Abstract
An apparatus for printing a printing material on a substrate, such as a printed circuit board includes: a squeegee which extends in a first direction parallel to a plane screen and which slides on the screen to squeeze the printing material into through-holes of the screen; and an outlet-defining member which is opposed to the squeegee and which cooperates with the squeegee to define an elongate printing-material outlet. A printing-material container has a printing-material chamber which extends parallel to the printing-material outlet, has a length substantially equal to a length of the outlet and communicates with the outlet over a substantially entire length thereof. A printing-material thrust member is provided in the printing-material chamber such that the printing-material thrust member is substantially fluid-tightly movable relative to the printing-material container. A container moving device moves the printing-material container relative to the screen in a second direction parallel to the screen and perpendicular to the first direction.
