The Morning After: Water-soluble circuit boards could have a huge impact on e-waste

German semiconductor maker Infineon Technologies announced it's making printed circuit boards (PCBs) that dissolve in water. Sourced from UK startup Jiva Materials, the plant-based Soluboard could provide a new way for the tech industry to reduce electronic waste. Jiva's biodegradable PCB is made of natural fibers and a halogen-free polymer with a much lower carbon footprint. A team at the University of Washington College of Engineering and Microsoft Research created a mouse using a Soluboard PCB as its core. The researchers found the Soluboard dissolved in hot water in under six minutes.
