Yep I'd say small to medium at most. I was thinking about picking up one of
the tubes, but then it hit me duh I have a drilling machine and .010" drills,
probably better to take something like an IC tube and make my own tests. I
could easily put in 1000 discrete holes at patterned locations. Likely need
more at the edges since they'll be spreading into areas with no bubbles.
Actually the IC tube for .3" DIPs may be a good thing. Turned upside down it
has a groove between the two humps for the DIP leads. May lose the bottom
1/4"-1/2" but that'd be ok by me for an all in one solution..
Might still need to have the tube lower to give it time to form a good stream
of bubbles, I may do a few tests soon. Just ran back into my aerator pump so I
have the testing materials at hand.
