Paper-based PCBs

Printed circuit boards (PCBs) are an important part of the electronics, on which multiple functional components and layers are formed. Moreover, the PCBs serve as a device foundation, taking up a large area of the device, and contributing to the major electronic wastes. Among the range of environmental-friendly and flexible PCB materials, paper has attracted considerable interest because it easily decays without generating environmental problems, and it is flexible, inexpensive, and mass producible with the roll-to-roll manufacturing process. This project will establish an innovative strategy to revolutionize paper-based PCBs for the future green electronics. The work will design an additive process for fabricating multilayer paper-based PCBs, which mainly use the combination of matured paper manufacturing processes such as roll-to-roll printing, soaking, coating, screen-printing, and dipping.
