AI Technical Summary

Technical Problem

In existing screen bonding processes, improper vacuum forming can lead to inconsistent bubble formation and bubble removal effects, affecting the bonding quality of the screen.

Method used

Design a special thermoforming fixture for bubble sealing. By setting a positioning groove, a first air guide hole and a second air guide hole on the base, ensure that the bonding module is always connected to the outside during heating and pressurization. Utilize temperature and vacuum environment to allow the bubbles to be gradually discharged, preventing stacking from affecting heating and pressurization.

Benefits of technology

It effectively eliminates air bubbles, prevents abnormally bubbled samples from flowing out, ensures uniformity and firmness of screen bonding, and improves the effect of bubble removal.
