In our production line we use the pick and placer My100 by Mycronics. We get a lot of feedback from quality department about IC's being placed upside down, wrong polarity. (Wrong polarity usually already delivered to us, or IC's placed in the sticks

We are running a Mydata (Micronic) MY15E. The MY100 is the next generation after the MYxxE series. As far as I know, there is no way for the machine itself to check the polarity of ICs to see if 1 or more are in the tube or reel different from all

For upside down and rotated parts try using the index mark (F6) in the package database for that component, at least then the machine should look for a unique feature on the bottom and if it cannot find it the part will be rejected. For the index ma

Been following this thread and have a question, Why do "touch-up" people follow different criteria than "Q.C." people. It sounds like the root of the problem is not addressed but bandaids are being put into place. We have no "Q.C." department and

You see? Chunks, here has the right idea! To the original poster, you need to show this post to your "Desk Jockey" Process Engineer. That's the problem with some Engineers today. They forget everything they learned in Engineering school, they get
