Silk screen: the role is to solder paste or patch of plastic printed on the pad to the PCB, in order to prepare the welding components. The equipment used for screen printing machine (screen printing machine), SMT production line in the forefront.
Dispensing: It is the glue to the PCB fixed position, its main role is to be fixed to the PCB board components. The equipment used for the dispenser, SMT production line in the forefront or testing equipment behind.
Placement: The role of surface mount components is accurately installed to the PCB fixed position. The equipment used for the placement machine, SMT production line in the back of the screen printing machine.
Curing: its role is to melt the patch glue, so that the surface assembly components and PCB board firmly bonded together. The equipment used is a curing oven, located behind the SMT machine in the SMT production line.
