Used DISCO DFG 841 #9208229 for sale

DISCO DFG 841 is a modular wafer grinding, lapping, and polishing equipment for silicon, gallium arsenide, sapphire, and other materials. Highly automated and sophisticated, this machine offers owners cost savings in semiconductor production, while maintaining a consistent level of high quality. The system can be used to grind, lap, and polish both single and double side wafers of different diameters. With high precision the unit is capable of producing superior small wafers in a matter of seconds. The Discop DISCO DFG841 is made up of a main housing which holds the main grinding, lapping and polishing systems. The systems are powered by direct current motors to create a smooth and quiet operation. The motors and accompanying motors are also capable of autonomous operation. To further ensure a precision finish, the machine is equipped with a suite of measuring tools, such as a simple 2-axis gauge to detect small wafers imperfections, a profilometer to measure planarity and a step gauge for size measurements. The grinding head of the tool is equipped with a heavy-duty diamond grinding wheel for a precise and efficient grinding process. The adjustable wheel is capable of providing polishing effects to the wafer's surface, ensuring a high level of accuracy. The lapping head of the asset has multiple capacities, allowing to both co-planarize and flatten wafers. Lastly, the polishing head utilizes a series of independent heads with adjustable speeds to provide a superior polish for the wafer. In addition, the or model includes a coolant control unit that uses a recirculating-coolant equipment with a detachable filtration system for efficient cooling. This helps keep the wafers safe against heat damage when grinding, lapping, or polishing. DFG 841 is also designed with safety in mind, featuring a generous array of protective covers and enclosure shielding to prevent accidental contact with hot components and hazardous materials. In order to ensure safety even in instances of power outages, the unit is also equipped with a metal emergency stop switch. The modernized design of DFG841 eliminates the need for manual labor and creates a lower cost of ownership through a more efficient production process. This improves the quality, precision, and uniformity of silicon wafers with improved cycles times.
