Water-Soluble Circuit Boards Could Cut Carbon Footprints By 60 Percent

German semiconductor maker Infineon Technologies AG announced that it's producing a printed circuit board (PCB) that dissolves in water. Engadget reports: 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. A 2022 study by 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
