Online AOI inspection equipment according to the placement of the SMT line is usually divided into three types:
1. After the first one is on the solder paste printing detection fault of AOI solder paste (such as printing, collapse) called after AOI solder paste printing;
2. The second is in fault detection device pasted on the patch of AOI (offset, missing parts, wrong thing, reverse, asymmetry, double
pieces, pieces, breakage, etc.) is called after the patch AOI.
3. The third one is on the AOI after AOI after reflow soldering and wave soldering, and welding is used to detect device pasted on the
failure of AOI, called after reflow soldering AOI (full inspection AOI)
