Hi.
Die to a stupid mistake I had a short and it burned a SMD resistor. The PCB's top layer has a hole, but I found the traces and it should be possible to replace the burnt resistor and rebuild two traces.
I have a good board and I measured the resistor in circuit. It has 6 ohms give or take. Actually all resistors of the same size measured between 5 and 6 ohms. Unfortunately they have no markings, as opposed as other resistors on the board, which are flatter. These have the typical 3 digit codes.
I assume that the burnt resistor was a thick type carbon resistor.
My questions to the pro's:
Can I replace this SMD resistor with a normal 6 ohm resistor, not a SMD One, for easier soldering and availability?
Does it make sense to measure a resistor, as opposed to a capacitor, while in circuit? I would get it should be ok.
How can I know what the thickness of the wire should be? The trace that burned was fairly thick, but then it had a hole to connect to the middle layer (still working), which is tiny.
Thanks!
