The board wash holding fixture allows open exposure support
for PCBA (Printed Circuit Board Assembly), post solder flux removal via high
pressure hot water spray and hot air-knife impingement. Design simplicity,
along with stainless steel and aluminum construction result in a long-term life
cycle. "V" groove PCBA containment allows the assembly to literally "float"
between the top and bottom washer conveyors, and their associated water and air
streams. This protects the PCBA from the two washer conveyor wire-forms which
tend to snag components causing damaged or missing components. This design,
according to the company, virtually eliminates that rework requirement often
caused by the conveyors and/or the "protective" wire-form cage. This fixture
improves flux removal and post wash drying, and is suitable for use in both the
leaded and lead-free production processes. Open construction allows
significantly improved Post soldering flux removal and process drying, along
with shortened loading/unloading cycle time by virtue of the fixture "clamping"
action resulting from the opposing "V" grooves. A permanently mounted fixture
support base allows vertical capture of fixture and access to rapid loading and
unloading of PCBA's into and out of the fixture. This product allows a significant
cost reduction, quality improvement and performance improvement over the
screened cage alternative.
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.
