Digital-microphotography technology being developed by Quadrant Engineering Plastic products promises to help predict the machining characteristics of the high-performance plastic board materials used to make CSP test sockets, which will have 4-mil separations between holes versus 10-mil separations today. "With the aid of digital-microphotography," says Quadrant Product Development Manager Richard Campbell, "various machining characteristics of high-performance plastic test sockets can be quickly and clearly observed. With this information, machining conditions can be modified to optimize productivity."
Producing high-quality end-production metal parts with additive manufacturing for applications like aerospace and medical requires very tightly controlled processes and materials. New standards and guidelines for machines and processes, materials, and printed parts are underway from bodies such as ASTM International.
Engineers at the University of San Diego’s Jacobs School of Engineering have designed biobatteries on commercial tattoo paper, with an anode and cathode screen-printed on and modified to harvest energy from lactate in a person’s sweat.
