What looked like around 20 traces were black. This is the custom nearest the vent, you can see one of the legs is gone are well as some of the trace damage, this is after I cleaned off the residue.
I honestly thought this was beyond saving, or at best would require extensive trace repair as well as exposing the internal tracks of that custom to solder to. Anyway I thought I would have a stab and see what came of it.
The missing pin is a ground line, so I couldn't have been any luckier there. The custom has mutiple grounds, I assume to share the burden of the load. I reflowed all of the remaining legs on this side, just to be sure, as some of them were noticeably loose.
After that I started testing the traces for continuity. A lot of the blackened traces were still reading fine for continuity. There was one in particular that was completely gone so I patched the full length of the trace straight from the chip with single strand of kynar.
I figured I may as well check what effect this had and whether not I was making any progress.
lol? I still can't quite believe that fixed it. To look at it, some of the traces look like they aren't even there any more. Oh well!
