Fix boards with ripped pads (workaround)
I noticed that most of the lifted pads usually occur near the edge of the grid. The reason is probably because they go to traces. The ones in the center go to power and ground so losing a few of them won't affect the reball
However, if you have a lifted pad on the edge, it will most likely lead to a trace. I heard of some people re-creating the pad by taking a magnet wire and flattening the tip to make a pad, then glue it into place.
I soldered directly to the chip on the corresponding pad using lead-free solder. This way, the solder won't melt and the wire will stay in place.
This board has a lifted pad on the lower left (2nd pad up):

reattached and the wire (lower left) soldered to the trace that went to the lifted pad:
The board boots!
