AOI performs a vital function during the SMT manufacturing line. Its Key functionality is to examine printed circuit boards (PCBs) for defects and anomalies after the soldering process. For your new factory, I recommend to acquire a semi-automated solder paste printing machine PTR-B500. You only put the circuit board manually within the System, and also the scraper within the machine will immediately use the solder paste onto the circuit board. It requires about 10 seconds to complete the printing task of the circuit board. is 360 boards per hour
