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.

The present application provides an automatic solder paste addition apparatus and system for a solder paste printer, the apparatus comprising: a push rod, a pressure plate, a support plate, a movable plate and a working platform; the pressure plate moves up and down as the push rod moves up and down, the support plate is fixed in relation to movement of the push rod, an outer side of the movable plate is disposed on the support plate so as to be capable of sliding up and down, the pressure plate is disposed on an inner side of the movable plate so as to be capable of sliding up and down, and the working platform is fixed to the movable plate and used for bearing a solder paste tub, wherein a lower one-way locking mechanism is provided between the movable plate and the support plate, the lower one-way locking mechanism being configured to lock the movable plate when the movable plate is in the working position, so that the movable plate cannot move downward; and wherein an upper locking mechanism is provided between the movable plate and the pressure plate, the upper locking mechanism being configured so that the pressure plate can move relative to the movable plate when the movable plate is not moving, and can also move together with the movable plate when the movable plate is moving.

The manual squeegee system applies one or more layers of inks to a targeted screen of a manual screen printing device. The manual squeegee system mechanically adjustably fixes the application pressure and the angle of attack of each of the one or more layers of inks. The manual squeegee system comprises a frame, a jib, a trolley, a plurality of slings, and a blade structure. The blade structure applies the one or more layers of inks at a consistent application pressure and the angle of attack. The plurality of slings attach the blade structure to the trolley. The trolley attaches the plurality of slings and the blade structure to the jib such that the position of the blade structure can be adjusted relative to the jib. The jib attaches the trolley to the frame. The frame attaches the manual squeegee system to the manual screen printing device.

A stencil printer for printing an assembly material on an electronic substrate includes a frame, a stencil coupled to the frame, the stencil having apertures formed therein, a support assembly coupled to the frame, the support assembly being configured to support the electronic substrate, a print head gantry coupled to the frame, and a print head assembly supported by the print head gantry in such a manner that the print head assembly is configured to traverse the stencil during print strokes. The stencil printer further comprises a verification system to determine whether an item placed within the stencil printer is properly installed within the stencil printer.

A printing device includes a coating material scooping unit configured to scoop a coating material on a mask, and a controller configured or programmed to determine whether or not the coating material scooping unit performs collecting operation to collect the coating material on the mask when the mask is replaced.

A screen printing method of the present disclosure includes: a step of performing printing of a first viscous fluid through a screen on the first circuit board using a first squeegee and a first holding member; and a step of performing printing of a second viscous fluid through the screen on the second circuit board using a second squeegee and a second holding member. As described above, in the printing of the first viscous fluid on the first circuit board and the printing of the second viscous fluid on the second circuit board, squeegees and holding members different from each other are used, and thus, the first viscous fluid and the second viscous fluid do not mix with each other. As a result, it is possible to perform printing of different types of viscous fluids on the first circuit board and the second circuit board.
