Let’s take a look at pcb board design and pcba
I believe that many people are familiar with pcb board design and may often hear it in daily life, but they may not know much about PCBA and even confuse it with printed circuit boards. So what is pcb board design? How has PCBA evolved? How is it different from PCBA? Let’s take a closer look.
*About pcb board design*

Because it is made of electronic printing, it is called a “printed” circuit board. The pcb board is an important electronic component in the electronics industry, a support for electronic components, and a carrier for electrical connection of electronic components. PCB boards have been widely used in the production and manufacture of electronic products. Its unique characteristics can be summarized as follows:

1. High wiring density, small size and light weight are conducive to the miniaturization of electronic equipment.

2. Due to the repeatability and consistency of the graphics, the errors of wiring and assembly are reduced, and the time of equipment maintenance, debugging and inspection is saved.

3. It is beneficial to mechanized and automated production, improve labor productivity, and reduce the cost of electronic equipment.

4. The design can be standardized for easy interchangeability.

*About PCBA*

PCBA is the abbreviation of printed circuit board + assembly, that is to say, PCBA is the whole process of attaching the upper part of the blank board of the printed circuit board and dipping.

NOTE: Surface mount and die mount are both methods of integrating devices on a printed circuit board. The main difference is that surface mount technology does not require drilling holes in the printed circuit board, the pins of the part need to be inserted into the drilling holes of the DIP.

Surface Mount Technology (SMT) Surface mount technology mainly uses a pick and place machine to mount some tiny components on a printed circuit board. Its production process includes PCB positioning, solder paste printing, placement machine installation, reflow oven and manufacturing inspection.

DIPs are “plug-ins”, i.e. inserting parts on a printed circuit board. These parts are large in size and not suitable for installation technology and are integrated in the form of plug-ins. The main production processes are: adhesive, plug-in, inspection, wave soldering, brush plating and manufacturing inspection.

*Differences between PCBs and PCBAs*

From the above introduction, we can know that PCBA generally refers to the processing process, and can also be understood as a finished circuit board. PCBA can only be calculated after all processes on the printed circuit board have been completed. A printed circuit board is an empty printed circuit board with no parts on it.
