K3 hardware - The Mystery Mods?

Really?

Invented by the Chinese?

They are so clever. !!!

Can it be used it for munching take-out if one is not
building?

Understand about the jab and the flick, etc, but the
hard part (remembering) is that the package is about
the size of half a grain of rice. You need steady
hands and a good disposition. Generally I have to wait
for one of those days to come around. ;-)

So far, only 5 or 6 SMT resistors to remove, a couple
go back on, and two pads are jumpered with a discrete
resistor. This is subject to revisions per the test
group (of which I am not one), expect it will be
optimal when it is released.

The hard part about the jab and flick to me is to be sure that you get
enough heat in there that you are lifting the part and not the pad/trace.
Also you have to be careful that you don't get too much heat there as that
can lift the pad/trace too... :)  

I deal with 0402 sized stuff at work all the time and thank my lucky stars
that we've not yet gone to 0201 or the 01005's that I've seen on some sample
kits!  THOSE ARE SMALL!  0402 isn't too terribly scary especially if board
density is relatively low.  The thing that annoys me is the BGA's with blind
and buried vias!  Cause its always the signal that you need to look at that
is on internal layers all the way from part to part.
