Benefits and disadvantages of alternative cleaning approaches

Your table might look something like this:

Alternative approach	benefits	disadvantages
alternative solvent process	no change to existing process; may be able to convert CFC cleaning equipment	use of HCFCs and VOCs costly and likely to be restricted
semi-aqueous process	no change to existing process	needs new equipment; potential effluent problem
aqueous process	provides cosmetically clean board; makes it possible to use more active fluxes	needs new flux type; needs new equipment; potential effluent problem
no-clean/no-residue flux	no need for any cleaning equipment	for the user:needs new flux type; may need inert atmosphere soldering; narrow process window for the flux manufacturer: needs fundamental flux redesign; problems with cosmetic quality, pin testability and solder balling
