I've had the most success in a check/double-check set up. Most people will tell you that it's labor intensive, and they're not wrong. However, I suspect that those people have never had to manually change two components on a thousand boards at a sh

Presently we are facing wrong loading of zener diode components in SMT Line. * In the particular product, we have two different part numbers of zener diode but the package and color code is same.Only the voltage is different is there in between two p

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

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

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

What temp. are you planning on baking them? If this is long term process I would recommend that you hav trays made out of an appropriate ESDS material that can withstand your bake temp (such as duropol)for your QFPs. You can have several patterns/pa

Thanks to all. The way I've been doing it has been crude and very similar to your method. I make an imprint of the bottom side and cut out areas where components sit and this imprint transfers over to a cardboard. When it comes time to run the second

Dave is right that this site has several leads on 0402 placements and tombstoning issues. However, I found a new method of determining the pick position. Remove a component and fill the cavity with silly putty. After attempted pick up you should see

What does your software do for providing component polarity in a reference guide?

I am looking for a poster (or anything) that shows Polarity Markings for different SMT Components. I would like something for SMT Operators and SMT Setup to be able to look at when training or when they are questioning the polarity of a part. If anyb
