① Stir the solder paste to make it suitable for printing and welding;
② Solder paste printing, placing the solder paste on a steel mesh and using a scraper to leak the solder paste onto the PCB pad;
③ SPI, a solder paste thickness detector, can detect the printing situation of solder paste and control the printing effect of solder paste;
④ Placement, placement of SMT components on Feida, and accurate placement of Feida components on PCB pads by the SMT machine head through recognition;
⑤ Reflow soldering involves reflow soldering a pre installed PCB board, which undergoes high temperature inside to heat up the paste like solder paste and turn it into a liquid. Finally, it cools and solidifies to complete the soldering process;
⑥ AOI, automatic optical detection, can detect the welding effect of PCB boards through scanning, and can detect whether the board is normal.
⑦ Repair, repair any abnormalities detected by AOI or manual inspection.
