Looks like a little out of the kitchen cooking.

Must have been a Flux Capacitor ... They can time travel

Modern robotic assembly -- prior to wave soldering -- uses TV cameras and digital logic to assist in the registration as discrete components are mounted to a circuit board.

You'll note that the capacitor in the lower right corner of the photo shows the same circular graphic immediately around its cap.

In this case, as the components increased in sophistication, the original capacitor can now be omitted.

The tell tale soldering points -- north and south -- are also evident. The polarity indicator can be barely seen "+" just atop the circle and at the edge of the board.

The switching power supply is all that junk along the bottom -- with the twin power transistors off to the left... then the inductors to take the harshness out of the transient peaks -- and the capacitor to buffer it ( the DC ) further.

As the components improved, the need for buffering was reduced -- hence the missing 'cap.'

OP: You have sharp eyes to spot what's never been mounted.

It's hard to see. But if you look closely at the top left corner. You will see a screw that fell into the panel. Fried it.

It's a NAC booster.

Not hard to see, the tell tale heat damage and signs of magic smoke is the first clue that should lead you to the course screw thread pointing right.

I liked the Time travel Flux Capacitor theory better

I turned the breaker on. 2 of the 3 power supplies lit up. One didnt. Checked voltage. Had 120 volts. So I stuck my face in there to have a closer look. Then pop. Damn near crapped myself. Atleast I found the problem... Even though I created it haha.

What takes a capacitor of that size and why is it missing?
