What are PCB and PCBA? What is the difference between them?

PCB refers to a blank board, which is the circuit board itself without any components installed. PCBA is the board with components soldered onto it. After the PCB design files (usually in Gerber format) are completed, they are sent to the PCB manufacturer for fabrication of the bare board. The entir
