We do have that Silver colored oven that came from the kitchen that is currently in Hacker Corner. It is a toaster oven. <div><br></div><div>Cheers</div><div>Rayc<br><br><div class="gmail_quote">On Wed, Apr 18, 2012 at 10:58 PM, Jake <span dir="ltr"><<a href="mailto:jake@spaz.org">jake@spaz.org</a>></span> wrote:<br>

<br>
we already have a hot-air rework station, although we don't have a heating station (heats the bottom and top of the board in prep for rework).<br>
However, i do own a heating station and I will see if it hasn't been thrown out yet, and bring it to noisebridge.<br>
<br>
I think the oven thing will be a step in the right direction, because we should develop the ability to build complex boards with lots of surfacemount parts without having to laboriously solder everything by hand. This oven will move us in that direction.<br>
<br>
also, we will have to teach the mill to etch circuitboards faster and more quietly, and teach the replicators to dispense solder paste onto boards for us, or use the laser engraver to etch solder paste masks.<br>
<br>
and we should start a system of labeling our test equipment and tools so nothing else gets mistaken for hack materials, and taken apart by bored occupiers trying to look like they're hacking so they don't get kicked out.<span class="HOEnZb"><font color="#888888"><br>

Yeah the new reflow oven will need extensive and obvious labeling.<br>
<br>
So that design I linked to looks doable? I have really no idea.<br>
<br>
Also about half the people I tell this to advocate using something<br>
other than an oven for solder paste surface mounting. The focal heat<br>
gun thing and hot plates are both apparently popular. Do those seem<br>
like useful additional tools but not a replacement for a reflow oven?<br>

If the toaster oven Jon (?) donated has gone walkabout, I have a toaster<br>
oven I would donate to this cause. Yay reflow soldering! Plus I'll help you<br>
mod it.<br>

we will need a heat-tolerant circulation fan, although i wonder if<br>
"convection" ovens have special magic like airflow patterns in addition to<br>
magic nonmelting fans. I already have the thermocouple and controller.<br>
<br>
i think i saw the toaster oven that lived with the oscilloscopes and test<br>
equipment disassembled and left for dead. unfortunately we have zero posted<br>
guiedlines about what not to take apart at all, and what should only be<br>
taken apart if you're going to actually DO SOMETHING with it instead of just<br>
leaving a mess.<br>
<br>
and i think we should start having such posted guidelines.<br>

I like the idea of having a reflow oven and I am willing to help build<br>
it.<br>
<br>
I will even supply the thermocouple controller and thermocouple and<br>
"relay" to turn the thing on and off.<br>
<br>
Somebody else should supply the convection oven (not an enormous<br>
microwave<br>
oven sized one please, just a toaster-oven sized one) and the<br>
high-temperature black spraypaint.<br>
<br>
We can follow the procedure listed below and build it together at<br>
noisebridge.<br>

Yeah I think it would be nice to have like... a reflow oven.<br>
<br>
What do people think of this DIY option:<br>
