REPAIRING A BROKEN CPU TRACE

This post is to try and find out if anyone out there knows any way, company, or technique that can repair a broken trace on the surface of a CPU.

First of all the CPU is an OEM chip and thus there is no warranty or repairs covered my INTEL. I have called them and they tell me to go to the person I bought it from.

PICTURE OF THE DAMAGED CPU

As you can see the chip is not damaged bad, but is bad enough that it is disabled. In the chip you can see a small speck of copper.

I hope that someone knows how to help so I might be able to make some of my money back. Thanks
 
Another guy on here broke a pin today, and I knew how to fix that, but this looks unrepairable. Sorry, Killjoy, I'd give some advice if I could.
 
Scrape off the green coating, and polish the copper underneath to make it shine. Clean with alcohol. There are special pens made for repair of electronic circuit boards and that contain silver-laced, electrically conductive ink, but before using one, you'll probably want to mask around the damaged area to prevent the ink from creating a short. Two brands of these pens are Circuit Works and CircuitWriter, available from electronic repair parts supplies, MCM, and Radioshack.com , about $10-20.

If you think solder will work, bridge the gap with a thin piece of solid wire (strip a piece of #28-30 wirewrap wire - it comes tinned and so is easy to solder) because solder cracks easily.
 
I replied to your other post. Like I said, it looks like the trace is fine from the picture. However, if it doesn't work, try Compuwiz's suggestion, or take some solder to it. You can scrape it with a soldering iron to bare copper, then just melt some solder on the trace.
 
Prn, broken pins can be repaired with pins that look like tiny thumb tacks with perfectly flat tops that can be soldered to the chip package, but I haven't used any of these for a decade.
