Hi TechNet -
     
     The Omegameter is/was not designed as an analytical instrument thus it 
     doesn't catch every contaminate that could cause problems depending on 
     the fabrication/processing history of a pwa. Give Doug Pauls (CSL 
     317-457-8095), Susan Mansilla (Robisan Labs 317-353-6249) or Bob Neves 
     (Microtek Labs 714-693-1000) a call and they should be able to give 
     you a good explanation of the whats & whys.

Thanks everyone for the input about available labs for 
residue analysis.
     
One more question - 
     
Our customer is checking the boards themselves by the 
following procedure:
     
1.  Equipment - Omega P/N  600-S-SMD 
     
2.  74% Alcohol wash. 
     
3.  Board is dried.  Then surface resistivity measured. 
    (could someone supply speicifics?)
     
4.  Qty of Na in Alcohol < 14micrograms.
     
I guess I need an education on this. 
Any help would be appreciated.
