Ladies & Gentlemen:
     I am trying to initiate test IPC-TM-650 in my wave solder machine to
test for the presence of halides in a "halide-free" no clean flux.  I have
had issues with cross contamination of water soluble and no clean flux due
to operator error (ie. the operator accidentally dumps water soluble flux
into a no clean flux bath).  IPC-TM-650 calls for the use of silver
chromate test paper.  Does anybody know where I can get some of this paper?
Anybody have any ideas on how to prevent cross contamination of fluxes

-Thanks,

Teo Tijerina
