-===== What not to do =====
-Don't just put the tube into the vibrator and back it off one part-length.
-It will result in a mess :)

-===== Modifying the tube =====
-Instead, you need to notch the end of the tube to hold the part in place. We plan to just reuse the same tube over by 'reloading it' from one end.
-To demonstrate, we'll use a 8 SOIC tube.

-Take one chip out and lay it on top of the tube, then notch the top with a razor blade just before the tail of the chip
-{{:mdcpickandplace:cuttubenotching.jpg|}}
-Now put the chip away
-{{:mdcpickandplace:cuttubenotched.jpg|}}
-Using sharp diagonal cutters, cut at the TOP of the tube from the end to where the notch is. Repeat on the other side
-{{:mdcpickandplace:cuttube.jpg|}}
-Bend the top flap up and cut it off so that any burr is on the top, not impeding the chip.
-{{:mdcpickandplace:cuttubebend.jpg|}}
-When you're done there will be a channel that keeps the chip in place and doesnt let it vibrate off to the side but has space for the nozzle to pick up the chip
