PCB CORROSION

Go to solution Solved by Karikiro,

Anybody know?

 

That is not corrosion. It is flux that has been applied during the process of soldering the connectors.

 

You don't need to worry about it at all. If you want to remove it because of esthetical reasons, use isopropyl alcohol (TIM remover) and an antistatic towel to carefully whipe it off.

So there's these little white dots on my GPU PCB and I was wondering if I should try to remove them with something or leave them? What do u think they are?

How old is that GPU?

Idk, it's a refurb from MSI. My original broke, it's a 660ti PE

That is not corrosion. It is flux that has been applied during the process of soldering the connectors.

 

You don't need to worry about it at all. If you want to remove it because of esthetical reasons, use isopropyl alcohol (TIM remover) and an antistatic towel to carefully whipe it off.
