mate- i repair about 2000 fluid damaged phones a year, and MobilerepairLog is absolutely correct.DO NOT use solvents or petrol on PCB's, as it will break the board down.Methylated spirits will do ok if you haven't got ultrasonic cleaning fluid.Isopropyl alcohol does the trick too.Ignore those who say the phone will break down in a month.Sugar based ingression rarely fails after repair, especially if remnants are cleaned efficiently the first time.My job and good company name relies on phones not failing after repair, so i make sure the job is done PROPERLY, clean pcb well, and you will have no probs.If the battery is shorted [0.0v] , hit it with a power supply, or with about 5v for a short time on the battery, then put on charge, should bring the battery back. Good Luck!-any probs, email me and I will help you

I fully endorse the views expressed by fonegeeks and Mobilerepairlog. If you do it correctly, you are more likely to be successful than fail. I think, fonegeeks is very right when he says that "DO NOT use solvents or petrol on PCB's, as it will break the board down." I may be wrong but i don't advise excessive use of CTC for this purpose. Remember, CTC damages plastic and non-metalic parts. I strongly suggest the use of Liquid Detergents used for Cleaning Watch Parts etc.
My method for Treatment of Water/liquid damaged phones can be found at http://forum.gsmhosting.com/vbb/show...&postcount=173 in the thread "Training Manuals for Beginners". More related posts are also posted in the said thread from http://forum.gsmhosting.com/vbb/show...280034&page=12 onwards.

Nice work on the the post 1amigo, but you will put guys like me out of business . If you want to repair a fluid damaed phone under circumstances where little or no equipment is available, use alcohol [ MUST BE 100%], or nail polish remover [Acetone]. Agitata pcb in a container of alcohol for as long as you can, to remove any ingression damage fro under the I.C's. If you are using acetone , be sparing ,using a tooth brush, and then a quick dip , agitiate, and dry immediately.I don't propose you use too much acetone, but have helped people over the telephone do thier own repair in an emergency situation.Hope this helps...

Thanks.

However, i would like to know :
(1) WHAT IS ALMA LIQUID?

(2) DOES THIS PROCESS ENSURE THAT NO SALTS HAVE REMAINED ON THE PCB TO CAUSE ANY DAMAGE IN THE FUTURE ?

@ 1amigo,


ALMA LIQUID is use for watch machine cleaning. and it is like amonia and wate and detergent mix liquid. i have no more idea what is actualy mixture of it. but it smale like amonia. so i think this.

it awailable in india at watch parts shope. pink colour liquid.

after use this liquid , it is good to wash pcb again with water to remove remaining detergent or solt . and then dry pcb with hot air.


i use this when pcb is with much corotion or oxide .
