Shenzhen Longgang automatic SMT chip production line, what does it mean?

Shenzhen Longgang Zhouchuan Technology Automatic SMT Chip Production Line SMT Meaning:

Bangchuan technology SMT is a surface mount technology (surface? Framed? The abbreviation of technology is the most popular technology and process in electronic assembly industry at present. ? SMT patch refers to the abbreviation of a series of technological processes based on PCB. ?

The basic process elements of SMT include: screen printing (or dispensing), mounting (curing), reflow soldering, cleaning, inspection and repair.

1. screen printing: its function is to print solder paste or chip glue on the bonding pad of PCB to prepare for the welding of components. The equipment used is a screen printing machine, which is located at the forefront of the SMT production line of Zhouchuan Technology. ?

2. Glue dispensing: Glue is dripped at a fixed position of the PCB, which is mainly used to fix components on the PCB. The equipment used is a dispensing machine, which is located at the front end of the SMT production line of Zhouchuan Technology or behind the testing equipment. ?

3. Installation: Its function is to accurately install the surface assembly components to the fixed position of PCB. The equipment used is a mounter, which is located behind the screen printer of SMT production line. ?

4. Curing: Its function is to melt the chip adhesive, so that the surface mount components and PCB board are firmly bonded together. The equipment used is the curing furnace, which is located behind the mounter in the SMT production line. ?

5. Reflow soldering: Its function is to melt the solder paste, so that the surface assembly components and PCB board are firmly bonded together. The equipment used is a reflow oven, which is located behind the mounter in the SMT production line. ?

6. Cleaning: Its function is to remove welding residues harmful to human body such as flux on the assembled PCB. The equipment used is a cleaning machine, and the location can be not fixed, online or offline. ?

7. Inspection: Its function is to inspect the welding quality and assembly quality of the assembled PCB. The equipment used includes magnifying glass, microscope, on-line tester (ICT), flying needle tester, automatic optical inspection (AOI), X-ray inspection system, function tester, etc. This position can be configured in a suitable position on the production line according to the needs of detection. ?

8. Rework: Its function is to rework the PCB board whose fault has been detected. Tools used include soldering iron, maintenance workstation, etc. Configured at any position of the production line.

The meaning of complete automation:

The products produced by automated production lines should have a large enough output; Product design and technology should be advanced, stable and reliable, and remain basically unchanged for a long time. Using automatic production line in batch production can improve labor productivity, stabilize and improve product quality, improve working conditions, reduce production area, reduce production cost, shorten production cycle, ensure production balance, and have remarkable economic benefits.
