Application of plasma processor in LCD industry

In the COG process of mounting bare chip IC (bare chip IC) on glass substrate (LCD), when the chip is bonded and hardened at high temperature, the components of the substrate coating are precipitated on the surface of the bonding filler. Sometimes, silver paste and other connecting agents overflow to contaminate the bonding filler. If these contaminants are removed by plasma cleaning before the hot pressing bonding process, the quality of hot pressing bonding can be greatly improved. In addition, due to the improved wettability between the bare chip substrate and the IC surface, the bonding tightness of the LCD-COG module is also improved, and the circuit corrosion problem is also reduced.

Plasma cleaning technology can remove organic pollutants on the surfaces of metals, ceramics, plastics, glass, etc., and significantly change the adhesion and welding strength of these surfaces. The ionization process is easy to control and safely repeatable. It can be said that effective surface treatment is the key to improving product reliability and process efficiency, and plasma technology is currently the most ideal technology. Through surface activation, plasma technology can improve the performance of most substances: cleanliness, hydrophilicity, water repellency, cohesion, scalability, lubricity and wear resistance.
