 1um. This robust and highly efficient asset is also integrated with an optional vision model, enabling flexibility in production. The equipment is equipped with a PC workstation with a user-friendly software interface, making it easy to view production data, monitor production procedures and export data to Excel sheets. Overall, AL3P system is highly efficient, reliable and user-friendly, designed to maximize the productivity of a manufacturing facility while providing optimal and consistent wafer grinding, lapping & polishing results.
