In this paper a summary of our novel research results are presented about advances in producing functional electronic devices on environmentally friendly Printed Circuit Boards. The process of production and selected examples are shown for functional electronics (different RFID cards, with Mifare 1K IC and a functional MP3 player). Avoiding traditional epoxy-based FR4 substrates in production may help in the reduction of harmful e-waste materials. The prototyping and production steps are…
