  What is the difference between PCB and PCBA?

PCB is a printed circuit board. It is an important support for electronic components and a carrier for electrical connection of electronic components. Because it is made by electronic printing, it is called custom pcb fabrication.
What is PCBA?
PCBA is PCB assembly. Various electronic devices are assembled on the circuit board surface packaging process. In other words, the whole process of PCB bare board passing SMT, then DIP plug-in, Wave Solder for PCBA, is called PCBA. This is a commonly used method in China, and the standard writing method in Europe and the United States is PCB'A, which adds a tendency. PCBA is a PCB with components.
What is the difference between PCB and PCBA?
PCB refers to the circuit board PCBA refers to the circuit board plug-in assembly, SMT&Through-Hole Assembly process. One is a finished board and the other is a bare board.
PCB (Printed Circuit Board), made of epoxy glass resin material, it is divided into 4, 6 and 8 layers according to the number of signal layers. Layers 4 and 6 are the most common. Chip components such as chips are connected to the PCB.
PCBA can be understood as a finished circuit board, and PCBA can only be made after the process on the circuit board is completed.
