AlQuds · 06-15-2003, 12:37

I have one 3310 waterdamaged.
I cleaned it using ultrasonic bath.

Now it turn on showing Contact Service immediately.
(it does not show insert card first then C.S.)

I rehoot cobba. It does not help. Then I rehoot COBBA, Flash, RAM, Hagar and CCONT.

Now it is totally dead!

Any help

Thanks

@jokkergsm:

Thanks for your advice.

Iam new at reballing. I tried to reball the BGA using metal mask and solderpasta. When heeting the solder I got a lot of good balls. but a few jump away.

the result is that there are missing 5-6 balls.

We will appreciate if you could tell exactly how to make good balls.

What is the best/good way to clean solder from board and bga ic, when removing.

many thanks mate
