As Evtimov mentioned, it will be dependent on package. It will also be dependent on the specifics of your machines so there is no universal "good" value. You will need to experiment to find the best values for your equipment and components. I would

Thanks again Bobpan for all of your help. I hope some of my questions are dumb ones. Regarding "first", the QA error 0, you were right. In checking the setup, for some reason theta was 65227 instead of the 0 that I thought I had set. Regarding "sec

I'm looking for a typical SMT placement defect rate from others in the field so I can judge whether or not we are in an acceptable range. If I give you a board with 200 components (0603, 0805, SOICs, 20mil MSOPs, tantalums, DPAKs and a few 20mil fin

We are running a Juki SMT line (3RAL and 2080E). I am not sure there is an option for a component verifier. My thought is a barcode/scanner set up and I am in the process of working on this but waiting on Juki response on a file question. We do use
