I believe that many people are familiar with PCB circuit boards. They may often hear them in daily life, but they may not know much about PCBA and may even be confused with PCB. So what is PCB? How did PCBA evolve? What is the difference between PCB and PCBA? Let’s take a closer look below.
PCB is the abbreviation of Printed Circuit Board. Because it is made by electronic printing, it is called a “printed” circuit board.
PCB is an important electronic component in the electronics industry. It is the support body of electronic components and the carrier for the electrical connection of electronic components. PCB has been extremely widely used in the production and manufacturing of electronic products. The reason why it can be widely used is that its unique characteristics are summarized as follows:
High wiring density, small size and light weight, which is conducive to the miniaturization of electronic equipment.
Due to the repeatability and consistency of graphics, wiring and assembly errors are reduced, and equipment maintenance, debugging and inspection time are saved.
It is conducive to mechanized and automated production, improves labor productivity and reduces the cost of electronic equipment.
The design can be standardized and facilitate interchange.
PCBA is the abbreviation of Printed Circuit Board + Assembly, which means that PCBA is the entire process of going through the PCB blank SMT upper part and then through the DIP plug-in.
Note: SMT and DIP are both methods of integrating parts on the PCB. The main difference is that SMT does not require drilling holes on the PCB, while DIP requires inserting the PIN pin of the part into the already drilled hole. SMT (Surface Mounted Technology) surface mounting technology mainly uses a mounting machine to mount some micro-sized parts on the PCB board. Its production process is: PCB board positioning, printing solder paste, mounting machine mounting, and reflow soldering. Furnace and finished inspection. DIP means “plug-in”, which means inserting parts on the PCB board. These are parts that are integrated in the form of plug-ins when some parts are large in size and are not suitable for mounting technology. The main production processes are: adhesive application, plug-in, inspection, wave soldering, plate brushing and finished inspection.
From the above introduction, we can know that PCBA generally refers to a processing process, and can also be understood as a finished circuit board. That is, PCBA can only be considered after all the processes on the PCB board are completed. PCB refers to an empty printed circuit board with no parts on it. In general: PCBA is a finished board; PCB is a bare board.
