The advanced dual light source inspection provides the highest solder paste reflectivity. For flaw detection, The solder paste can be detected from all angles without shadows, and the thickness of the solder paste can be measured more accurately. There will be no misjudgment caused by the shadow effect caused by unilateral projection JET 6500S SPI adopts stop-and-go imaging, dual-vector measurement light source without shadow interference, plus RGB color ring light and coaxial light source, can accurately measure the printing quality of various sheets. After the introduction of JET 6500S, it can realize multi-machine control by one person, saving personnel allocation and reducing labor costs.
