Does anyone have a list of SMT components with their weights? For instance, a PLCC64 pin = X grams. I am not even sure if such information is really valid but it would be interesting to know when developing a reflow profile for convection ovens on a

Steve, Water-soluble fluxes are per definition very corrosive and need to be cleaned (read the data sheet) Encapsulation will prevent humidity reaching the water-soluble acids but will not prevent reducing the metals the flux is in contact with to m

When I had that luxury I always used a double pass, first wet then dry, to reduce the amount of wet solvent left on the stencil. That also gives it some time to evaporate. If you've got suction I don't know how you'd ever get any through the aperture
