Hello guys, i have an ipad air broken power pads when i tried to replace the charging port.

You should include a picture so that we can see the extent of the damage. At any rate, you will need to run some micro-jumpers to “rebuild” the pads. Sometimes, you can make a very short jumper if the connection point is immediately adjacent to the pad. Other times, you may have to run it much further, perhaps even on the backside of the board. Search for (sorry, we can’t share them here) and download the schematic, if you don’t already have it, and figure out what connects where. If the works is beyond your experience level, consider having this repaired by an experienced micro-soldering tech.
