Did a pretty bad job soldering a mouse switch. Is the chip damaged?
Looks like the lower two pads are completely gone due to brutish desoldering.
It could probably be repaired, with considerable care. Fasten whatever it is (switch?) down with something like epoxy and jumper at least the middle pad to the nearest solder pad (on the trace leading off where it is supposed to connect, of course- it will be on the left side of the PCB) with something akin to AWG 30 (0.25mm) wire-wrap wire or insulated magnet wire.
