In
our workshop we have hundreds of chips that we use to
fix motherboards.
Replacing these tiny chips is easy for us as you can see
from the images below.
Look at the motherboard below.

Look at
The customer
complained that he saw smoke coming out of his laptop.
The laptop would not
turn on.
On close inspection
we found burnt chips on the board.

Lets get in real
close....

Now we know why he
saw smoke !
This chip needs to be
replaced. Although the chip is very small this is a very
simple
repair for our
engineers. This motherboard had about three other chips
that were blown on the underside of the motherboard.
Get ready for the new
chip....

IC chip is soldered
to motherboard and the laptop now works fine.
The customer was
charged £130.00 this included delivery.
Simply put if a chip is dead just replace it !!.
Now some more
difficult techniques
Look at this chip
below it has 102 pins can this be removed and repaired?
Removing a chip of 102 pins is no problem for our
engineers.

1st) Remove the chip

The
chip is removed and now we need to find the same chip
from another motherboard.

Flux is place around
the new chip in order to help with the soldering. The
idea is to brush the soldering iron along the pins to
and fro along the pins until the flux has evaporated.
however be careful, the image below shows what you need
to avoid.

The
contacts need to be free of solder so the pins cant
short. Use the soldering iron to
brush
away excess solder from the joints.

The
old chip is removed. The new chip is now in place.
*A
similar chip was almost used but had the incorrect
version number on the chip.
