Precision Positioning and Motion Control Product Finder Online – What is the easiest way for you to find the best positioning solution? The printed catalog is a major showcase for PI and, as well as presenting the entire product range, it also acts as a reference for all of our motion solutions. However, to take advantage of the latest products and developments, we recommend using the product finder on the PI website www.pi.ws. How to use the product finder: Select the product type specified by the axes of motion required. Selection of more criteria expands or shortens the list of results....

SEMICONDUCTOR PRODUCTION AND INSPECTION The automation of process steps in production and inspection is steadily on the increase. At the same time, the requirements to accuracy required in motion and positioning are growing. Today, in many industrial areas accuracy levels are needed as they were needed just a few years ago in research institutions. PI with its linear stages, rotation stages, and lifting stages, as well as more complex multi-axis kinematics, offers excellent solutions for industrial applications in many growing markets and even for very general automation tasks with...

PHOTONICS PACKAGING AND OPTICAL ALIGNMENT During production and inspection of components with optical data transmission, it is important to align fibers or fiber arrays for optimum connection with the highest possible accuracy. Position tolerances way under 50 nm are usual and multi-channel inputs e and outputs require simultaneous alignment in several axes. eous In this multi-axis system for wafer inspection and photonics alignment, high speed linear motor or stages are used for the long xy stroke, e while mechanical stages with stepper motors and screw drives are used for the other...

Automated testing procedures ensure quality, e.g., in the production process of printed circuit boards (PCBs). Thereby, the precise control of the forces acting on the sensitive boards as well as the fast capturing and interpretation of measurement data are extremely important INDUSTRIAL MANUFACTURING The field of industrial manufacturing and assembly offers the widest range of applications for the PI micropositioning stages. In many applications the precision requirements keep growing for industrial application. For example, digital printing becomes more and more common. The accuracy of...

LASER MATERIAL PROCESSING Laser cutting for example, often requires lowest tracking errors while following the arbitrary path of the customer’s workpiece. This means very dynamic multi-axis motion that is ideally realized by using linear motor solutions which combine dynamics and accuracy. An additional vertical motion is typically realized using a ball screw stage. For improved dynamics in the Z-direction, a linear motor axis can be equipped with a mechanical, magnetic or pneumatic weight balance. These applications can be served with standard linear stages with a debris protection or with...

Typical 2-axis setup with clear aperture for the scanning of larger surfaces 3-axis combination of linear motor stages. The vertical axis uses weight compensation and it can, therefore, move with high dynamics while, at the same time, offering the best positioning accuracy AUTOMATED OPTICAL INSPECTION (AOI) To increase productivity, it is very common to do a meander scan. While one axis generates a motion with constant speed, the perpendicular axis moves one step to the next line. Pictures are taken during the constant speed motion which leads to high requirements in straightness and...

Precision Positioning and Motion Control - 11

Broad Range of Standard Axes The PI Group has many years of experience in the development and construction of highly complex motion systems with the highest precision classes. The experience gained over the years, mainly from customized solutions, has been transferred to the standard products. As a result, a broad spectrum of standard positioning systems has been established, which offers many options within the individual series such as variable travel ranges, different motors, or adaptations to different ambient conditions such as a vacuum and clean-room environments. Today, the use of PI...
