I can’t hurl any stones, I’ve been guilty of hastily sending off an order and missing some blatantly obvious, silly, easily avoidable mistake. What makes it worse is I get free pcbs from my youtube sponsor so in a way I have even less incentive to double check myself as it’s not my money that is wasted.
In fact, I made a pretty embarrassing mistake in the most recent order I just received. It turns out I somehow screwed up something in the cam gerber output (probably accidentally dis-selected pretty much every layer) and the boards I got back were completely blank … no joke … absolutely no copper on them, just soldermask. Funny thing is I swear I remember checking them using easyEDA and they were fine, but I guess my tired mind was playing tricks on me!
