I was doing replace switches in my keyboard.So i pull out carefully the power USB socket out. Then when done replacing the switches, i was going to re attach the power USB to the PCB. The power usb socket is JST type 5 pin (i assume), and i feel something weird.. the socket felt loose and moving and...it ripped.

I was surprised that how that easy to yanked out, even i did carefully pull and re-plug.

I did photo macro, how to fix this? i heard scrape the coppers.. which coppers?

Your concept looks good.
Here's my visualization:

You can use the remains of copper at the ends of 3 pads (green rectangles). For the other pads you'll have to find the ends of the broken traces and reattach them on both sides. Use Epoxy or hot glue to fix the connector to the PCB once you have verified that the electrical connections are o.k. Not before as you may have to remove the connector and try again until all connections are good.

And it works again! phew... kinda ghetto though, but i eye ball it 5 times, to make sure it's not shorted. The keyboard turns on normally.

Fantastic photos BTW.
Out of curiosity, what size are the photos?

yes indeed, thats why i will never detach the cable port again.
With out some support like glue or being taped down it may detach itself but that is a bridge to cross when it happens I reckon. good job on getting it working again!
