PCB is short for Printed Circuit Board. PCB is an important electronic component in the electronic industry, is the support body of electronic components, and the electrical connection carrier of electronic components.
PCBA stands for Printed Circuit Board +Assembly, meaning that PCBA consists of the Printed Circuit Board SMT component, and the entire manufacturing process consisting of the DIP plug-in.
PS: Both SMT and DIP integrate parts on the PCB board. The main difference is that SMT does not require drilling on the PCB, while the PIN of the part needs to be inserted into the drilled hole in the DIP.
PCBA generally refers to a processing process, which can also be understood as the finished circuit board. PCBA can only be counted after all the processes on the PCB board are completed. A PCB is an empty piece of printed circuit board with no parts on it.
In a all, PCBA is the finished plate; PCB is bare plate
