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.
Conventional wisdom holds that MIT, Cal Tech, and Stanford are three of the country’s best undergraduate engineering schools. Unfortunately, when conventional wisdom visits the topic of best engineering schools, it too often leaves out some of the most distinguished programs that don’t happen to offer PhD-level degrees.
Airbus Defence and Space has 3D printed titanium brackets for communications satellites. The redesigned, one-piece 3D-printed brackets have better thermal resistance than conventionally manufactured parts, can be produced faster, cost 20% less, and save about 1 kg of weight per satellite.
A group of researchers at the Seoul National University have discovered a way to take material from cigarette butts and turn it into a carbon-based material that’s ideal for storing energy and creating a powerful supercapacitor.
