Biodegradable Materials for Multilayer Transient Printed Circuit Boards

摘要

Printed circuit boards (PCBs) are essential components of nearly all forms of commercial electronics, where they provide mechanical supports and electrical interconnections for mounted components. Modern PCBs offer multilayer configurations, capable of high frequency signal conduction with minimal transmission loss, and robust, reliable performance in various environmental conditions over extended periods of time. The constituent materials typically include metals such as gold, silver, palladium, tin, and copper, on substrates and inter-layer dielectrics of fiber glass or polyimide, for rigid or flexible [2] PCBs, respectively. These materials are designed explicitly for chemical stability and negligible degradation under long-term use.
