As someone else mentioned, those are made by
Schmartboard. I asked on
a homebrewed PCB mailing list how or if trenches like that could be
made on a homebrewed or professionally-made board. The answers ranged
from "maybe" to "yes, but very expensive" to "no".
I could see making a very thick solder mask so that a chip would
naturally settle onto the traces. Schmart says they can do custom
PCB work, but they won't say how much extra their service costs over
a standard PCB.
My gut feeling is that it will loads cheaper to job this out with a
PCB order just to stuff the SMT items and leave the rest for the
customer to handle. I don't like it, but then we don't ask hobbyists
to make their own PCBs either.
More business for the Chinese, I imagine. So I can understand the
P112 kit approach.
