How do SMT production lines work?
One fully automatic SMT line machine includes PCB loader, SMT Stencil Printer, Conveyor, Pick and Place Machine, Reflow Oven, SPI, AOI, NG/OK Unloader.
Take our European Automotive Electronics 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.
