> That feeling when you fat fingered one resistor value on the BOM Three short stories: I did this board almost twenty years ago. FPGAs and a bunch of other stuff. Signals going all the way up to 1.7 GHz. I got the signal and power integrity design of the PCB as close to perfect as could be. It passed emissions testing as well. Somehow I managed to lay out the $5 DC power in connector backwards. Yup. The joke was I could be trusted with multi-giga-Hertz designs but I suck at DC. More recently, we had a few hundred boards assembled. Due to supply chain issues some of the parts on that board are in the "unobtanium" category. The pick-and-place machine screwed-up and rotated some of these impossible-to-get components on a couple dozen boards. Somehow optical inspection did not pick up on it (I have my theory on that one). We blew the top off a couple of those chips on power-up before understanding there was a problem and re-inspecting everything. You can't buy the chips (50+ week lead times) so, a couple dozen of these $1K+ boards are on a pile waiting for new chips. Finally, I found myself having to hand-solder 800 resistors on a bunch of boards because the interface to a device these were talking to changed without notice, requiring pull-downs. The board had no pads for pull-downs. I had to solder these 0402 resistors to existing pads shared by other SMT components. It was about twelve hours of pure agony. That's why I say I must be demented. I like hardware, and I can hate it just as much.
