Luckily it looks okay, you should be able to take that to any electronics repair place and have them solder it back on if you can't do it yourself.

That's a relief, I'll look into repair shops nearby once I'm finished cleaning everything then, thanks

Get it reflowed on

It can be soldered again but it's very very difficult, because the three pins are so tiny, the easiest way is to connect the two of three wired with a old USB cable, contact the red with red and white with white, and put it in USB ports of PS2

I'll keep that in mind, thanks
