Part of the Mesh of the
screen printing can penetrate the ink and miss the printing on the substrate; the rest of the Mesh on the printing plate is blocked and cannot penetrate the ink, forming a blank on the substrate. When printing, pour the ink on one end of the screen. The ink will not leak through the Mesh on the substrate without external force. When the squeegee scrapes the ink with a certain inclination angle and pressure, the ink passes through the screen. The board is transferred to the substrate under the screen, so as to realize the reproduction of the image.
With the development of science and technology, screen printing has become more and more widely used in the preparation of thick film electronic materials. For example, printed circuits, thick film integrated circuits, solar cells, resistors, capacitors, piezoelectric components, etc. all use screen printing technology to varying degrees.
