Distinction between the front side and back side of single-layer PCB

Many people will ask how to distinguish between the circuit side and the component side in a PCB?

We should note that if there are only circuits for a Prototype PCB file and no other character, we should first confirm that whether these circuits should be drawn at the top level or at the bottom level. If it is on the top level, it should be the circuit side in theory; if it is at the bottom, it should be component side. However, this kind of distinction is based in theory. In practice, some of them are just in the opposite way. Therefore, you had better ask the client about it. But for double-layer boards, this is not a problem.

If there are characters on the PCB file, it would be easy to make the differentiation. If the characters are in the front way, it is the front side while it is the back side if the characters are in the opposite way.
