Hello TechNet
I'm in a debate with a supplier about the incoming cleanliness of one of their parts, they claim it's squeaky clean and I claim it's as salty as a bag of salt & vinegar potato chips.  Obviously we are both exaggerating, but one of us has a good claim.

They are fending me off with resistivity measurements made per the manual test method IPC-TM-650 2.3.25  - which works in that I don't know how to convert it to the "ug NaCl/in2" equivalent units I'm used to.  Is there a valid conversion?  

Sir Doug of Dew, if you reply please do NOT say it depends...

regards,
