PCB is the printed circuit board, also known as printed circuit board. It is the carrier for the interconnection of electronic components and the backbone of the platform supporting electronic components. PCB, as the most basic component of electronic products, has been widely used in consumer electronics and computers. , Communication tools, medical equipment and other fields.

PCB can be divided into single panel, double panel and multi-layer board. Common multi-layer boards are generally 4-layer boards or 6-layer boards. Complex multilayer boards can reach dozens of layers. PCB boards have high density and high reliability. , Designability, manufacturability, testability and assemblability, which is why PCB boards can be widely used.

PCBA is to assemble various electronic components on the circuit board through the surface packaging process. The PCBA process is the empty PCB board through the SMT upper part, and then the entire manufacturing process of the DIP plug-in. In short, the PCBA is a PCB with a patch.

SMT placement is the process of using high-speed placement machines to mount parts to the PCB. The SMT placement process can be divided into: PCB cleaning, solder paste printing, online SPI inspection, part placement, reflow soldering, online AOI inspection, etc. .

DIP plug-in means that large capacitors and resistors cannot be mounted by machine, but can only be manually plugged in. Its main production process is: sticking adhesive, plug-in, inspection, wave soldering, cutting feet and finished inspection.

The difference between PCB and PCBA:

The PCB board refers to an empty printed circuit board with no components on it, while PCBA refers to a processing process, which can also be understood as a finished circuit board. Only after the processes on the PCB board are completed can it be counted as PCBA. In short: PCBA is a finished board; PCB is a bare board.

Kuaifa Smart Manufacturing can not only provide PCB design, PCB manufacturing, DFMA services, but also provide one-stop PCBA manufacturing services such as SMT chip processing, component procurement, assembly testing, etc. You only need to provide the gerbe file, and the rest is all Give it to us.
