Thanks very much, Kevin. I'll share something about my reflow setup that
I built for roughly $300 (but it involved a lucky find of a good hood
from some RTP lab, a wood stove flu and a really good radial fan I just
happened to have). I'm still using the original Controleo
<https://www.whizoo.com/> board (and my oven looks almost exactly like
the one on their web site: love that race car IR reflective stuff!).
After poo-pooing the drawbacks of the original version my project to
make a much better controller has been sitting unfinished for a very,
very long time. That tells you how satisfied I am, although if you need
to change profiles in a hurry we must hope their firmware is much
smarter these days. But I'm confident their current product is really
good. The industry experience they brought into their biz was solid:
they were not only enthusiasts (the archaic term that comes to mind is
"righteous dudes"). More on my setup when I have some time.
On a related note, I just posted something to do with absorbed moisture
in ICs <http://triembed.org/blog/keeping-your-powderhhhhhh-ics-dry/>on
the TriEmbed web site.
/*TriEmbed folks that have been "vetted" are welcome to get logins on
the site and add their own content. It's a vanilla Wordpress environment
and there is a "role" set up to provide different levels of privilege,
etc. One non-negotiable requirement is a password that can outlast an
epoch of breakin attempts. Wordpress sites are subjected to nearly
continuous attacks. The site is what we make it to be. I am
uncomfortable having disproportionately created content for seven years
and would very much like to become a bit player in the stats in the
future, and not just because my day job and other circumstances are
"blotting out the sun". *//*("Vetting" is just to establish we know who
you are as part of the TriEmbed community, typically via meeting
attendance, but sometimes email correspondence, phone calls, etc)
*/
Just for instance, somebody could add a posting about the monthly
virtual meetings *iff* the Jitsi server is up to it. If it can't handle
more than the current number of attendees then it would be a bad idea
IMO. But there are various walled gardens wafting perfumed translations
of "free" from all directions...

Hi Pete,
Please share any vendors that are cost effective at 3-10 units. I am
also interested in any feedback the group has on toaster oven
conversions or inexpensive turnkey reflow ovens (< $500). It would be
handy to have an immediate prototype capability in-house.
I can recommend C-Tron (Franklin) and GRT (Raleigh) for SMT assembly
but the quantities involved were 100's at a time? In both cases, the
service was cost effective and high quality. I don't know if this
would be cost effective at such small volumes. Volume is King. :-)
Thanks,
Kevin

I'm shopping for a supplier to assemble smalll quantities of PCBs (eg
Q3-10 of 21 kinds of board in one case). The two in the subject line
are on my list but I wonder if anybody can add to it? I need something
akin to OSH Park/OSH Stencils: zero human comms if I haven't screwed
something up or gotten a surprise and ideally a week to three at most
from upload to assembled boards in hand. If/when the project
progresses there will be special requirements and that's when I would
approach Better Boards or the like, so shops like that are not what
I'm looking for now.
Thanks,
Pete
