SMT production line composition system and mounting machine

SMT production line composition system and mounting machine
This SMT production line is usually composed of multiple equipment with different functions The SMT production line is arranged according to the product requirements Some production lines have high requirements, which requires more testing equipment and high-end equipment Generally, current wiring is common equipment. What are they made of? Let me explain for everyone
In this current patch production and processing, customer requirements are getting higher and higher Therefore, customers must have corresponding equipment to meet the production needs of customers' products Generally, there are three main aspects of SMT chip production line: solder paste printer, chip mounter, and reflow soldering are necessary No matter what products are needed, if you want to distinguish between them, they are only fully automatic or semi-automatic, and the rest of the testing equipment usually includes SPI (Solder Paste Inspection Machine,
Circuit board

Usually, after placing the printer, testing the quality of solder paste printing), AOI (generally placing it after the furniture, testing the welding quality of the circuit board, testing whether there are grape balls, tombstones, bridges, false welding and other phenomena), if it is a high-end manufacturer, there will be X-RAY (similar to a CT machine, which can please the board to see the welding quality of the IC pins), Because the general AOI does not have this function, there are still some customers - the circuit board has many IC pins. After all, it requires X-ray irradiation to see the real welding quality on the display to see whether it is virtual welding or empty welding
In addition to the above three pieces and some commonly used test equipment, the SMT production line also includes some peripheral equipment, such as loading and unloading machinery, docking station, buffer machine, transplanter, splitter, etc These peripheral equipment can be added freely according to product demand and production scale Generally, these peripheral equipment are also relatively cheap
What are the types of mounters
After the SMT machine was introduced into China in the early 1990s, it promoted the processing of Chinese electronic products to become a world processing factory. The SMT machine was called a banknote printing machine in the 1990s and even in the early 21st century. At that time, electronic products flourished. Large batch size and high unit price. With the continuous expansion of the industry, the competition is becoming more and more fierce, and the scientific and technological development of the mounter is becoming stronger and stronger. The placement speed is faster, the placement precision is higher, and the placement size of components is more and more fine.
The placement machine is divided into high-speed machine and multi-function machine according to production capacity
High speed machine means that the theoretical value of placement is more than 50000 points/hour. The main electronic components of high-speed machines are chip components. The functional machine is mainly used to install large data and special-shaped parts.
The placement machine is divided into boom type, rotary table type and composite type according to the structure
The type of suspender is mainly high-precision, which is suitable for connecting large data, especially QFP/BGA companies The boom types are divided into single boom and multi boom types. The multi boom type extends from single boom, and the placement speed will be higher High, two arms can be installed with two PCB circuit boards together
The installation speed of tower mounter is faster than that of boom mounter. However, due to the defects of the machine structure, the large area and the limited installation speed, it is difficult to accelerate.
