While trying to wrap my head around soldering QFN chips, I managed to
mangle a Schmartboard[1] and a Texas Instruments TLV320AIC3106[2]. My
problem is that I impatiently omitted flux, which I don't currently have.
The board and chip are crusted with solder in several wrong places. I
would like to offer the chip and Schmartboard to anyone who thinks they
can resurrect and use it. Cost is nothing -- not even postage. I have
some international first class stamps lying around that won't otherwise
get used. So, if you're gung-ho about soldering tiny things like this,
please take these off my hands and out of my mind. I'll order some flux
and more supplies and do this right with fresh materials.
