What is the difference between PCBA and PCB?

What is the difference between PCBA and PCB?
What is the difference between PCBA and PCB? In fact, a finished board is a bare board. Let's first look at their definitions. PCB is called printed circuit board, also known as printed circuit board. It is an important electronic component, a support for electronic components, and a carrier for electrical connection of electronic components. PCBA is to assemble various electronic devices on the circuit board through the surface packaging process. The following editor will take you to further understand the difference between PCBA and PCB.

What is the difference between PCBA and PCB?

PCB refers to circuit board, and PCBA refers to circuit board plug-in assembly, SMT process.  

One is a finished board and the other is a bare board

PCB (Printed Circuit Board) is called "printed circuit board", which is made of epoxy glass resin material. It is divided into 4, 6, and 8 layers according to the number of signal layers. 4 and 6 layers are the most common. SMD components such as chips are pasted on the PCB.  PCBA may be understood as a finished circuit board, which means that PCBA can only be counted after the processes on the circuit board are completed.  

PCBA=Printed Cirruit Board +Assembly.  

That is to say, the empty PCB board goes through the SMT loading, and then goes through the entire manufacturing process of the DIP plug-in, referred to as PCBA.  

PCB (Printed Circuie Board) is an abbreviation of printed circuit board. Usually, a conductive pattern made of printed circuits, printed components or a combination of both on an insulating material according to a predetermined design is called a printed circuit. The conductive pattern that provides electrical connections between components on an insulating substrate is called a printed circuit. In this way, the printed circuit or the finished board of the printed circuit is called a printed circuit board, also called a printed circuit board or a printed circuit board.



The process is the combination of SMT processing and DIP processing. According to the requirements of different production technologies, it can be divided into single-sided SMT placement process, single-sided DIP insertion process, single-sided mixed packaging process, single-sided placement and mixed insertion process Manufacturing process, double-sided SMT placement process and double-sided mixed process and so on.


In summary, the above is the difference between PCBA and PCB shared by the editor. This is also the most basic common sense. After everyone learns it today, there will be no confusion;
