I will be purchasing an in-line aqueous cleaner in 4q97 and am trying to
come up with a list to compare the systems available & will be using the
cleaner on the SMT line which places fine-pitch (10mil) and BGA's
(micro-BGA's in the future) using OA flux.

Some concerns:

     - best way to measure cleanliness? ionics? SIR? or....

     - use saponifier, and if so, do we need drag-out section to remove
saponifier?

     - hot air blowers only, or with IR heaters?

     - stainless steel vs. ?

     - etc


Any help would be greatly appreciated.
