Hi Everyone
I'm after some tips on how to remove a VERY stuck memory chip on an RTX2070. I am a beginner with this size chip so I bought an old non working GTX960 and I can remove and refit the memory chips to that with ease.
So far I have cranked my hot air station to as high as it will go (It says 450C but I have no way to confirm that but its hot... its a cheap ebay unit. And I have a large square nozzle and have tried smaller nozzles.) I cant get the solder balls under the chip to melt. It has taken some flux in under it but still wont move. I have chipped one of the edges of the chip away by putting my tweezers under it whilst heating it. I've tried taking the top layer of the chip off but still cant get the solder to melt. I have shielded the GPU from the heat with some aluminum foil as I have gotten the board as hot as I dare (heated for a few mins @ 450C and pre heated the board before I started).
Has anyone got any tips? Different flux? trying to get some solder flowing under it? just give it all the heat in the world??? I'm really not sure how to do it from here, so hoping for some experienced hands to help me out. Sorry if this is in the wrong section too
Thanks in advance, Kurt
