Used DISCO DFG 8560 #9289336 for sale

DISCO DFG 8560 is a multi-function, wafer grinding, lapping and polishing equipment designed to improve surface finish, precision profile and flatness of various semiconductor materials. The system is based on a unique hydrostatic technology which utilizes a special grinding oil to eliminate any metal-to-metal contact, thus reducing the effects of wear and tear on the grinding effect. The process starts with grinding and ends with a final step of lapping and polishing with a high precision finish. The grinding unit of the unit is capable of grinding and lapping wafers with an accuracy of one micron (0.001mm) over a disc diameter of 8-inch (203 millimeter). This is highly suitable for precision surface finishing on a wide variety of semiconductor substrates, including quartz, silicon, gallium arsenide, diamond and other composite materials. The grinding head is driven by a high torque servo motor, and is designed to bear a load of up to 500N. It is controlled by a digital signal processor, allowing for complete automation. The grinding head can be moved up, down and sideways in the X, Y and Z axes for precise positioning and control. The machine is capable of producing extremely high and repeatable surface roughness values (Ra) as low as 0.06 microns. The combination of the grinding unit and the lapping/polishing unit enables the user control the disc diameter and its thickness tolerance at the same time. This feature makes it possible to attain high accuracy and uniform results for planarity, profile, and surface finish. The lapping/polishing head is driven by a separate servo motor and can rotate up to 8,000rpm. All operations are performed via digitally programmed commands, although there are manual control options available. The lapping/polishing process can be done in both wet and dry modes. In wet mode, diamond slurry is applied to the wafer while it is being polished or lapped to help reduce the amount of scratches. The slurry can be regularly monitored and adjusted for consistency, thus ensuring consistent processing results over time. DISCO DFG8560 tool is a multifunctional and reliable equipment, suitable for both low cost and premium precision operations and also for commercial use. The asset is engineered and tested to rigid industry standards, with each component tested for durability in order to ensure reliable performance throughout the duration of its lifetime. The model is also capable of being upgraded for more advanced operations, making it a convenient and versatile choice for both single-piece and large-volume production.
