The difference between PCB and PCBA

///The difference between PCB and PCBA

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

PCB is a bare board, and PCBA is a finished board.

A printed circuit board (PCB) is called a “printed circuit board.” It is made of a glass epoxy resin material. According to the number of signal layers, it is divided into 4, 6, and 8 layers. The most common are 4 layer and 6 layer PCBs.  Patch components such as chips will be mounted on to the PCB.

PCBA may be understood as a finished circuit board, and PCBA can only be counted after the assembly on the circuit board are completed.

PCBA=Printed Circuit Board +Assembly.

In other words, the PCB blank board goes through the SMT and then goes through the entire process of the DIP plug-in, abbreviated as PCBA.

Printed Circuit Board (PCB) The abbreviation of the printed circuit board. Usually, a conductive pattern made of a printed circuit, a printed component, or a combination of the two on an insulating material according to a predetermined design is called a printed circuit. A conductive pattern that provides electrical connection between components on an insulating substrate is called a printed circuit.

There are no components on the top of PCB, which is often referred to as “Printed Wiring Board (PWB).”
