It is believed that many people are not unfamiliar with PCB circuit board, which may be heard often in daily life, but they may not know much about PCBA, and may even be confused with PCB.In general: PCBA is the finished plate;PCB is bare board.So what is a PCB?How did PCBA evolve?What is the difference between PCB and PCBA?The following is the specific understanding of China PCB factory.
What PCB stand for?
Printed Circuit Board Printed Circuit Board Printed Circuit Board Printed Circuit Board Printed Circuit Board Printed Circuit Board Printed Circuit Board Printed Circuit Board Printed Circuit Board Printed Circuit Board Printed Circuit Board Printed Circuit Board Printed Circuit Board Printed Circuit Board Printed Circuit Board Printed Circuit BoardPCB is an important electronic component in the electronics industry. It is the support body of electronic components and the carrier of electrical connection of electronic components.PCB has been widely used in the production and manufacture of electronic products, and its unique characteristics are summarized as follows:
1, high wiring density, small size, light weight, conducive to the miniaturization of electronic equipment.
2. Because of the repeatability and consistency of the figure, the wiring and assembly errors are reduced, and the maintenance, debugging and inspection time of the equipment are saved.
3. It is conducive to mechanized and automatic production, improves labor productivity and reduces the cost of electronic equipment.
4, the design can be standardized, conducive to exchange.
What does PCBA stand for?
PCBA is short for ‘Printed Circuit Board +Assembly’, that is, PCBA goes through the blank PCB SMT and then the whole process of DIP plug-in.
Note: both SMT and DIP are ways to integrate parts on the PCB board. The main difference is that SMT does not need to drill holes on the PCB, but needs to insert PIN PIN of parts into the holes drilled in the DIP.
SMT(Surface Mounted Technology) is mainly used to mount some micro and small parts onto the PCB board. The production process is as follows: PCB board positioning, printing solder paste, mounting, backwelding furnace and manufacturing inspection.
DIP, or “plug-in,” is the insertion of parts into the PCB, which is the integration of parts in the form of a plug-in for larger parts that are not suitable for mount technology.Its main production process is: adhesive, plug-in, inspection, over – wave soldering, brush and make inspection.
What is the difference between PCB and PCBA?
It can be known from the above introduction that PCBA generally refers to a processing process, can also be understood as a finished circuit board, also on the PCB board after the completion of the process can be counted as PCBA.A PCB is an empty piece of printed circuit board with no parts on it.
In general: PCBA is the finished plate;PCB is bare board.
The above is the introduction of the differences between PCB and PCBA. We are specialized in the production of flexible board,flex-rigid,metal core PCB and other products
