Help with solder on bios chip
Help with solder on bios chip –
I was soldering s crystal chip 2.0 and i was connecting the wires to the bios chip (P,O,N,M) and iaccidently bridged the solder between the O pad and the adjacent one (next to N). I cleaned it up an remove the solder but then tested continuity and turns out that they are still connected somehow. Since there isn't any visble solder connecting the pads I can only assum some solder is connecting them from behind the pads. Anyone that can offer assistance would be appreciated.
btw the pads were not continous when i started
I've ran into the same exact prob with my dms4 pro chip, so here's what I've done. If you've got any extra flux (if not radio shack has plenty) use a small brush and apply a good amount to the problematic area. Then run the soldering iron over it a few times, just be careful not to leave it in one area too long. My brother showed my this trick and it saved me a headache. The flux causes any excess solder to attract to the nearby metal and allows you to remove it with the iron. Hope this helps ya!
thanks i'll try it. does the type of flux matter btw? which one should i use?
I used the non-spill paste rosin soldering flux from radio shack, it'll cost ya around 6 bucks for a 2 oz container. That tub will last for quite a while. Let me know how it goes man!!!
well i went to radioshack (and various other places) and couldn't get flux safe for electronic equipment so i'll order online. What do you use to clean up the flux like the radioshack non-spill flux for example
I wouldn't apply too much, just enough over the suspected area. After the fix, I just used a small towel drying cloth to clean up the excess flux. I know it probably sounds primitive, but it does the job. Don't sweat it, as long as you're not using sandpaper or a copper pad ( I hope not, lol ) you'll be just fine! Make sure that the cloth you're using doesn't have too much lint on it. Be sure to let me know your results.
