I could help you with the SET features if I saw them. It's been about 4 years so I don't remember them off the top of my head. What you would do (nutshell) is get your non-rotated insertions dead center, then step through to a rotated insertion until

You have received some great feedback so far. I would like to summarize and add a few points regarding maintenance. You should start (as recommended already) by verifying your component library data. Using the default values from the master library i

The experimental way is the best approach for SPI settings and fine tuning. Have a start point of +/- 20%. You build 0402s and machine flags them 35% offset from value. You reflow, perform AOI - everything is fine. You go back and you move tolerance
