SQUEEGEE FOR STENCIL PRINTING
A squeegee for spreading a conductive paste across a stencil during a stencil printing process is provided. The stencil covers an underlying base such that the conductive paste is spread across the stencil and into openings in the stencil to contact the underlying base. The squeegee has a leading surface at the front of the squeegee, a trailing surface at the rear of the squeegee, and a bottom surface. The bottom surface is oriented at an oblique angle relative to the leading surface and the trailing surface. In some embodiments, a rear corner or edge of the squeegee is the contact point between the squeegee and the stencil. Some of the paste can be collected beneath the bottom surface and scraped along with the squeegee.
Screen printer
A screen printer comprising: a conveyance device configured to convey a board; a board holding device configured to position a conveyed board at a printing position; a stencil holding device configured to attach a stencil above the held board; a squeegee device configured to fill pattern holes of the stencil with solder paste; a board raising and lowering device configured to raise and lower the board positioned by the board holding device; and a control device configured to perform drive control of each the above devices, the control device including a standby printing processing section configured to raise the board from below with respect to the stencil such that the board contacts the stencil, stand by in a state with solder paste filled in the pattern holes, and lower the board to separate the board from the stencil in accordance with a board conveyance signal.

SQUEEGEE DRIP COLLECTION SYSTEM FOR STENCIL PRINTER
A squeegee drip collection system is configured to receive assembly material from at least one squeegee blade of the print head assembly. The squeegee drip collection system includes a paste shield coupled to the print head gantry and configured to be moved between a retracted position in which the paste shield is spaced from the at least one squeegee blade and an extended position in which the paste shield is positioned under the at least one squeegee blade. The squeegee drip collection system further includes a paste shield removal assembly configured to uncouple the paste shield from the print head gantry and to remove the paste shield.

DEPOSIT LEVELLING
A method for producing a flat feature on a substrate, comprises the steps of printing a deposit of print medium onto the substrate, the printed deposit comprising an upper surface, modifying the upper surface of the printed deposit, for example by partially drying the printed deposit, and levelling the modified deposit to produce a flat feature.

MANUFACTURING METHOD FOR BENT PLATE WITH PRINTED LAYER
The present invention relates to a manufacturing method for a bent plate with a printed layer including: holding the bent plate by bringing a second main surface of the bent plate into contact with a surface of a fixing jig in which the surface of the fixing jig has a shape corresponding to the second main surface; disposing a screen having a printing pattern portion above the bent plate; bringing a squeegee into contact with a printing start part of the bent plate via the screen; and causing the squeegee to relatively traverse the bent plate along the first main surface via the screen, in which an angle on a moving direction side of the squeegee is changed when the squeegee is caused to relatively traverse the bent plate.
