I'll explain my choice of braids for different-sized chips and demonstrate how to cut a thin layer for optimal cleaning. I emphasize the importance of using lead-free solder for the reballing process.

Flux Application and Ball Placement:

Watch as I introduce the flux application using a syringe, explaining my preference for a specific flux's efficiency. I'll employ a 0.45mm leaded ball for the reballing, carefully placing them on the memory chip. Despite minor challenges with a few missing balls, my steady hand prevails as I successfully complete the placement.

Soldering with Hot Air Stations:

The video progresses to the soldering phase, where I utilize two hot air stations—an Atten 862D and a Quick 857DW. I'll activate the flux, adjust the air temperature, and expertly guide the hot air nozzle over the chip, allowing the solder balls to melt and settle into place. Witness the final touches as I ensure the balls adhere to the pads beneath.

Final Touches and Cleanup:

With the reballing complete, I'll inspect the chip, noting the cleanliness achieved with the chosen flux. While expressing the unnecessary but planned ultrasonic cleaning, I'll affirm the effectiveness of the process, showcasing the final, restored GDDR6 memory chip.

Conclusion:

In this comprehensive video, I've provided a beginner-friendly guide to reballing a GDDR6 memory chip. From setting up the workspace to choosing the right tools and demonstrating the reballing process, viewers gain valuable insights into a critical aspect of graphic card repairs.
