e14/Embest have been building these for quite some time, but only selling to
China
The creation date on this article is Apr 18, 2013:

Now it may be that they're tuning a process on a new production line that's
been spun up to meet demand, but that's no reason to think they don't know what
they're doing. It is obviously a different process to CircuitCo as some of your
earlier observations show. We also don't know how many of these boards embest
have already sold in China in the last year.
Thanks, I wasn't aware of that. Then they're obviously using lower
quality standards for their TH soldering process.
Received one today, given that it has an AM3358 and the R8/R9 change then it
appears to be a RevB equivalent. Older version of Angstrom, but that'll be
getting wiped in the next few mins anyway.
Different pre-installed image could certainly be a confusing problem for some
people though.
What do you mean with older version? Both the original BBB rev B and the
Embest board show the same sw pre-loaded:
U-Boot 2013.04-dirty (Jul 10 2013 - 14:02:53)
Angstrom v2012.12 - Kernel 3.8.13
With 25 years in the electronics subcontract manufacturing business behind me,
I personally have no concerns about the quality. I suspect e14 don't either or
they're unlikely to have engaged in wide distribution of a board that they'll
be directly responsible for. Not like they can RMA these back to CircuitCo
after all.
What wonders me then is why circuitco is still spending money on putting
epoxy around the mini USB connector on the BBB. You seem to think that
isn't necessary? Or is it that one RMA for every thousand boards is
cheaper than spending a couple of cents during assembly, to prevent that
RMA?
