One fully automatic SMT production line includes PCB loader, Stencil Printer, Conveyor, Pick and Place Machine, Reflow Oven, AOI, NG/OK Unloader.
Take our Russian security camera manufacturer as an example:
They put the PCB board in the Loader, and then the PCB will be transferred to the stencil printing machine for solder paste printing, and then enter the pick and place machine to place components of different sizes on the PCB, and then enter the reflow oven for high-temperature soldering. Finally The produced PCBA enters the unloader.
