One of the most common failures that users suffer from MacBook laptops It is the fault of the graphics card (Also called graphics chip either GPU). The problem is almost always caused by a fault in the soldering between the motherboard and the graphics chip. The problem is almost always caused by overheating. The solution is to make a MacBook reballing.

When you turn on your MacBook, the chip graphics card starts to heat up. When we use it with games, video editing programs or other software that requires a lot of power will heat up more and will need more ventilation to dissipate the temperature.
If the fans and heatsinks are dirty and the thermal paste is worn out, the MacBook will overheat and the solder joints will gradually weaken.
Most of the MacBooks we disassemble are dirty inside and the thermal paste is in very poor condition.
Repair MacBook graphics chip
He MacBook reballing It is a technique that consists of replacing the existing tin between the chip chart and plateTo do this we use a machine that uses resistors and hot air nozzles to heat the graphics chip and the motherboard in order to extract it.
With the chip off-board chart, we remove the remains of the small balls that joined them together. Next we proceed to carry out the reballing itself, which consists of placing the small tin balls on the graphics chip using a template.
Then we proceed to clean all surfaces with flux remover and remove residue to ensure proper cleaning. Finally, the chip is placed. graphic on the plate, which already has the balls placed, is preheated and welded again.

The whole thing is heated so that they can be separated.
Placing new balls
Damaged balls are removed and new ones are replaced.
Graphic chip union and motherboard
Graphic chip and motherboard they come back together.
