So...

I have soldered many times before on other projects but this was the first time on a small PCB. I watched a bunch of videos, including Shameem's Prizm video.

Last night I tried to pre-tin the connections on my Prizm and I couldn't for the life of me get the solder to flow properly onto the negative terminal of the board. I couldn't get the solder to flow on the top so I thought I would try the bottom and I think that may have made it worse. =/

I am SO embarrassed to post this, but I think I may have ruined my board. I think my problem was using a conical tip instead of a chisel tip. I have ordered a chisel tip for future use.

Can anyone help me with this problem and let me know if I did, in fact, ruin my board? Pictures are attached.
