Probably, you need to make the same presentation to your customer that you made to your boss when you proposed changing to low-residue fluxes. Hey boss [customer], here's what's GREAT about low-residue flux. Here's how we can: * Lower our unit cost * Improve our product
Look at this link for some papers that may help: http://www.smtinfo.net/Db/_No-Clean%20Technology.html
Additional points are: * Some low res fluxes are cleanable * Recognize that some products just don't do well with low residue fluxes. If you find yourself in that situation, you will have some interesting choices to make. * The one time that it makes fairly inarguable sense to use low res flux is on boards with low stand-off components.
