Printed circuit boards (PCBs) form the backbone of modern electronics, yet the materials that give them strength and insulation often rely on hazardous chemistries. The most common substrate, FR-4, is a fiberglass-reinforced epoxy containing compounds such as bisphenol A (BPA), epichlorohydrin, and BADGE—chemicals linked to carcinogenicity, endocrine disruption, and environmental persistence. This project challenged the team to explore safer alternatives to FR-4 that maintain the demanding...
