  • Patent number: 6749058
    Abstract: A conveyor and fixing unit are provided for fitting in a printing machine, which can be used to apply solder paste to a substrate, for example, a printed circuit board, at predetermined points. The substrate may also be a ceramic object, a flexible tape, a wafer, or other body suitable for the material to be applied. The material may also be an adhesive, silicone or epoxy resin. In order to execute a printing process for the application of solder paste, the substrate to be printed is conveyed by the conveyor unit from a substrate stack to the printing machine, where the substrate is aligned relative to a mask there provided, and solder paste is then applied to the areas of the printed circuit board to be printed by means of a doctor blade.
