I have a Siemens S-27 and I'm having occasional issues with 0201 components in particular. I'm using the 12 segment head and 902 nozzles with them. I'm making sure the magnet is clean of debris and the feeder is sitting flat. Most of the time they run OK, but I'll get a few runs where I'll have several errors. Most of them seem to be "Component not at nozzle after pick", which to me means the part just wasn't there when the nozzle went to pick it. But the other ones I'm getting are "Component not at nozzle before placement", "Vision system not providing measurement results", "Length out of tolerance" and "Width out of tolerance". The actual error description may read slightly differently, but I hope I'm getting the jist of it. I may be missing a manual, but can anyone explain what these descriptions actually mean?
I'm also experiencing what seems to be occasional segment issues. It doesn't happen all the time, but I'll get high error rates using 0201 components on segments 5 and 8. I've replaced the nozzles and segments, but they will still show up. It's very inconsistant and I'm wondering if anyone else has seen this type of issue.
Other component packages run well. When they don't, I can usually pinpoint the reason, but these 0201 issues are difficult to figure out.
Thanks for any help.
