So after barcoding takes place, is this info sent to the feeder or the outside world (is the feeder just a number that the pick and place machine looks for or does the feeder tell the machine what it has)? I guess if every machine and remote feeder f

We are trying to eliminate/minimize the baking process for high lead-count ICs. We would like to reseal packages containing these parts to minimize exposure to humidity. Anyone have or know of a way to reseal or vacuum pack parts? Any suggested eq

I'd love to see a thread focused on various methodologies used for general inventory management schemes, but primarily on procedures to ensure the proper parts get loaded on the pick and place. We have an Assembleon pick and place, so there is no fe

The only way is to get a whole system that is smart - there are several out there. I had Mycronic towers, Mycronic machines and smart feeders and all is connected together. Plus the machine measures values for all passive components. Once machine mak

We have one, but seem like we hardly use it that much though. I would say it's useful, but not exactly must to have. Most of the models out there would not come with the marking vision system, but you can add it as option. The tricky part of using

My method is not good if accuracy is an issue. Most of our reels come with a guage on the back. It is not a perfect count but with a good eye you can get within a couple hundred on reels of 5k. On the reels shipped with no guage I usually just hold a

Does anyone have a template or a method of approximating remaining part count on a started reel? We are not ready to purchase an electronic parts counter at this point

Ashok Dhawan, an old friend of SMTnet, says: Formula for counting components on SMT tape & reels [spiral belt]: Length = Number of turns * 1/2 * 22/7 * ( dia outer + dia inner), where ... Number of turns = ( dia outer - dia inner) / thickness of
