Samsung sitck feeder problem

The company that I work for just bought two new Samsung pick and place machines (CP45FV). I love them. But we are having problems with the vibe stick feeders that we have. They have no groves or slots for the parts so if the tubs move at all the placement is off the head tosses the part. The whole point of having parts in tubes is to keep inventory down. Inventory down = cost down. And with our vibes tossing a quarter to half the parts from ever tube we are loosing many high cost parts. Has anyone else run across this problem with the stick feeders on the Samsung P&P machines? If so, how did you solve it? We were using the Phillips GEM P&P machines and had a good system for those vibes. We had interchangeable plates with slots that were added in after we bought them. We have though of trying to update these vibe plates but still haven�t come up with a way to do this. We could sure use some help on this issue. Megan
