A new low profile rotary stage leverages Piezo Ceramic Linear Motor (PCLM) technology for use in handling 300-mm silicon wafers for semiconductor processing. With a profile height of only 32 mm, the PLR-300 allows for a minimal working stack-up height when used with other stages--such as mounted atop and straddling a linear stage. This is very beneficial for minimizing causes of abbe error. Powered by two diagonally opposed PCLMs, the PLR-300 is said to provide superior drive balance and intrinsic smoothness. The PCLM also does not generate heat during operation. The stage is non-magnetic as well and compatible with clean room standards. Angular resolution is ±0.0005 degrees with a positioning accuracy of ±2 microns. Anorad, Product Code 4215.
One way to keep a Formula One racing team moving at breakneck speed in the pit and at the test facility is to bring CAD drawings of the racing vehicle’s parts down to the test facility and even out to the track.
Most of us would just as soon step on a cockroach rather than study it, but that’s just what researchers at UC Berkeley did in the pursuit of building small, nimble robots suitable for disaster-recovery and search-and-rescue missions.
Design engineers need to prepare for a future in which their electronic products will use not just one or two, but possibly many user interfaces that involve touch, vision, gestures, and even eye movements.
