We are no strangers to PCB circuit boards, and can often be heard in daily life, but perhaps not too familiar with the PCBA, and will even be confused with the PCB. So what is PCB, PCBA is how to evolve out of the PCB and PCBA is the difference between what? Here we specifically to understand.
PCB is Printed Circuit Board for short, translated into Chinese is called Printed Circuit Board, because it is the use of electronic printing technology production, it is known as the “printed” circuit board. PCB is an important electronic component in the electronics industry, is the electronic components of the support body is the carrier of the electrical connection of electronic components. PCB has been widely used in the manufacture of electronic products, the reason why it can be widely used, its unique features are summarized below:
1. High wiring density, small size, light weight, conducive to the miniaturization of electronic equipment.
2. Because the graphics have repeatability and consistency, reducing the wiring and assembly errors, saving the maintenance of equipment, debugging and inspection time.
3. Conducive to mechanization, automated production, improve labor productivity and reduce the cost of electronic equipment.
4. The design can be standardized, conducive to interchangeability.
PCBA is Printed Circuit Board +Assembly of the abbreviation, that is to say, PCBA is after the PCB empty board SMT on the pieces, and then after the DIP plug-in the entire process.
Note: SMT and DIP are integrated parts on the PCB board, the main difference is that SMT does not need to drill holes in the PCB, in the DIP need to insert the parts of the PIN feet have been drilled holes in the SMT (Surface Mounted Technology) Surface Mount Technology, the main use of the mounting machine is a number of small and medium-sized parts are mounted on the PCB board, its production process is: PCB empty board SMT, then after DIP plug-in the entire process. Its production process is: PCB board positioning, printing solder paste, mounting machine mounting, over the soldering furnace and made of inspection. DIP that is, “plug-in”, that is, in the PCB version of the inserted parts, which is a number of parts of larger sizes and does not apply to the mounting technology in the form of plug-in integrated parts. Its main production process is: paste the backing, plug-in, inspection, over the wave soldering, brush plate and made of inspection.
From the above introduction can be known, PCBA refers to a general process, can also be understood as a finished circuit board, PCB board on the process are completed in order to count the PCBA. and PCB refers to a piece of empty printed circuit boards, there are no parts on it. In a nutshell: PCBA is a finished board; PCB is an unprocessed board.
