SMT basic process elements include:

screen printing (or dispensing), mounting (curing), reflow soldering, cleaning, testing, repair

1. Screen printing: Its function is to leak solder paste or patch glue onto the PCB pad to prepare for the welding of components. The equipment used is screen printing machine (screen printing machine), located at the front end of the SMT line.

2, dispensing: it is to drop the glue to the fixed position of the PCB board, its main role is to fix the components to the PCB board. The equipment used is the dispensing machine, which is located at the front end of the SMT production line or behind the testing equipment.
