No acid is used.
In the subtractive process for making PC boards, one of two etchant salt solutions will be used to remove copper from where traces are not desired:
In the additive process for making PC boards, copper will be added where traces are desired by electroplating from a copper sulfate salt solution.
No possible use at all, it is both corrosive to the copper and will BURN the board material!!!
I cannot imagine a modern embedded system that is not built on a printed circuit board.

A printed circuit board (PCB) is a usually flat insulated board with conductors printed on it. It may be single sided, or it may be two sided, or it may have up to 50 internal layers. It is used because it eliminates the time consuming task of hand wiring individual components...they are simply soldered to the PCB.

Electroless Nickel Immersion Gold, a process used in printed circuit board manufacturing to give the PCB a cleaner solder contact.

PCB technologies is an information technology company in Johannesburg, South Africa. A PCB populated with electronic components is called a printed circuit assembly (PCA), printed circuit board assembly or PCB assembly (PCBA). In informal usage, the term "printed circuit board" most commonly means "printed circuit assembly" (with components).
