Yes, it is soldered on. It doesn't look like anything special. A couple of anchor points and 5 traces. I don't personally consider this micro soldering and do this kind of repair with a standard iron. I use the Xtronic 5040 which is not mirco at all.
Since this device is relatively inexpensive, this may be a good thing to learn on. Watch a few charging port repair videos (they are all the same) and then give it a go. Just remember never to pull up on the port since that can tear pads.
