Laptop Repair

That's decided to write, and sometimes even show what I do at work. Will be 31 photos, please do not break. (Photo quality is not very, fotkal phone)
So, I repair, I mean all equipment, mostly mobile and laptops. And then one day bring a laptop Toshiba. In the words of the client there is no picture.





Well, no, so no, "We will seek." Parse patient



The extra cap



Keyboard us is also not useful



We climb further



And now she is the mother :) Backs:



Face:



To the right of the CPU North Bridge combined with the video chip, and above it will be cast here on such "operational" table



Fasten to the board "legs" - that used to running on the track :)



And installed on termostol. If interested, TERMOPRO station. A table in the heating mode eats 2, 5kW



Tsels! Laying on top of the heater chip is performed with a laser.



And sets the upper heater. Left sensor is placed on which the station will measure the temperature of the board.



Here on this thermoprofile all of this should be heated:
Red-board temperature
Blue-heating temperature is lower
Green-heating temperature of the upper
As you can see not poorly heated 370 degrees :)



Well, this in theory, but in practice it was like that



And he chip in our hands



Remains of solder under a microscope



The chip under a microscope



Marking (a bit out of focus :)



And it remains on board



Take the soldering iron on more powerful Twist and remove the old demon of lead solder



Stifle chip itself here in such holder



And also gently remove the old solder



Now we have to put a chip in the new balls. This is done using a stencil that's such



Positioning. And zakremlyaem.



And here is the diameter of the balls :) 0, 5 mm. Fall asleep, distribute, remove unnecessary.



Since the chip pre-smeared flux, the beads stick to it readily.



Now, gently raise the stencil. Voila, the balls almost there.



We heat the chip, and the balls land on the place



Well, then it's simple. Positioning



Payaem. Thermoprofile is another



Putting it. We look at the results, we rejoice and give the dough :) Rather, I hope, to the client. That's all I wanted to say. You can kick
