PCB Assembly

　　PCB is the abbreviation of Printed Circuit Board. Translated into Chinese is called printing circuit board. Because it is made of electronic printing, it is called a "print" circuit board. PCB is an important electronic component in the electronics industry. It is the support body of electronic components and a carrier for electronic components electrical connection.

　　PCB has been extremely widely used in the manufacturing of electronic products. The reason why they can be widely applied, its unique characteristics are as follows:

　　1. The wiring density is high, the volume is small, and the weight is light, which is conducive to the miniaturization of electronic equipment.

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

　　3. It is conducive to mechanized and automated production, improves labor productivity and reduces the cost of electronic equipment.

　　4. Design can be standardized and conducive to swap.

　　*About PCBA*

　　PCBA is the abbreviation of Printed Circuit Board +Assembly. That is to say, PCBA is the entire process of PCB empty board SMT parts and then through the DIP plug -in process. Note: SMT and DIP are both integrated parts on the PCB board. The main difference is that SMT does not need to drill on the PCB. In the DIP, the PIN foot of the part is inserted into the well -drilled hole.

　　SMT (Surface Mound TECHNOLOGY) surface paste technology, the main use of the latter is to install some small parts on the PCB board. Inspection of furnace and making. DIP is the "plug -in", that is, inserting parts on the PCB version, which is a large part and not suitable for the form of plug -in to integrated parts when it is installed. Its main production processes are: postplay, plug -in, inspection, peak welding, brushing version and making inspection. * The difference between PCB and PCBA* From the introduction above, it can be known that PCBA refers to a processing process, which can also be understood as the finished line board. It can be counted as PCBA after the process of the PCB board is completed. PCB refers to an empty printing line board with no parts on it.
