When your tring to solder to a circuit board and you damage it don't despair most stuff up's can be fixed

If you have ripped the trace off the Xbox circuit board you need to STOP and try to relax, Walk away from the job for a minute or ten or more if neaded

 

This is the trace that is damaged and need's to be repaired.Damaged_PCB.jpg.65ca792edc8ed3cf4d6f8b4b495fc2b8.jpg

The red wire is what was suposed to happenwire_on_D0.thumb.jpg.b69d6b991a7af812984ca0db1004ccf0.jpg

 

1st step Clean off the paint.

I cheated and used a Glass fiber pen to do that but gentley scraping the track is ok you only nead to remove the paint.

2nd Step Add flux to the board

3rd Tin the trace

4th Prep the wire you are going to use. I use wirewrap wire for a repair like this one as it's a single strand.

5th Tin and trim the wire. I should have trimed it a bit shorter

6th Lay the wire on the tinned trace and apply heat.

7th Clean up the PCB

Now rince and repeat for the other end.

Once you have tested it and your happy a small dob of hot melt glue or even a dob(pin head sise) of super glue to stop the wire moving. Not on the solder joint say 5 to 10mm(1/4 inch) from the solder joint.
