Though "high" is a relative term, it was only 45 mph sustained with gusts of around 60
<azonenberg>
In the winter they get a lot worse
<azonenberg>
The weather station i'm standing next to holds the world record for highest wind speed recorded at ground level
<bart416>
Fun
<azonenberg>
Anyway so it looks like my contaminant is most likely clumps of Ta2O5
<bart416>
So what are you going to try to do about that?
<azonenberg>
But thats not definite
<azonenberg>
The one thing i know for sure is that in the area i sampled (on top of a bump) the spectrometer showed around 25% each O and Si, maybe 5% Cl, and 45% Ta
<azonenberg>
Which is what i'd expect from a lump of Ta2O5 that has a thin Ta2Cl10 film over it
<azonenberg>
And the whole thing is over Si
<azonenberg>
This was a die i coated in Ta2Cl10 and didnt bake
<azonenberg>
iow, i did not intentionally oxidize it
<bart416>
Mhhh
<azonenberg>
Which to me suggests that somehow (during the manufacture process perhaps?) the Ta2Cl10 oxidized and formed grains of Ta2Cl10 around 1-2um across
<azonenberg>
If so, the fix will be to filter the Tantalumfilm with a submicron-pore-size filter
<bart416>
:D
<bart416>
Anyway good luck
<azonenberg>

I'm tired from disassembling this bread oven
<bart416>
(That I'm going to turn into a reflow oven)
<azonenberg>
I see
<bart416>
It also featured a nice 3 phase motor :S
<bart416>
And really simple control electronics based on a quick observation
<bart416>
So this might actually be easier to control than a toaster oven
