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.

An electrostatic screen printer includes: an electrically conductive screen arranged in non-contact with a printing medium; sponges for rubbing a powder into the screen; and a direct current power source for applying a voltage to the printing medium and the powder, wherein the powder rubbed into the screen is adhered to the printing medium by electrostatic induction. The electrostatic screen printer includes a rotation mechanism for rotating the sponges, a parent revolution mechanism for parent revolution of the sponges, and a child revolution mechanism for child revolution of the sponges. The revolution speed ratio of the child revolution to the parent revolution may preferably be 4.0 or greater, a scraper is provided on the parent revolution mechanism so as to be interlocked with the revolution of the sponges, and the scraper is arranged so as to scrape the powder on the screen toward an axis of the parent revolution because of the interlocking.
