Seperate circuit board glued with metal sheet

[Ayham Hafez]

Hello!

I have a telecom RF circuit board glued to unknown metal sheet , its not magnetic and has a higher density more than Aluminum، tried to seperate it from the metal sheet using hand tools but failed, also tried to leach it in concentrated NaOH solution with no success

Any one could help me!

Thanks in advance

Without knowing what was used to bond this, it's impossible to give you an answer other than, maybe, dynamite. Or a bigger hammer.
