I've never kept "open bins" of SMT parts. Seems rather dangerous. We either keep them in the tape or in envelopes (or both).
The tweezer LCR meters work well. ;-)

How about a handheld USB camera attached to a little suction grabber?

To get the part back, or out of irrational fear of ingesting a nice safe RoHS part?

I use REAL solder, called 60/40, and often it already has some on it. Sometimes you get interrupted, and had the part sitting on the table, come back, nowhere to be found..... Bit of air flow perps... I am getting better at not losing parts, but also I got a new load of SMDs from ebay. So thing happen... Ayways, 60/40 is almost finished, have to get some new, maybe use rohs for christmas(only). Think it is upstairs next to the plutonium.. ;-)

Ingesting is of no general consequence. Breathing it into your lungs could be an entirely different matter. ...Jim Thompson

That's a thought. Any comments on vacuum pencils vs. tweezers for SMT assembly and rework?
Cheers

I used vacuum "pencils" on my hybrid production line to place microchips 42 years ago. Most of my resistors were thick film, but we occasionally used thin-film _chip_ resistors (SiCr over SiO2 over Si).
I really like the vacuum "pencils". We had Teflon nozzles to avoid metalization scratching. ...Jim Thompson

I've never used vacuum pencils but the usual problem with tweezers is gunk. Flux makes 'em sticky and they don't want to let go of small parts. Alcohol works to clean them, to a point.
The other problem is people trying to bend wire or pick up screws with my tweezers. Hide 'em.
