"Al etching operating conditions?"



 

I am currently trying to find the optimal operating conditions for Aluminium Etching. We want to optimize the Etch rate (Our Chemical Milling process), given that we must have at least a surface roughness of 65Ra. What should be the optimal conditions (Temperature, Caustic concentrations, aluminium concentration in solution should it be constant, additives, ...)

Thanks,
