Can a Bare PCB Be Used Directly as a Circuit

A bare PCB (Printed Circuit Board) is a flat board made of insulating material (such as FR-4, a common fiberglass-reinforced epoxy resin) with conductive copper traces etched onto its surface. These traces are designed to connect electronic components, but the question of whether a bare PCB can be u
