SMT basic process
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.
3. Mounting: Its function is to accurately install the surface
assembly components to the fixed position of PCB. The equipment
used is the SMT machine, which is located behind the screen
printing machine in the SMT production line.
4, 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 the curing furnace, which is located behind the
SMT machine in the SMT line.
