I'm not sure why it matters. It's not going to arc because a small section of soldermask is missing. And that distance would have to be like 100x smaller to see arcing assuming there were no contaminants on the board
I don't think anyone suggested that a clone of a PMD100 or PCM1704 would actually attempt to copy the design of those chips....ok, i think counterfeit is the word that should be used
I think the best way to evaluate solder joints is to look at the OTHER side of the board. Ideally the solder joint looks almost the same on both sides of the board. Sometimes this is impossible because the PCB hole size is too small or the component lead is too wide
i disagree i think you'll be surprised how big a difference there is once you add the top/bottom covers. i'd put as much open space in them as possible
we shaved jp#s when he was passed out drunk, Fitz used a popsicle stick to put glue on our chests and then Brent dropped the hair on top. Then we stood up and shook off the excess and admired our designs.
