Most of these devices rely on printed circuit boards (PCBs) made of copper, fiberglass, and epoxy resin. These are the flat, ...

Most robots are built out of solid materials like metal and plastic, giving them rigid structures that are easy to work with and understand. But you can open up much wider possibilities if you explore ...

German semiconductor maker Infineon Technologies AG announced that it’s producing a printed circuit board (PCB) that dissolves in water. Sourced from UK startup Jiva Materials, the plant-based ...

While low-cost professional PCB fabrication has largely supplanted making circuit boards at home, there’s still something to be said for being able to go from design to prototype in an afternoon.
