The quality of the products is constantly monitored by AOI 3D machines (Automatic Optical Inspection) post reflow in line.
3D technology allows to obtain measurements on the volume of the welding joints, accurate coplanarity measurements and read component values, thus obtaining a range of highly accurate inspections.
Furthermore, the SMT lines are equipped with SPI machines (solder paste inspection) in line, for measuring the volume of solder paste on each individual pad, before assembly Pick&Place.
This particular control provides an important qualitative improvement of the welding joints and of the whole assembly process.
