TechNetters,
I would like to know if there's any existing standard or article that
indicates or calls-out that the minimum
resistivity for DI water used in aqueous cleaning is 0.1Meg-Ohm (This is
what I know for other types of electronic asssemblies). Is this applicable
to all types of electronic assemblies ? In our operations, we are currently
using 0.2 as minimum resistivity and I am planning to lower it down to 0.1
but before I proceed in performing the experiment/evaluation, I need to
understand and know what is being called-out as a standard.
What are the other type of test/s that could be performed aside from Ionic
Contamination Test
in order to prove out that 0.1 DI water really have that cleaning capability
?
Thanks...
Armand Nitro
