Wave solder systems without nitrogen blanket- ing do not have "curtains:' thus parts "knock over" problems associated with curtains will not exist for these systems. When nitrogen retrofits were intro- duced into wave solder applications, curtains were absolutely required to entrap the nitrogen gas over the wave, as < 10 PPM levels were required to accom- plish our goal ofvirtually no solder dross.
