As the name suggests, single-sided printed circuit boards have just one layer of conductive material on one side, while the other side houses various electronic components. Constructed with a base layer of dielectric called EPOXY, a conductive layer of Copper, and finally, a protective solder mask, these boards are appreciated for their simplicity. Despite technological advancements, single-sided circuit boards are widely in consumer electronics used due to their straightforward design and cost-effectiveness.
