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.
Parallax Inc. is known for developing the Basic Stamp microcontroller development board and educational accessory kits. In addition to developing a user-friendly educational platform to learn about 8-bit microcontrollers and software programming, it created a multicore 32-bit chip called the Propeller.
Researchers working with additive manufacturing have said multimaterial techniques will allow industry “to fabricate materials with combinations of density, strength, and thermal expansion that do not exist [yet].”
