 What is the difference between PCB and PCBA?

The first is the pcb board. Because it is made by electronic printing, it is usually called a printed circuit board. The pcb board is a very important part of the electronics industry, the backbone of the electronic components, and the hub of the electrical connection of the electronic components. PCB has been widely used in the manufacturing of electronic products. The reason why PCB boards are widely used is that PCB boards have their own unique characteristics: high wiring density, small size, light weight, which is conducive to the miniaturization of electronic equipment; due to graphics With repetitive and consistent characteristics, it reduces the difficulty of wiring and assembly, and saves equipment maintenance, debugging and inspection time; at the same time, the pcb board is also more conducive to quantified production and use, which is also a major feature.
The pcba board is the finished product of the pcb board. In layman's terms, the pcba passes through the empty pcb board Wave Solder for PCBA, and then goes through the entire manufacturing process of the DIP plug-in. That is to assemble some parts on the pcb board, and then insert the plug-in on the pcb board to form the final pcba board. The process is more complicated, and the requirements are more. It pays attention to the precision of the product and the manufacturing time. It is relatively long, and the cost-effectiveness of quantitative production is not as high as that of pcb boards. This is also the reason why PCB boards are not widely used in the electronics industry. A pcba is a processing process, which can also be understood as a finished circuit board, which means that the pcba can only be counted after the processes on the pcb board are completed. The pcb refers to an empty custom pcb fabrication.
