Printed circuit board/Printed circuit boards
By definition, a printed circuit board (or PCB) electrically connects and mechanically supports electrical components or electronic components using pads, conductive tracks, and other features etched from one or more sheet layers of copper laminated between or onto sheet layers of a non-conductive substrate.

By definition, a printed circuit board (or PCB) electrically connects and mechanically supports electrical components or electronic components using pads, conductive tracks, and other features etched from one or more sheet layers of copper laminated between or onto sheet layers of a non-conductive substrate.
Generally, components are soldered onto the PCB to both mechanically fasten and electrically connect them to it.
The alternatives to PCB comprise point-to-point and wire wrap construction, both once popular but now rarely used. PCBs require additional design effort to lay out the circuit, but assembly and manufacturing can be automated.

By definition, rigid PCB is inflexible, solid printed circuit board. We are all aware that a PCB may either be single-sided, double-sided, or multilayered. Simultaneously, a printed circuit board can be flexible, rigid, or rigid-flex (a combination of flexible and rigid PCB).
So, a rigid circuit board is something that we cannot force out of shape or bend; it isn’t flexible. A rigid PCB can be single-sided, double-sided, or multilayer. Once a rigid circuit board is fully manufactured, they cannot be folded into or modified to any other shape.
