| - | The system is composed of one main part, the board itself, composed itself of a succession of layers of substrate, insulating material and copper traces. When the PCB has a rigid-flex structure, we can consider that it is composed of a set of rigid PCB board, connected via a set of flexible PCB board. | + | The system is composed of one main part, the board itself, composed itself of a succession of layers of substrate, insulating material and copper traces.
