What is Flush Conductor

A flush conductor is a conductor where the outer surface is positioned in the same plane as the adjacent insulating material. This means that the conductor is situated very close to the surface of the substrate itself, with only a minute fraction of an inch separating them. The flush circuit is achieved by adding epoxy to the surface of a previously etched PCB using specific methods.

The close proximity of the conductor to the substrate surface allows for efficient signal transmission, minimizing the risk of signal interference or loss. Additionally, flush circuits can optimize space utilization on the PCB, making them suitable for compact electronic devices. They contribute to high reliability and cost-effectiveness in PCB design. The flushing process, involving the addition of epoxy to the conductor surface, is a crucial step in designing flush PCBs, ensuring the desired performance and functionality.
