Used WERNER MATHIS VF 500 #9069956 for sale

WERNER MATHIS VF 500 photoresist equipment is an automated high-precision photoresist panel alignment system designed for advanced semiconductor manufacturing from one of the global leading equipment manufacturers for the same, Mathis Werner. This specific unit has been optimized for solar cell device process applications such as those living in the photovoltaic industry. The machine offers a high degree of automation by consisting of an integrated, non-contact panel recognition tool, and an automated alignment asset coupled with a precision semiautomatic vacuum transfer model. The vacuum transfer equipment allows for quick and reliable transportation of substrates into position with its precision alignment sensors that are designed to handle difficult to transfer substrates, providing industry-leading alignment accuracy. The photoresist panel system uses a patented time of flight and laser process to accurately measure distances in nanometer-level increments and accurately align panels within 1 -2 micrometers. This high level of accuracy overcomes the inaccuracies that are commonly experienced with manual alignment methods. The unit consists of several key components that include a prober head, a frame mount transport, a control unit, and a support platform with a wide range of sensors and actuators including a CCD camera, stepper motors, servo drives, sensors, tribometer, force meter, optical power meter, etc. The prober head has two wafer holders made of ceramics with sapphire tips, specially designed to carry wafers and packages up to 4" and 8". This part also has a large vacuum plane with 90 individually adjustable probes that are able to accurately align and align small substrates. It also contains a unique pressure control machine to maintain substrate height for accurate registration. The frame mount transport unit provides the necessary motion control needed for the motion of the wafer. It contains linear encoders and stepper drivers that are used to dynamically calculate the position and velocity of the substrate during transport. The support platform houses the integrated sensors and actuators, including the CCD camera and laser distance measuring tool. It ensures precise placement of the substrate in the registration area and provides quick and precise positioning with accurate alignment and pre-alignment. Overall, VF 500 photoresist asset offers a great combination of high degrees of accuracy, speed and reliability for numerous applications in the photovoltaic industry. It also offers its users a low cost of ownership through its versatile design, accurate registration and robust customer support.
