AI Technical Summary

Technical Problem

During the solder printing process of Miniled display substrates, the gap setting between the steel mesh and the substrate is unstable, resulting in inconsistent printing effects. The steel mesh is easily worn and has a short service life. In addition, the existing technology requires frequent replacement of the protective film to adapt to the thickness difference of the substrate, which affects printing efficiency.

Method used

A jig base and jig cover structure is adopted. By setting grooves and vents in the jig base and combining it with an exhaust device, the substrate is adsorbed in the groove. The gap between the steel mesh and the substrate is controlled by adjusting the thickness of the jig cover. Covers of different thicknesses are used to adapt to different substrate thicknesses, prevent friction between the steel mesh and the substrate, and simplify the printing operation.

Benefits of technology

The consistency of the printing gap of the substrate is achieved, the printing effect and efficiency are improved, the service life of the steel mesh is extended, and the production cost is reduced.

Abstract

The present invention provides a method for printing a Miniled display substrate, comprising the following steps: (1) placing a substrate in a groove so that the substrate is stuck in the groove; (2) placing a jig cover plate of matching height on a placement platform so that a through hole in the middle of the jig cover plate is aligned with the substrate placed in the groove; (3) connecting an exhaust device to a connection port at the bottom of a jig base, and then starting the exhaust device so that the substrate is sucked into the groove; (4) moving a steel mesh and pressing it onto the jig cover plate to complete printing of the substrate, so that the printing gaps of different substrates are kept consistent, thereby improving the substrate printing effect and the printing efficiency.
