Hi to everyone. This is my first post, so please be forgiving.

I have Intel Core i5 7600K CPU with one SMD capacitor broken off. It happened during transport. I still have tha broken SMD capacitor, so possibly it can be soldered back to place, but the problem is, it also broke off with the tiny piece of copper pads. In one side, there is still left a tinny little fragment of it, so maybe it can work. On the other side it is unfortunately completely missing.

But I was wondering, if those capacitors are in parallel, maybe I can solder it to another pad of the same node. Unfortunately I don't know. I am just too afraid to use ohmmetter to figure out which pads are on the same node.

I was trying to find some schematics of Intel Core processors, but didn't find anything.
Can anyone please help me with this? Do you thing using ohmmeter will damage the CPU?

If you bought it new, I'd request an exchange of it.

RMA is out of the question here. I will either use it as it is, or try to solder SMD capacitor back. Which I am capable of, but I need to know if I can pull the same node from any other SMD and "bypass" the one that is completely broken off?

You have nothing to solder to. The solder pad is ripped out from the PCB and still stuck on the bottom of the smd.

 

Either it works as is, or it's fubar.

OK, so here is the update. I took another undamaged i5 7600K CPU and using Ohmmeter I found out that the two capacitors were actually in parallel configuration.

I measured the one that broke off using ESR Capacitance meter. It measured the capacitor correctly and showed its capacity value to be 10uF.

So I just decided to solder it back on the CPU on top of the other one.

I tested the CPU putting it through some extensive stress workload while monitoring temperature and voltages and it passed flawlessly.

So that’s it.

Thanks guys for your thoughts.

What a neat repair. That would have never dawned on me! 

Learnt something new today, thanks for sharing!

i would mail it to intel or gigabyte or dell customer service center 

-> maybe even a circuit city customer servive center or repair store:

Not trying to be a jerk but are you aware circuit city has been out of business for 10-12 years yes?
