How to remove and install IC on cellphone please full details

[HUM]

These are basics

u need tools:

hot air machine
iron
soldering wire
soldering paste
bga paste
bga plates
tweezer

last but not the least
"S K I L L S"

without skills and practice all above tools are useless

now come to the point how to remove ic ?

Set heat and air (depends on u)

put some flux (paste) on ic

now give heat all around on ic

when u feel that bubbles under ic melting ,use tweezer and slightly shake the ic carefully

now this is the time to pull up the ic

after removing ic ,use iron to clean the bubbles from the ic and from pcb...

Now we come to point how to reball ic,for this u use bga plate and bga paste,this need experience and practice...

After reballing ,finally this is the time to fix the ic again,but again as i said above,all this need experience,skills,patience,hardworking and practice...

I m still learning and i try my best to guide u,but hope other members guides u much better than me
