BGA REMOVAL WITHOUT TEMPERATURE | 31 March, 2022

Hi all, Can any one suggests that is there any method to remove BGA from a PCB without applying heat..??? Like any chemicals which can remove solder from both BGA & PCB without creating damages - Because customer feels heat application may erase the program inside the component. Thanks in advance for your suggestions.

I feel like any chemical that will remove the solder will be much more detrimental to everything else. I have also never had to re-program an IC after reflow.

This is't making much sense to me? why do they want to remove it in the first place? it sounds like they plan to re-use it if they are worried about it being erased. if thats the case how do they plan to get it re-balled and back on to a board without heating it up?

I've never lost memory in a BGA from heat removal. However we can create a profile on our BGA rework stations to remove using bottom heat only. This exposes the BGA body to temperatures of around 190 to 200C.

I have a colleague that has a machine used to mill the PCB area down to the BGA solder balls. You can control the depth as not to cut in to the solder balls. But this method will destroy the PCB.

I would think this is not possible. If you can atack the solder alloy, I would assume this chemistry will destroy everything else before it gets to the metal.
