I have a Sony Vaio power jack replacement I am doing and have run into trouble. According to your information posted on Laptop Repair 101 site, I may have the problem you described there, specifically under the UPDATE.
My problem is that the foil pads have lifted during de-soldering on two jack pin holes in the motherboard, and I am wondering if the board is ruined because these pads are trace pads. The foil “ring” encompasses the diameter of the oval pin hole, on top and bottom, which leads me to believe they are essential and if unrepairable, then the board can’t be salvaged.
One person has suggested using thin foil to coat the holes, you suggested a wire?
Top arrow foil pad intact, bottom arrow lifted. Any help appreciated!
I think that the motherboard you have is repairable. It’s hard to say from you photo, if there are any traces that contact power jack pads on the pictured side. It looks like all traces are located on the opposite side. It doesn’t really matter what you use (a thin foil coat or a wire) to contact the pads from one side of the system board to the pads on the other side. The main idea is to get a good solid connection between the POWER JACK PINS and the TRACES on the motherboard. On the Laptop Repair 101 site I have suggested a wire because power jack holes on Toshiba system boards are much smaller then on your system board and it’s almost impossible to coat the hole with a thin foil. If you can use a foil, I guess it would be even better.
So, you can try next. Clean up the pads on both motherboard sides and apply new fresh solder on it. Insert the power jack back into the system board and solder it to the remaining pads. Now find a thin coated wire, clean up one end and solder it to a power jack pin (the pin that wasn’t soldered to the pad). Run the wire over the motherboard side and solder it on the opposite side to the same pin, OR to the trace that connects with the pin.
Another option would be to take the system board to a local electronic repair shop. A professional tech can solder the jack for 10-15 minutes. You already removed the system board from the laptop, so it will not cost much to solder the power jack. Keep the system board in ESD bag because it’s sensitive to static electricity and can be easily damaged.
As a last resort, you can relocate the power jack outside the laptop case. Most likely Sony power jack has a different pin layout then Toshiba power jack, so make sure not to mix up wires if you decide to go this route.
