Tip & How-To about Computers & Internet
I do agree that someone without technical skills specific to working on delicate electronics such as Laptops/Notebooks, should not attempt to re-flow a motherboard.
From what I have learned from those who have, the hot air gun tool should not exceed 200F to the GPU, which means that distance from the GPU chip-set to the nose of the hot air gun is CRITICAL, so as to not overheat the GPU.
To gauge that, apply a small amount of solder resin paste flux around the perimeter of the GPU.
Allow about 5 seconds after the flux boils/bubbles, then remove the heat.
IMPORTANT:The motherboard must be perfectly level.
