Abstract
A method for controlling the mass of solder applied to a printed circuit substrate (202) by a solder printer (200), whereby the mass of solder paste (114) applied to a printed circuit substrate (202) is controlled by measuring the mass of the solder paste (114) that was applied to a first printed circuit substrate. The mass data measured is then compared to a predetermined mass to produce a control signal. The mass of the solder applied to a second printed circuit substrate is controlled as a function of the control signal so that the mass of the solder applied to the second substrate more closely approaches the predetermined mass.
