| Well my process is I'm running my belt speed at 3.50fpm and about 215 to 225 degrees top side. I got my main wave down to a little less than half the board thickness. I'm not using a hot air knife cause we thought it might create more of a problem

Graham: I agree. Very thorny. What is clean?? And how is that controlled?? Back 25 or so years ago, soldering was done with high solids rosin fluxes. The issue with cleanliness was ionic contamination. The US military and others set a fairly a
