You're soldering 0201s? I can't even see the damn
things. Thank god for the ladies in the lab with
good eyesight and steady hands...

1005s (Metric) are 0402s (Imperial) are our "standard" parts but we do
use some 0201s (0603 metric), as well. I've seen 01005s (1/4 again as
big) but haven't used them (don't sneeze!). The 0201s are generally
used as decoupling capacitors so rarely have to be touched.

Interesting. I don't think we have any 0201 caps, our 0201
parts are all resistors. I wish they were all 0402.

0201s fit between BGA pads to keep the caps close to the pins they're
decoupling (minimize inductance). For reliability reasons, they're
not allowed for any other purpose. 0402 is the minimum size, and
everything tends to the smallest possible (cost and space).

And we have 05001s too, but not on any of the stuff I work on.
Thankfully!
