Ron,



That is frustrating.  Can you get pics or samples of what you and others would agree that is the worst case? Sort of the point were it should be considered a defect. I have found that with some what subjective criteria if I show or train folks to where the line is than that seems to improve the defect judgement. I have seen where this has lowered defct rates but have also had instances where there was a problem that was overlooked because in my review with a more limited population and I did not see the issue (Murphy's law). 



My perfrence would be pictures that can be given to operators for reference and\or used in procedures.

Subject: [TN] Insufficient Solder





Here is an age old question.  Does anyone here have a sure fire way to combat insufficient solder.  I have tried all teh tecniques from what I know of.  These consist of changing stencil thicknesses, changing pastes, re-training ops to IPC-610-D.  I am at a lost.  It seems that each operator sees insufficient solder differently and it is almost an excuse from them to keep busy and make added "touch up."  I am almost ready to through the category out the door b/c it is so subjective adn people are so fickle.



Any ideas out there?
