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.
