Hi All, agree 100% on product characteristics SPC, and do find process indicators such as paste Volume, useful to monitor via SPC, the printing process, as printing constitutes "70% cases of SMT defects". We juz purchased a 2nd hand CyberOptics 3D

Andy, I have been "evaluating" some AOI systems. However, some of these are actually SAOI (Semi Automatic Optical Inspection), which is not a problem if that is what fits your process and budget. You can buy a high end system complete with many cam

All SM machines pick components with a vacuum nozzle. Most likely the component is picked in the geometric center, which may not be the center of gravity ( SOT 23, SO 89 ). Any other pick position than the center may be taught upon requirement, but y
