AI Technical Summary

Technical Problem

Existing LCoS chip thermosetting curing fixtures are only suitable for chips of specific sizes, which means that the production line needs to be stopped to replace the fixtures when the chip size is changed, reducing production efficiency and increasing management and production costs.

Method used

Design a universal thermosetting curing fixture for multi-size LCoS chips. Through a detachable connection structure of base plate, cover plate, air bladder, pressure block and pressure strip, the installation space is adjusted by using the pressure block to limit the expansion range of the air bladder and the support column, which can adapt to chips of different sizes and thicknesses.

Benefits of technology

It enables uniform clamping of chips of different sizes and thicknesses, improving production efficiency and reducing fixture management and production costs.
