I have a scratch on the Logic Board - Anything to do?


I tried to repair iPhone 3G that has - water damage (My first iPhone repair/fix).

While cleaning the connectors, I think that I made scratch on the Logic Board where the Battery connectors are.

*Scratch - See the Red square:

I cleaned the connectors with this Brush:

Is this ok?

Is this a sign of a dead situation?

I haven't reassembly the iPhone - But I want to know if this black scratch is a damage or not.

Thanks :)

I would carefully clean this area with a lint free cloth moistened with isopropyll alcohol.



Now the Logix board is inside a water box (Special electronic Alcohol), so I can't see and tell you how bad is the damage.

Look here:

And do you know this Pen? The red pen? The guy in the shop told me it is for cleaning rust from electronic chips:

By the way, in this picture you see all the things i have.


I am going to take out the logic Board, and to put it inside a box of rice.

Is this ok?

Or to leave it outside on a table and wait until it is dry?

If you turn on your iPhone and the Logic Board is still a bit wet from the alcohol - It will make a mess?



Shai, let the board dry completely. I use a hair dryer on the cold settings to assist with the drying, before using it. I think your board is still okay for as long as the traces are not disrupted. Just like pollytintop mentioned, use a different brush.


don't waste's for cooking and has no reason to be used for drying out your phone! lol.


Haha.. rice is for cooking? ;)

Ok, after staying inside the Alcohol/water for 10 hours, plus outside in a desk/table for 6 hours + rice for 3 hours, I am going to try to re assembly the iPhone.

wish me LUCK!

Ohh.. by the way, I bought a new Battery so I will put the new one as well :)

as long as you haven't gone through the entire layer and disrupted the trace it should be ok. sometimes when there is a bad contact we actually scrape the lacquer covering off here to make it good! see what happens... Try a brush with longer bristles? I think the metal cover over your brush is the culprit here. i use a small eyemakeup brush, any small brush will do that can get in between the little parts. I'll put a photo in the guide to make it clearer.
