XYZ positioning system for automated inspection - wafer / probe cards (clean room), long travels up to 720 mm


High-precision quality inspection for cleanroom applications

This inspection system (shown here without cover) is specially designed for automated quality assurance of large wafers, probe cards and printed circuit boards. The positioning system allows positioning along two linear axes. A high-resolution camera or sensor is moved relative to the sample to inspect geometries, perform measurements and document special quality features. The system is controlled by a separate motion controller for three axes.

Increased throughput by automated and low-maintenance 24/7 inspection

  • Simultaneous inspection of multiple 400 x 400 mm wafers, probe cards and printed circuit boards through travels up to 820 mm
  • Reduced cycle time with speeds up to 150 mm/s and accelerations of 2 m/s2
  • Precise measurement results and enormous quality improvements with repeatability up to 1 µm
  • Low-maintenance 24/7 operation and flexible maintenance concept due to fast system exchange on the granite structure

Optionally expandable:

  • Various travels up to 720 mm
  • Version for clean room ISO 14644-1 (up to class 1 on request)
  • Optionally with motorized Z-axis
  • Connections for dust extraction and rotating belt covers
  • With/without frame and base plate made of granite or aluminum
  • Integration into the customer specific application
  • Immediate use with pre-configured controller incl. exemplary software
