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.

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.

When i dismantle my laptop compaq nc6000 it worked and the max chip1987 is so hot what can be done to stop that? And when i arranged and fix it back in case it stoped working,i guess i made a mistake,may...


Hmmm, first time I have seen this problem, and it has been recorded for a long time.........

The following IS advertising, but I'm using it for the reference value, NOT advertising,

http://www.ebooksandtutorials.com/it/laptop-repairs/toshiba-m35-hp-nc6000-laptop-repair-manual.html

Scroll down


More reference,

http://laptop-parts-sell.blogspot.com/2009/07/hp-nc6000-laptop-motherboard-max1987_26.html

The MAX1987 is an SMD/SMT chipset.
Surface Mount Design/Surface Mount Technology

It uses the BGA surface mount technology.
Ball Grid Array,

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

To explain the BGA surface mount, allow me to use an older Intel Pentium 4 processor; that utilizes a Socket 478 processor socket,

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

The bottom of the Processor (CPU) has 478 contact pins.
The processor socket has 478 matching socket holes.

With a BGA surface mount there are no contact pins, on the chipset; nor are there matching socket holes on the motherboard.

Instead there are Solder Balls on the bottom of the chipset, and matching Copper Pads on the motherboard. (The pads are also gold plated)

The chipset is set down on the motherboard, with the Solder Balls lining up on the matching Copper Pads; on the motherboard.
Then Heat is applied at a SPECIFIC temperature, and LENGTH of time.
Remember this..........

When the chipset is heated properly, the Solder Balls melt.
The solder connections made are now called Solder Joints.
With constant overheating of the chipset, the solder joints made now start to partially melt.

As the chipset cools down, (Laptop is shut off), the solder joints re-solidfy.
This cause Cold Solder joints, and a poor contact of chipset TO motherboard.

You can TRY to reflow the chipset, but my advice would be to replace it. I believe that one has had it.
This IS an advertisement, but solely being used so you can see how to search on your own,

http://microlink.en.alibaba.com/product/410292352-209963149/MAX1987_chipsets_laptop_motherboard_chipset.html

The PROPER method, and long lasting PROVEN method, is to take/send the motherboard to a specialized shop; that has an SMD/BGA Rework Station.

Using the hot air gun method,

http://www.youtube.com/watch?v=N9dQ1gCN3PU

Not something I subscribe to, as it is not known as a long lasting method, or a professional approach.
However I'm going to give you all the information I have, and let you decide.

What transpires with using the hot air gun method, is that the chipset is NOT heated to the proper temperature, nor length of time.

Using that method, you need a specialized temperature probe, and constantly check along the entire surface of the chipset, as you EVENLY heat the chipset.
(Hot air gun is constantly moved around the chipset, so there is an even heat applied. It is also moved around at a slow rate)

Also again, there is the proper amount of time.
Plus, the heat is withdrawn SLOWLY.
A constant pattern is used, then the hot air gun is brought up so far, and the heat is still being applied evenly.
The hot air gun is brought up even further away, while still evenly heating the chipset.

The method here, is to NOT let the chipset cool down too quickly.
If it is cooled too quickly, the solder used in the solder joints, will not crystallize properly, and a poor solder joint will result.
Hence why the specialized shops, with the specialized machines.

Take a look at an SMD/BGA Rework Station at work, and the info about Solder Balls, and the BGA surface mount technology,

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

OR, of course, replace the motherboard.

Another thing about the Compaq nc6000 series of Notebook PC's, is the cooling for the graphics chipset is inadequate.
The surface area of the small metal plate, on the Cooling Tube; is too small in surface area.

This leads to overheating of the graphics chipset.
Re-flowing the graphics chipset, AND adding more surface area, is the solution.

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

Adding more surface area I subscribe to.
I do not subscribe to the re-flow method used.

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.

Hp pavilion dv6000


The problem with the HP Pavilion dv2000, Pavilion dv6000, and Pavilion dv9000 series; is inadequate cooling for the graphics chipset.

The metal heatsink area on the Cooling Tube, is too small in surface area.

Chip and Chipset are slang terms for I.C.
Integrated Circuit,

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

The I.C, or chipset used for graphics is the graphics chipset, or more properly known as the G.P.U.
Graphics Processing Unit,

The mounting to the motherboard is with a BGA surface mount.
Ball Grid Array.

The bottom of the graphics chipset has Solder Balls.
The mating area on the motherboard has matching Copper Pads, and they are gold plated.

The graphics chipset is set into place with the Solder Balls, lining up on the matching Copper Pads; and heat is applied at a specific temperature, and length of time.

This action melts the Solder Balls, and solders the graphics chipset TO the motherboard.

Due to the constant overheating the solder connections (joints) made, are partially melted.
Then when the laptop is turned off the graphics chipset cools down, and the solder joints re-solidify.

This causes Cold Solder Joints, and a poor contact of graphics chipset to motherboard.

The solution is to add more surface area, to the small metal plate of the Cooling Tube, that sits on the graphics chipset.
Plus reflow the solder joints for the graphics chipset.

BEST, and surety of repair; of reflowing the graphics chipset's solder joints; is to use a BGA Rework Station.

Watch a BGA Rework Station at work, and also view more information about the BGA surface mount,

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.

Scroll down to the first larger photo.
(Under the green - Exhibition: )

This is a bottom view of the motherboard. Look to the right of the white Socket S1 processor socket.

http://en.wikipedia.org/wiki/Socket_S1

That is an Nvidia NF-G6150-N-A2 chipset,

http://www.ebay.com/itm/nVIDIA-NF-G6150-N-A2-BGA-North-Bridge-Chipset-NEW-/220724258873

Uses a BGA surface mount, to mount it to the motherboard.
Ball Grid Array surface mount.

To explain the BGA surface mount;

The AMD Turion 64 X2, model TL-56 processor for your laptop, uses contact pins on the bottom.
The pins go in the socket holes of the Socket S1 processor socket.
(638 pins, 638 socket holes)

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

In place of the contact pins are Solder Balls.
In place of the socket holes are Copper Pads on the motherboard.
(They are gold plated)

The chipset is set onto the motherboard, with the Solder Balls lining up on the Copper Pads.
Heat is then applied at a SPECIFIC temperature, and LENGTH of time.

The heat melts the Solder Balls, and solders the chipset TO the Copper Pads. (Which in turn solders the chipset TO the motherboard)

(Also check out his;

and, HP Pavilion dv9000 blank screen fix......... )

Note how this tech PLAINLY states;
1) The heat MUST be uniform all around the chipset.
Cannot be any 'cold spots', or 'hot spots'.

2) The temperature MUST be at a specific temperature, and checked all around on the chipset.

3) When using the type of heat source the tech is using, the heat MUST be slowly withdrawn away.
This allows the chipset to cool slowly, and helps prevent cold solder joints.

You better be GOOD to do what he is doing.

The best method hands down though, is to have it done with a BGA Rework Station.

Uses AMD ATI Radeon HD3200 graphics.
Which is an AMD ATI RS780G graphics chipset,

The Right side shows the -> Solder Balls.

To digress;

Chip and Chipset are slang terms for I.C.
Integrated Circuit,

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

The Integrated Circuit, or chipset, for graphics; is a graphics chipset, or properly known as the G.P.U.
Graphics Processing Unit,

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

The chipset itself, is in the middle of the green, square small circuit board.
The small circuit board, is used to connect the chipset to the motherboard.

The AMD ATI 780G graphics chipset is mounted to the motherboard, with a BGA surface mount.
Ball Grid Array.

To explain the BGA surface mount let's compare to an older Intel Pentium 4 processor, that uses a Socket 478 processor socket.

The processor has 478 contact pins sticking down out of the bottom.
The Socket 478 processor socket has 478 matching socket holes,

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

With a BGA surface mount, there are no contact pins on the graphics chipset.
There are no socket holes on the motherboard.

In place of the contact pins are Solder Balls as you have seen.
In place of the socket holes on the motherboard, are Copper Pads.

The graphics chipset is set into place over the motherboard, with the Solder Balls lining up on the matching Copper Pads.
Then heat is applied at a specific temperature, and length of time.

This action melts the Solder Balls, and solders the graphics chipset, TO the Copper Pads.
(Which in turn of course, solders the graphics chipset TO the motherboard )

IF, the cooling for the graphics chipset is Inadequate, the graphics chipset will overheat.
Constant overheating, will partially melt the solder connections that were made.

When the laptop is turned off the solder connections will re-solidify.
This causes Cold solder joints, and a poor contact of graphics chipset to motherboard.
(Solder joint = solder connection)

Could be the graphics chipset just needs to be re-soldered to the motherboard, and better cooling for the graphics chipset, implemented.

Hence why the long 'tutorial' above.

Unless of course the chipset is obviously burnt. Visually checked, and seen burned.

PROPERLY re-solder, or replace, requires a BGA Rework machine.

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.
