How to choose the best BGA rework stations in India?


To choose the right BGA rework station, you need to know complete details about it. BGA rework is an important part of the procedures at electronic assembly and repair houses across the world. An enormously challenging procedure, the BGA rework involves high skill levels, as well as a touch of creativity displayed by the technician executing it.

The equipment with which an electronics assembly and repair technician conducts the BGA repair is called a BGA work station.

Actual rework involved in the BGA rework station is basically conducted following the assembly of electronic printed circuit boards or PCB. PCB assembly involves a long procedure of detail oriented and careful work execution involving steps such as soldering and desoldering of joints to assemble the perfect PCB.

How to set temperature and time on a bga rework station?


It depends on the type of solder being used, different temperatures for different metals. Keep pre heat temperature to 10degrees below melting point of the solder used and the BGA will lift off with the correct heat on it without reworking the whole board.

Removing a burnt out north north bridge chip


First find the replacement Northbridge chip, then remove the old one, and install the new one.

The Northbridge chip is installed on a motherboard, using a BGA surface mount.
Ball Grid Array,

http://en.wikipedia.org/wiki/Ball_Grid_Array

To explain the BGA surface mount, allow me to compare to an older Intel Pentium 4 CPU, (Processor), that uses a Socket 478 processor socket,

http://en.wikipedia.org/wiki/Socket_478

478 contact pins on the bottom of the Processor.
Also 478 socket holes in the processor socket.

With a BGA surface mount there are no contact pins, nor socket holes.

In place of the contact pins, are Solder Balls on the bottom of the chipset.
In place of the socket holes are Copper Pads on the motherboard.
(The pads are also gold plated)

The chipset is set down onto the motherboard, with the Solder Balls lining up on the matching Copper Pads.

Heat is then applied at a SPECIFIC temperature, and length of time.

This action melts the Solder Balls, and creates solder joints; soldering the chipset TO the Copper Pads.
Which in turn solders the chipset TO the motherboard.

The best, and Proper method of removing, and replacing a chipset; is done with an SMD/BGA Rework Station.

View a short video explaining the Solder Balls, and BGA surface mount; while showing an SMD/BGA Rework Station at work,

http://ersa.com/art-ir-pl-650-346-1472.html

Scroll down, click on the Red ->
Take a few minutes to view the IR 650 demo video

(Notice how the Solder Ball only partially melts?
PROPER temperature, and length of time )

Other methods are only temporary.

Heating in an oven is du-mb. You are also heating all the other chipsets.

http://www.youtube.com/watch?v=JEpnqhRYGLw

Another temporary repair.

HOWEVER, in all of the temporary repair solutions that I have seen, this one IMHO comes the closest to a real repair.

In all fairness, I can see that perhaps if PROPERLY performed, the repair could last.

This gentleman uses a proper thermometer, to Constantly test the temperatures all over the chipset, while heating.
Keeps it at a constant temperature EVENLY, all over the chipset.

Heats it to the Proper time needed.
Also backs the heat away slowly, to allow the chipset to slowly cool down.
Cool it down too fast, and you'll fracture the solder joints made by the Solder Balls.

In otherwords a Cold Solder Joint.
{Which makes a poor contact}

I do like the adding of more surface area, for cooling the graphics chipset.
This, along with using an SMD/BGA Rework Station, IS the proper solution to an overheating graphics chipset.

No.
Not a proper solution for an overheating Northbridge chip.

Use Thermal Glue, and a small cooling fan; mounted right on the Northbridge chip.
(Or if it clips on suggest Thermal Paste)

There are shops you can take it to, or send it to; that perform reflowing a chipset. (Have SMD/BGA Rework Station)

For additional questions please post in a Comment.

Use a BGA Rework Station like the above.

Going to use a good Southbridge chip from another motherboard, that is the same?

Yes.

Removing a good Southbridge chip is redundant.
Buy one? MAY be possible.

By the time you have a BGA Rework Station used, the cost may equal, or exceed the cost of a replacement motherboard.

Oven / Torch /Heatgun method? Yeah right.
Temporary repair at best.

Games freezing and now a colored like static on the screen occurs on games and dvd's


This is a fault with the GPU - it is very similar in nature to the red ring of death or 3 red lights - there are a few things you can try at home - However, i wouldn't recommend them. Take it to a local repair shop who have a BGA reworking station. Do not let them tell you a hot air gun will do the job - it will not - it risks damaging heat sensitive components on the board as the heat is not focused enough. In this video the guys demonstrate how to repair the xbox with an infra red reworking station - it's impressive stuff.

Hp nx6110 laptop keeps hanging but works well when pressed on top of touch pad or hard drive.


Only if you have knowledge on hardware Laptops you understand. The procedure go as follow:
Unscrew the motherboard completely.
Identify the North-Bridge BGA IC (BGA= ball grid arrays) under the mouse region.
Get an SMD Rework Station.
Suspend the board on a surface which cannot be affected by heat and held firmly whereby under the North-Bridge BGA IC is opened.
Use your SMD Rework Station to generate heat  evenly beneath the region North Bridge IC and press gently without being bridged.
Mind you 90% risk is involve.
