Scientists have discovered an innovative surface treatment for printed circuit boards (PCBs). This new treatment not only improves the corrosion resistance of the PCB’s metal traces but also enhances the adhesion between the metal and the insulating substrate. By applying a special nanocoating during the manufacturing process, the PCBs can better withstand harsh environmental conditions, such as high humidity and extreme temperatures. This advancement is crucial for the reliability of electronic devices used in aerospace, automotive, and industrial control systems, where PCBs need to function properly under challenging circumstances.
