SMT processes constitute the basic elements include: screen printing (or dispensing), Mount (curing), reflow soldering, cleaning, inspection, repair.
 

1, screen: its role is to paste or glue were missing patches to the PCB pad in preparation for welding components. Equipment used for screen printing machine (screen printing), at the forefront of SMT production lines.

2, dispensing: It is the glue dripping fixed position on the PCB, its main role is to fixed components to the PCB board. Equipment used for the dispenser, SMT production lines located behind the front or testing equipment.

3, Mount: its role is to accurately install surface mount components to a fixed location on the PCB. Equipment used for SMT, SMT production line located behind the screen printing machine.

4, Curing: its role is to melt the plastic patch, so that the surface mount components and PCB board firmly bonded together. Equipment used for the curing oven, located behind the SMT placement machine production line.

5, reflow soldering: its role is to melt the solder paste, the surface mount components and PCB board firmly bonded together. Equipment used for reflow furnace, located behind the SMT placement machine production line.
6, cleaning: its role is assembled PCB board above harmful residues such as welding flux, and so removed. Equipment used for the washing machine, the location may not be fixed, online, or not online.

7, detection: its role is assembled PCB board welding quality and assembly quality testing. The equipment has a magnifying glass, microscope, line tester (ICT), flying probe tester, automatic optical inspection (AOI), X-RAY detection system, functional tester. Needed to detect the position of the production line can be configured in the right place.

8, Rework: its role is to detect faulty PCB board rework. The use of iron tools, rework stations and so on. Arranged in the production line anywhere.
