Dear Technet,

I have a question about the ionic contamination limits stated in 
the IPC-RB-276.

Reference to IPC-RB-276 Section 3.13.3, it is specified the 
resistivity shall not be less than 10.06 micrograms/sq.inch of 
sodium chloride.

I have discovered that many OEM's are requiring this to be 6 
micrograms/sg. inch.

Is this left over from the Mil-Spec days?

Also

Should boards that are checked before Entek Application be 
required to be 6 micrograms per sq/inch as well?


Thanks,


Nancy Nelson
