Through vacuum adsorption and movement, combined with electric heating to melt the adhesive layer, a stable separation of the ceramic plate and the base is achieved.

Benefits of technology

The increased adhesive melting area prevents solidification, ensuring smooth separation of the ceramic plate and the base, thus improving disassembly efficiency and reliability.
