What is a PCB?

PCB=printed circuit board; Chinese name for the printed circuit board, also known as printed circuit board, is an important electronic component, is the electronic component support, is the electronic component of the electrical connection carrier. Because it is made using electronic printing, it is called a "printed" circuit board.

What is PCBA?

PCBA=assembly of PCB. Various electronic devices are assembled on a circuit board through a surface packaging process. Next is the box assembly. The assembled PCB will be assembled with the shell to form the finished product. 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. This is a commonly used domestic wording, and the standard wording in Europe and the United States is PCB'A, which is added with oblique points. PCBA is a laminated PCB.

Comparison of PCB and PCBA

What is the difference between PCB and PCBA?

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

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

A printed circuit board (PCB) is called a "printed circuit board." It is made of a glass epoxy resin material and is divided into 4, 6, and 8 layers according to the number of signal layers. The most common are layers 4 and 6. Patch components such as chips are attached to the PCB.

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

PCBA=Printed Cirruit 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.

PCB (Printed Circuit Board) The abbreviation of printed circuit board, usually in the insulation material, according to a predetermined design, made of printed wiring, printed components or a combination of both conductive patterns known as the printed circuit. A conductive pattern that provides electrical connection between components on an insulating substrate is called a printed circuit. In this way, a printed circuit board or a printed circuit board is called a printed circuit board, which is also called a printed board or a printed circuit board.

There are no parts on the top of the standard PCB, and are often referred to as "Printed Wiring Board (PWB)".
