How do you identify a microwaved motherboard?
We have a donor board that was microwaved, but there doesn't seem to have any clear signs that its microwaved, obviously it doesn't work, but again, what are the signs of a microwaved board at first glance?

The topic is related to iPhone Logic Boards, but still relates to computer boards

Visible physical damage is going to be the most obvious sign. The second sign would be a board that dosent work.
Why are you dealing with boards that have been microwaved?

Its still a free board, so we'd take it in.
