Used DISCO DFD 640 #9279499 for sale

DISCO DFD 640 is a professional grade scribing/dicing equipment designed for the semiconductor industry. The system consists of an automated u-frame (or XY) stage, which can move the wafer horizontally, and a vertical stage suspension, used to hold the wafer during scribing. A precision controller is used to control the motion of the wafer stage and provide accurate fine positioning of the scribe line. To prepare the wafer for scribing, the unit is equipped with an Edge Profiler, which is used to detect the shape and roughness of the wafer's edge and provide data for the machine's positioner to accurately locate the scribe line. An additional attachment allows manual placement of an alignment marker on the wafer that is used by the tool to locate the scribe vector. The actual scribing is performed by a laser scriber. A flexible control cabinet allows for precise adjustment of the scribing beam. The scriber is equipped with four wavelengths (a green (532 nm) and a violet (410 nm) laser, as well as a 650 nm diode laser and a fiber laser set to varying output powers from 100mW to 200mW. DISCO DFD640 is also capable of performing dicing operations. A water-cooled spindle is used to drive two or four motors which feed a diamond edge blade that acts as the tool for dicing the wafer. The z-axis of the spindle can be automatically adjusted for variable cutting depths. The asset also features a monitoring model which is designed to detect any deviations during the scribing and dicing cycles. It can detect these deviations at any time and provide data to the operator to prevent further damage. The combination of these technologies allow DFD 640 to provide highly precise scribing and dicing operations, while still providing maximum efficiency. The equipment is also compatible with a variety of materials, allowing it to be used in many different wafer processing applications. DFD640 is the ideal choice for companies looking for a reliable, accurate, and cost-effective scribing and dicing solution.
