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 screen provision system, for a printing device with a screen receptacle for a printing screen-and a squeegee device associated with the screen receptacle, has a conveying device for conveying a printing screen and at least one screen magazine with multiple screen storage portions that can each receive a printing screen. The screen provision system has at least one treatment station for treating the printing screens. The conveying device supplies printing screens to the screen magazine and to the at least one treatment station.

A manufacturing method of flexible substrates via a screen printing machine includes moving the back-ink blade and the scraper, the scraper is above the back-ink blade, and the back-ink blade is configured to coat the adhesive material on the opening; moving the back-ink blade and the scraper along an opposite direction, the scraper is lowered down to a position below the back-ink blade, the scraper prints the adhesive material from the opening to the substrate so as to form a flexible substrate thin-film corresponding to the opening area on the substrate; and applying a baking process on the flexible substrate thin-film to obtain a cured flexible substrate. The screen printing machine forms the flexible substrate thin-film corresponding to the opening of the screen printing machine to so as to obtain the flexible substrate having a predetermined dimension, which simplifies the manufacturing process and saves the manufacturing cost.

A paste supply apparatus includes a pot holding part that holds a paste pot that includes a tubular container which receives paste and is provided with a through hole in a bottom part of the tubular container and an inner lid movable inside the tubular container, in a posture in which the paste can be extruded downwardly from the through hole, an extrusion member configured to hold the inner lid of the paste pot held in the pot holding part, an inner lid holding part with which the inner lid is held in the extrusion member, an extrusion member elevation part that upwardly and downwardly moves the extrusion member, and a stopper with which the container upwardly moved together with the inner lid collides when the extrusion member holding the inner lid is pulled up by the extrusion member elevation part.
