I was reballing vram chips on my rx6600xt and on the last one i managed to rip off a pad. I had a hard time getting the solder balls to stick on the chip. No matter if I heated it more, less nothing helped.
I cleaned the pads off completely put some flux on but every time the majority off balls didn’t stick…

Any advice how to do better?
And does someone know if the pad is important and if I need to get a new one?
