Various embodiments of the teachings herein include a method for stencil printing a layer on or onto a printing surface with a stencil comprising applying a stencil with a first part and a second part to the printing surface and applying a layer of material to the printing surface through the stencil. The first part and the second part cover a non-continuous region of the printing surface.

A printing device including a conveyance rod which discharges and introduces a screen mask and a board support member; and a control section. The control section performs a mask exchange process including a mask discharge process of discharging the screen mask to be discharged and a mask introduction process of introducing the screen mask to be introduced by controlling a conveyance rod. In addition, the control section performs a support member exchange process including a support member discharge process of discharging the board support member to be discharged and a support member introduction process of introducing the support member to be introduced by controlling the conveyance rod.

Disclosed are a screen printer improved in solder separation and a method of controlling the same, in which close contact between a printed circuit board and a mask unit is enhanced to thereby improve the solder separation and stably supply a fixed quantity of solder supplied through a squeeze unit to the printed circuit board.

The application relates to a printing device for printing onto substrates, in particular solar cells, wafers or printed circuit boards, including a squeegee means and including at least one printing table, wherein the squeegee means is arranged above the printing table, and including at least one conveying means, by means of which a substrate can be transported away in each case to a printing nest below the squeegee direction and away out of the printing nest after the printing process has taken place. It is provided that the printing table has several conveying means, which are arranged side by side and aligned parallel to one another and which each have at least one printing nest, and that the squeegee means has at least one squeegee, which can be moved over each printing nest in order to print successively onto the substrates, which are arranged in the printing nests.

The present invention discloses a four-position full-cell solar silicon wafer printer, including a base, an infeed guide rail, a detection camera assembly, a turntable assembly, a lifting module, a UVW correction alignment mechanism, and an outfeed guide rail. The UVW mechanism comprises two Y-axis modules, one X-axis module, a printing platform, a steel mesh frame, and a printing squeegee kit. The Y/X-axis modules are under the platform, their drive ends connected to the steel mesh frame. The squeegee kit moves left-right on the platform. It uses the Y/X-axis modules and detection camera to realize X, Y, three-axis motion, ensuring steel mesh-silicon wafer alignment and optimizing printing directions.
