Many friends who are not in the electronics industry often confuse PCB with PCBA. thought it was something. So today [Kezhun Measurement and Control] Xiaobian will explain to you the difference between PCB and PCBA. Although the difference between PCB and PCBA is only one letter, the things they represent are not the same thing at all. Below we briefly look at the definition.
PCB Definition
The full name of PCB is Printed Circuit Board/Printed Wire Board, which is printed circuit board/printed circuit board, referred to as "circuit board". Also known as "PC board".
Principle of PCB
The manufacture of printed circuit boards is to imitate the printing technology of book paper, project the light on the negative film through the film, and then use the chemical etching method to print the copper foil circuit on a piece of hard board. With the advancement of technology, the manufacture of printed circuit boards has become more sophisticated and more complex. If you are interested in the PCB process, you can refer to the article "Introduction to PCB Production Line Process".
Why do electronic products have so many functions now, they are all composed of electronic circuits and electronic components, and these circuits must have a carrier, and PCB is this carrier.
PCB is a board (carrier) printed with electronic circuits. It must also carry electronic components and sit on it without loss of function. It is also responsible for connecting the communication pipes between electronic components. Therefore, if the earth is the carrier, the electronic circuit is the road connecting the towns, and the PCB is the earth that has been covered with roads, and the electronic components are the cities and towns. The PCB board is the carrier of various components, and the electronic processing factory performs the electrical connection of the components on the PCB.
