Used WED WEO 4401 #9198390 for sale

WED WEO 4401 is a wafer handler designed to provide precision controlled wafer movement and alignment for a variety of automated wafer handling applications. WEO 4401 offers a robust construction and is equipped with a state-of-the-art wafer control and drive system that can optimize throughput speeds and minimize cycle times. This handler features a patented double-stacked design that allows two wafers to be aligned and transferred simultaneously, significantly decreasing set up time and ensuring accurate repeatability during set-up. It also enables large wafer sizes to be handled and picked up with ease. WED WEO 4401 handler features a high-speed, multiple-ring vacuum chuck that is designed to accurately and repeatably position and pick up wafers as small as 1 inch in diameter. It has maximum wafer movement speed of up to 15 ips, a resolution of 0.000050 inches for wafer alignment and positioning, and provides up to two degrees of wobble (an angular variation) for compensation of improperly mounted or misaligned wafers. WEO 4401 includes advanced safeguarding features, such as automatic electrically interlocked doors, double retraction gates, guard interlocks, and a positive vacuum monitor, ensuring the operator's safety and helping to prevent damage to the handler and wafers. The handler also includes advanced servo drive technology, offering improved dynamics, highly repeatable motion, and better control. WED WEO 4401 is an ideal wafer handler system for a variety of applications, including fine pitch IC packaging, wet-etching, metrology of wafer substrates, test fixtures for troubleshooting, and high-end MEMS devices assembly. It is backed by a comprehensive three-year warranty and includes enhanced service and support for consumables.
