remove it and clean with flux and fresh solder.

remove and cleaning is not the problem, the problem is that the 2 lines are broken..

i have to know how are the lines points?

sometimes flux + new solder fix the lines, so first remove component, then flux+ new solder and clean all with ipa and make a picture.

OK dellxps15 i will do it, but i think it looks pretty bad.....

to repair the logicboard is not the problem, but to repair this points will maybe be...

check if pin 13 and 14 are shorted by tracing back some capacitor or resistor in their line. if they are not shorted, try to clean or make a better picture of pin 13 and 14 area. pin 14 is vin so is the main power supply of that chip with higher voltage. before to go on we need to know if we have some short there.

The IC are ok, the trace point of the last also ok...

Yes 13 and 14 are shortet, where can i took 14?

Here i have a new Picture...sorry for the bad last one...

here are other spot for pin rebuild. but before do anything, clean whole part with much flux and desolder wick.


could be also that some layer is melted and board cant be repaired.

Yes i have clean it and it looks much better yet.



Yes it could be destroyed (layer), i will test it...




Thank you

look at my picture, if u measure short on marked area 12 13 14 are they shorted ? no ic pins but these alternative location.

after that measurement. measure indiode mode pin 14 and located pin 14 to see if they are the same line, do the same with pin 13 and location 13 to see if they are proper 13-14 pads, or some other pads.


i hope u understand what i mean.

Re: Macbook Pro 13 2010 820-2879-B IC Burn Short

Yes i understand you good, but the problem is that it is a short in a layer...i have to repair that fist.

Last Question for tonight, Why is this melting when i power supply in it?

Re: Macbook Pro 13 2010 820-2879-B IC Burn Short

layer are compromised... i think u cant do so much if it burn when u plug power supply.
