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 printing screen method includes: providing at least one printing scraper assembly, wherein the printing scraper assembly has a printing scraper and a pressure sensing feedback system; placing at least one printing screen on a substrate; detecting and supplying a pressure value between the printing scraper and the printing screen during printing by the pressure sensing feedback system; and comparing the supplied pressure value and a predetermined pressure value, and changing the pressure between the printing scraper and the printing screen if a difference between the feedback pressure value and the predetermined pressure value is larger than a predetermined threshold. An imprinting apparatus implementing the printing screen method is also provided.

A screen printing device is provided having a printing screen, a printing squeegee and a support for printing material to be printed. At least one articulated arm robot is provided to move the printing squeegee and/or the support in relation to the printing screen.

A squeegee assembly is disclosed for use in a solder paste printing system. The squeegee assembly includes an elongated primary blade holder holding a primary blade adapted for movement in a first direction, and one or more secondary blades mounted to the primary blade holder in a following position with respect to the first direction of movement of the primary blade.

In an embodiment of the present invention, a squeegee blade holder is provided. The holder includes a first side member, a second side member, and a pivot portion between the first and second side members. The holder also includes a separator between the first and second side members for maintaining compression of the side members against the squeegee blade.

In another embodiment of the present invention, a method of holding a squeegee blade in a holder is provided. The method includes the steps of providing a first holder side, and providing a second holder side. The method further includes compressing the first and second holder sides against the squeegee blade, and maintaining compression of the first and second holder sides against the squeegee blade.
