Used DISCO DGP 8760 #293619504 for sale

DISCO DGP 8760 is a state-of-the-art wafer grinding, lapping, and polishing equipment specifically designed to process all flat sapphire and glass substrates from 300mm to 8-inch in diameter. It combines advanced, proprietary technology with an easy-to-use touch-screen graphical user interface. The system offers standard grinding, lapping, and polishing operations, along with the ability to perform multi-step process sequences customized to specific applications. Grinding is the removal of material from a sapphire or glass substrate surface to create a desired shape and flatness. The grinding step of DISCO DGP8760 involves polishing the substrate surface to a near-perfect flatness with a maximum warp and bow of 1 micron. It also performs blind grinding to specific depths and tapers. Lapping is the process of using an abrasive material to remove material from the substrate surface in order to create a flat and even surface finish. The lapping process is used to obtain the highest possible quality of surface finish. The lapping step of DGP 8760 creates a final surface quality of 1 Roughness Average (Ra) in one pass. Polishing is the final step of the process, used to obtain a mirror-like finish on the substrate. The polishing process also improves the electrical and optical characteristics of the substrate for further processing. The polishing step of DGP8760 utilizes a unique polishing unit with 8 rotational axes and 8 linear axes. It features adjustable robotic control of the speed and movement of the polisher to ensure a homogeneous, defect-free finish on the substrate. DISCO DGP 8760 is equipped with a 10-stage pre-wash chamber capable of processing a variety of substrates from 300 mm to 8-inch and features adjustable temperature and time settings for customized pre-wash treatments. It also includes an automated slurry changing and cleaning machine to ensure that the machine is properly cleaned before and after each operation. DISCO DGP8760 is specifically designed to provide consistent results and is compliant with the most stringent industry standards. Its advanced and easy-to-use touch-screen graphical user interface allows users to quickly and accurately set all the parameters of the grinding, lapping, and polishing processes. The tool is designed with safety and environmental protection in mind and further ensures the highest production yields and the lowest costs, making it a cost-effective choice for any flat sapphire and glass substrates processing applications.
