What is the PCB?
PCB meaning=printed circuit board; The printed circuit board. It is an important electronic component, a support for electronic components, and a carrier for electrical connection of electronic components. Because it is made by electronic printing, it is called a “printing” circuit board. China has thousands of PCB manufacturers that provide differect PCB manufacturing services . some focus on metal core pcb, some focus complex PCB like hdi pcb or 10 layer pcb, bare led printed circuit board.
What is the PCBA?
PCBA = assembly of PCB.Various electronic devices are assembled on the circuit board by a surface encapsulation process. Next is the box assembly, which assembles the assembled PCB with the outer casing to form the finished product. That is to say, the PCB bare board passes through the SMT upper part, and then passes through the entire process of the DIP plug-in, referred to as PCBA. This is a commonly used method in the country, and the standard way of writing in Europe and America is PCB’A, which adds a slant point. PCBA is the bare board with the assembly attached. For new electronic design, normally will go to prototype pcb assembly ( Sample PCBA) to verify designs. then update several time ,and go to mass production if market is good.
What is the difference between PCB and PCBA?
PCB refers to the bare 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)，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. Chip components such as chips are attached to the bare board.
PCBA may be understood as a finished circuit board, and the PCBA can be made only after the process on the circuit board is completed.
PCBA=Printed Circuit Board +Assembly。
That is to say, the bare circuit board passes through the SMT patch, and then passes through the entire process of the DIP plug-in, referred to as PCBA.
bare printed circuit 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 bare printed circuit board.
Standard PCB have no parts on the top and are often referred to as “Printed Wiring Boards (PWB).”
Rayming is China PCBA Manufacturing factory that do bare led printed circuit board and PCB assembly China on one-floor to provide quick turn ,easily quality control service to electronic industry .
