Reballing a GPU core is one of the most challenging repair tasks in graphics card repair — but it doesn't have to be. In this step-by-step tutorial I show you exactly how to reball a GPU core efficiently, safely, and without errors.

From cleaning the core and PCB, to applying flux, to placing and heating solder balls, and finally reinstalling the core using a 3-zone rework station — this guide covers all the little details that most tutorials skip.

⏱️ What you'll learn:
How to clean the GPU core and PCB the right way
Why tinning with leaded solder makes reballing easier
Correct flux application techniques for even soldering
How to place solder balls without mistakes
Installing the GPU core with a 3-zone rework station
Final checks: resistance, voltage, and test bench validation

Remember: practice is key. You won't get it right the first time, but with patience and repetition, you'll achieve reliable results every time.
