So tonight I decided to replace my 12-pin receptable which had a few pins broken off (piece of junk!!). I also decided to straighten the wires while I was at it.
Ah, now the wires are straighter. Feels better.
Plugs in nicely to the VBI injector board :)
It also seems to work! But, I happened to notice some magic smoke (and a electrical burning smell) emanating from the board. I happened to see that it was originating from this area. Those pads include the GND and VCC pins of the AVR. I checked (and double checked) that there were no shorts there but I did recently glob on an overload of flux and didn't do a very good job of cleaning it off. I thought this stuff wasn't supposed to be conductive! I guess I'll try thoroughly cleaning it with rubbing alcohol (if I can find some) and try again. It would be really nice if I don't fry my AVR as that will set me back a week rebuilding this board with my spare.
I don't think the issue is with the flux. I hardly ever clean off flux. Some people say it can eat away at your traces, but I have never had that happen. I have never seen conductive flux, so I would suggest your problem might be elsewhere. Good Luck.
ReplyDeleteYeah, I was imagining some silly scenario (not uncommon!).
