What is the difference between PCB and PCBA?
PCB refers to the circuit board, while PCBA refers to the 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" and is made of epoxy glass resin material. It is divided into 4, 6 and 8 layers according to the number of signal layers. It is most common with 4 and 6 layers. Chip components such as chips are attached to the PCB.
PCBA may be understood as a finished circuit board, and PCBA can only be calculated after the process on the circuit board is completed.
PCBA=Printed Cirruit Board +Assembly.
That is to say, the PCB empty board passes through the SMT upper part, and then passes through the entire process of the DIP plug-in, referred to as PCBA.
PCB (Printed Circuie Board) is an abbreviation for printed circuit board. Generally, a conductive pattern formed on a conductive material according to a predetermined design to form a printed circuit, a printed component, or a combination of the two is called a printed circuit. A conductive pattern that provides an electrical connection between components on an insulating substrate is referred to as a printed circuit. Thus, the finished board of printed circuit or printed circuit is called printed circuit board, also known as printed board or printed circuit board.
Standard PCBs have no parts on the top and are often referred to as "Printed Wiring Boards (PWB)."
