Jan: Could you provide some additional data. What type machine are you using? What conveyor speed? What is your top side board temperature? What type fluxing unit are you using (i.e. . .wave, foam, or spray?). Do you use any mask on your boards, like peelable mask or other types? How accurate is your adhesive dot placement?
