Try this:

for starters. I'm curious and a little confused, though.....how is knowing who made the part going to reduce/eliminate dropped parts?

Or do you mean who manufactured the machine? If so it should have a serial tag, if not it's been butchered by a third party.

Sorry I should have made it more clear. My operators are not identifing the parts after a job is run, all they are doing is bringing me a bag of parts at the end of a shift. By knowing the manufacture, i can look it up in our oracle system to identify the part and return it to stock.

For chip components it is very hard to identify specially the capacitors. You could get sample of each chip manufacture and compare the color. This is very labor intensive task. I suggest to sort by value ( capacitance, resistance) than by manufacturer.

Real solution is to ask your maintenance guy to fix the drop out problem, or else you will have large inventories of drop outs.

Pretty labor intensive operation as has already been mentioned. Bang for your buck is about zilch unless you're dropping expensive stuff at alarming rates.

If you're not doing it already I'd start logging missed picks/drops/rejections and figure out which locations are giving you grief and get it fixed. It's the only cost effective method to deal with it, imho.

Now that I re-read your post, hand that bag back to them and tell them to go through the feeders and figure out where they came from at the end of each job!
