Water-soluble circuit boards could cut carbon footprints by 60 percent
Jiva’s biodegradable PCB is made from natural fibers and a halogen-free polymer with a much lower carbon footprint than traditional boards made with fiberglass composites. Aby the University of Washington College of Engineering and Microsoft Research saw the team create an Earth-friendly mouse using a Soluboard PCB as its core. The researchers found that the Soluboard dissolved in hot water in under six minutes. However, it can take several hours to break down at room temperature.
In addition to dissolving the PCB fibers, the process makes it easier to retrieve the valuable metals attached to it. “After [it dissolves], we’re left with the chips and circuit traces which we can filter out,” said UW assistant professor Vikram Iyer, who worked on the mouse project.Subscribe to the Engadget Deals Newsletter
