Used DAS 790B #293667541 for sale

DAS 790B is an automated wafer and mask scrubber designed for use in semiconductor processing applications. This scrubber equipment provides precise cleaning of ion implantation masks, reticle masks, and wafers, as well as other related surfaces. 790B has been especially designed to take the tedious process out of manual scrubbing of wafers and masks during several steps of semiconductor processing. This system utilizes a spray arm with freely controllable liquid nozzles to deliver cleaner onto the mask or wafer surface. Controlling and regulating the liquid flow consistently avoids flooding or over-spraying the surface. This is an important benefit during tasks which require frequent modification of the amount of cleaner being applied, such as wet-etch or electrochemical cleaning. DAS 790B allows users to establish a wide variety of settings to tailor the scrubbing process for any particular application. Digital timer functions allow for precise control over the time of application, and operators can easily adjust parameters such as washing speed and washing height. The programmable parameters of the unit ensure fast and effective scrubbing and cleaning every time. 790B is built with a stainless steel frame to ensure maximum durability. Additionally, the scrubber machine is highly efficient in its use of water evaporative cooling to reduce water consumption and prevent the possibility of water vapour condensation. Both the frame and water-saving feature allow for easy installation and operation in harsh environment and in semiconductor clean rooms. To maintain the delicate components of the tool, DAS 790B is designed with a quick-and-easy access cleaning asset. This includes simplified cleaning train disassembly, and vacuum cleaning options are available for some of the modules for effective maintenance of the model. Finally, 790B has been equipped with advanced safety features. These include deadman sensing technology, anti-slip platforms, and emergency stop buttons. These measures ensure optimal safety and security during use.
