Used DISCO DAD 681 #9294714 for sale

DISCO DAD 681 is a scribing/dicing equipment designed for the semiconductor wafer processing industry. The system is capable of supporting a wide range of wafer processing needs, including chip-level scribing and alignment operations, as well as precision dicing operations. DISCO DAD681 unit is designed to provide a highly accurate, repeatable process by combining a powerful motion controller, highly-accurate optics, and a precise robot arm. The machine is built on a sturdy base with variable height adjustment for various wafer sizes; features a precise, multi-axis robot arm; and is powered by a custom-designed motion controller with up to four axes of movement. The motion controller is capable of providing high-speed, highly-accurate positioning and trajectory control, while the laser synchronization unit helps ensure consistent results over large batches by providing continuous loops of feedback. Additionally, the robotic arm features a software-controlled wafer alignment that provides an even more accurate placement of marks and dices. For scribing operations, the tool utilises an IR laser that is precisely controllable and adjustable in power, with a spot size ranging from 1µm to 1.1 mm in diameter, yielding highly detailed marks with high-accuracy. The laser is mounted on DAD 681 robot and is automated by the motion controller, allowing for flexible arguments and precision control of the scribing operations. The asset is also adept for ultra-fine precision dicing operations, which are achieved using the model's onboard gas ablation engine. The engine comprises two heads: one for generating the beam and one for focusing it onto the material, ensuring the highest possible precision dicing. The dicing process is automated through DAD681's CCD camera and fast imaging software which can detect and identify chips and accurately program the dicing operations accordingly. DISCO DAD 681 equipment is easy to use, and comes with a user-friendly GUI that allows for setup and programming of the system. With all of these features, DISCO DAD681 offers reliable and accurate wafer processing operation that is highly repeatable and capable of high throughput and yield.
