Tech-Etch uses photoetching to make a variety of equipment parts with sharper precision than traditionally machined parts. They can make custom light-gauge parts without burred edges in intricate patterns and with precise tolerances. They also make photoetched screens with tapered or straight holes, custom board-level shielding and flexible circuits. The flexible circuits use adhesive or nonadhesive materials. They are made out of materials including beryllium copper, stainless steel, aluminum alloys, titanium, tungsten, nitinol, molybdenum, brass and spring steels, and even polyimide film. They are usually 0.0005 to 0.0300 inch thick, and laser machining is available for parts from 0.030 to 0.125 inch. Laser machining is also available for polyimide laminate drilling and ablating, and a number of other finishing processes are available in-house.
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.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
