The full name of SMT is Surface mount technology, Chinese means surface mount technology, SMT equipment refers to the machine or equipment used for SMT processing, different manufacturers according to their own strength scale and customer requirements, configure different SMT production lines, can be divided into semi-automatic SMT production lines and automatic SMT production lines, each SMT production line machinery and equipment is different, but the following SMT equipment is a relatively complete and rich configuration line.

Board loading machine: the PCB board is placed in the shelf and automatically sent to the suction machine

Plate suction machine: suck the PCB and place it on the track and transfer it to the solder paste printing machine

Solder paste printing machine: The solder paste or patch glue is accurately leaked onto the pad of the PCB to prepare for component placement. There are roughly three types of printing machines used for SMT: manual printing machines, semi-automatic printing machines, and fully automatic printing machines.

SPI: SPI is the abbreviation of Solder Paste Inspection, Chinese called solder paste inspection machine, mainly used to detect the quality of PCB board printed by solder paste printing machine, detect the thickness, flatness, printing area, etc. of solder paste printing.

Placement machine: the use of equipment editing program to accurately install the components to the fixed position of the printed circuit board, placement machine can be divided into high-speed placement machine and multi-function placement machine, high-speed placement machine is generally used to mount small chip components, multi-functional useless placement machine mainly placement roll, disc or tubular large components or heterosexual components, characterized by high mounting accuracy, but the placement speed is not as good as high-speed machine.

Docking station: A device for transmitting PCB boards.

Reflow Soldering: Located behind the placement machine in the SMT production line, it provides a heating environment that melts the solder paste on the pads so that surface mount components and PCB pads are firmly bonded by a solder paste alloy.

Lower board machine: through the transmission track, automatically collect PCBA.

AOI: Automatic optical identification system, is the abbreviation of English (Auto Optical Inspection), called automatic optical inspection instrument in China, has now been widely used in the electronics industry circuit board assembly production line visual inspection and replace the previous manual visual inspection. When automatically detected, the machine automatically scans the PCB through the camera, collects images, compares the tested solder joints with the qualified parameters in the database, checks the defects on the PCB after image processing, and displays / marks the defects through the display for maintenance personnel to trim.

X-RAY: Mainly used to test the placement quality of various industrial components, electronic components, and circuits.
