PEM surface mount and broaching fasteners
designed specifically for use with PC boards provide a solution to satisfy
component-to-board, board-to-board, and board-to-chassis attachment
families of PEM hardware for PC board applications include
ReelFast surface mount fasteners (threaded or unthreaded nuts and standoffs,
captive panel screws and R'ANGLE right-angle fasteners), broaching fasteners
(internally threaded nuts, threaded or unthreaded standoffs, threaded studs,
panel fastener assemblies and spring-action SNAP-TOP standoffs),
broach/flare-mounted standoffs (offering greater pullout performance), and
SpotFast clinch/broach mount fasteners (for joining metal to boards or plastic
fasteners mount on PC boards in the same manner and at the same time as other
surface mount components prior to the automated reflow solder process and
simply become another board component. Broaching fasteners install into all
types of PC boards and aluminum, acrylic, casting or polycarbonate components
and create a firm, interference-type fit resistant to rotation.
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.
