Doubt about intel socket

[Twikzer]

You see, I'm building a tower and while checking the compatibility, I noticed something.
The motherboard has LGA 1155 socket
And the processor requires FCLGA1155

The motherboard says it's compatible with all the "i" from the 2nd and 2nd generation.
It's a Maximus V Extreme from ROG, Asus

And the processor is an i7-3770K from the 3rd Generation

The thing is that I haven't found any motherboard with the FCLGA1155 socket.

And my question is, are LGA 1155 and FCLGA1155 like AM3 and AM3+? I mean, are they backward compatible

Or do I have to look for another motherboard/processor?

Don't worry, they are the same in terms of compatibility, their only difference is the manufacturing method, FCLGA1155 refers to flip chip LGA1155.
