Design and evaluation of bio-based composites for printed circuit board application

We adopted a new approach focusing on the development of greener materials for the printed circuit boards (PCBs) in this study. The bio-based composites from soybean oil resins, chicken feathers, and E-glass fibers could potentially replace the traditional E-glass fiber reinforced epoxy composites used in PCBs. The flame retardancy of the PCB was achieved by halogen-free melamine polyphosphate and diethylphosphinic salt. The essential properties of the bio-composites/bio-PCB were evaluated, including mechanical properties, electrical properties, thermal properties, flammability, and peel strength. The properties were found promising for PCB application.
