Used DISCO DFD 651 #293617698 for sale

DISCO DFD 651 is a scribing and dicing equipment designed for use in semiconductor packaging processes. It utilizes a combination of laser-based scribing and blade-based dicing techniques to create high precision parts that are suitable for use in a variety of applications. Scribing is a process in which a series of high-powered laser pulses are directed at a substrate in precise patterns and depths. This creates a series of parallel, discrete grooves or channels in the material's surface, a net or lattice of microcuts. This is an essential step when preparing substrates for dicing due to the high pressures they must sustain while being cut. DISCO DFD651 employs this scribing process with a high degree of precision and accuracy. Specifically, it makes use of a continuous wave (CW) type of laser to produce a series of regular spaced grooves that can be adjusted for their width, depth and circumferences according to customer needs. This system also offers high processing speeds with a coverage rate of up to 8 mm2 per hour. The second part of DFD-651 is the blade-based dicing process. This process relies on a rotating blade that is positioned at the end of an oscillating arm, similar to the ones used in some cutting machines. As it passes over the scribe marks, the arm vibrates rapidly, which creates a series of tiny cuts into the substrate material. This creates smaller parts that can then be used in various applications such as connectors and semiconductor chips due to the high accuracy of the blade's cuts. DFD 651 also offers several features such as its multi-zone active cooling unit, which keeps the substrate and its surrounding environment temperature stable during the scribing and dicing process. Furthermore, the machine is built with a servo-motor motion control providing great positioning accuracy and repeatability between jobs. Finally, it is also equipped with an advanced imaging tool that allows for the precise alignment of the blade and scribing position, as well as a vision asset for in-process verification. These features make DFD651 an ideal scribing and dicing model for manufacturers and designers looking for optimal performance and accuracy when cutting substrate materials. Its ease of operation, combined with its advanced technologies, make it one of the most reliable and versatile systems in its class.
