Could be worse, at least I haven’t apparently destroyed anything yet. On closer inspection it turned out that 3-5 or so of the caps were only making contact on one side. See, it turns out that when you order polymer SMD caps, they have hardly any contact showing at the side, it’s almost entirely underneath… which is tricky to reach with a soldering iron, especially at my intermediate level of skill. It still doesn’t work, but I figure it’s only a matter of time. Too bad about all the melty plastic edges from the soldering iron brushing them, but nothing important is in harm’s way.
