Used DISCO DFD 641 #293620708 for sale

DISCO DFD 641 is a scribing / dicing equipment designed to efficiently process wafers while significantly reducing die yield loss. Its primary purpose is to minimize wafer chips from the process. It features a combination of integrated diamond scribing wheel, wheel discharging, and wheel replacement systems for high precision, fast Si scribing. The discharging and wheel replacement systems eliminate the need for manual intervention, providing maximum throughput with minimized die yield loss. DISCO DFD641 is composed of four main components: the diamond blade, its drive controller, the wheel discharging and wheel replacement systems, and the dicing / scribing head unit. The diamond blade is composed of high quality diamond segment bonded onto a carbon steel core, thus ensuring accuracy and consistent scribing quality. Additionally, its high power drive controller helps guarantee a consistent and high speed cutting process. The wheel discharging and wheel replacement systems are the core of the system. The wheel discharging unit collects and deposits the dust and grinding residue generated from the diamond blade while its wheel replacement machine automatically maintains the sharpness of the diamond blade. The wheel replacement tool monitors the wear on the diamond blade and will periodically replace the worn-out portion with a new diamond blade that is stored in a replaceable cartridge. The wheel replacement asset not only minimizes downtime, but also contributes to maximizing the die yield by minimizing chip size. The scribing / dicing head unit is equipped with a high-precision, linear-action scanning driver, providing fast and accurate scribing. It uses computer-controlled pulse number adjustment to generate precise scribing quality and to optimize the process time. With its low noise level, reduced vibration, and high processing throughput, DFD 641 provides top-tier results. Additionally, a patented chip-size detection model can be added on to the equipment to provide a fully automated processing solution. These features set DFD641 apart from other systems, making it an ideal choice for manufacturers who demand top-tier performance and maximum die yield. With its superior features and reliability, DISCO DFD 641 provides a cost-effective and efficient wafer processing solution.
