Description

Screen printing machine and screen printing method

This invention relates to a screen printing machine.

In recent years, screen printing has been widely used in the layer configuration of various electronic devices such as display devices and smart phones. Through screen printing, black/white matrix inks, IR inks, ICON inks, and the like can be printed on the target substrate, and the printed target substrate can be divided into appropriate sizes by cutting to be applied to a plurality of electronic devices. Since the components of a plurality of electronic devices can be printed at one time, screen printing facilitates mass production of electronic devices.

However, the general printing method prints only one ink material at a time. Since the printing process not only applies the ink to the target substrate, it also needs to bake the target substrate carrying the ink to shape the ink, so that the printing process once takes a few hours.
