What is Metal-Coating Conductive Glass ?

The main purpose of Metal-coating Conductive Glass is to improve the conductivity of glass as a heater so that it can be used in circuit boards, displays, solar panels, sensors, etc. Here are some key points about Metal-coating Conductive Glass:

1.How to make Metal-Coating on Glass Surface ?
① Laser etching and drilling: When making TGV (Through Glass Via) through holes, laser technology is used to form through holes on the glass, and then chemical methods are used to enhance the bonding between metal and glass.

② Chemical vapor deposition (CVD) and physical vapor deposition (PVD): These two methods are used to directly deposit metal films on the glass surface. PVD includes sputtering, while CVD involves chemical reactions to form metal layers.

③ Electroplating: After forming a metal adhesion layer on the glass surface, metals such as gold, silver, and copper are deposited by electroplating technology to form a conductive path. This requires good metal-glass interface adhesion, and usually requires pretreatment to increase adhesion, such as using metal oxides as an intermediate layer.

2.Challenges & Solutions:
① Adhesion issues: Due to the smooth surface of glass, metal has poor adhesion when deposited directly. Solutions include surface pretreatment, such as UV irradiation, chemical oxidation, or coating of a specific adhesion layer, to increase the roughness of the glass surface and improve adhesion.

② Fabrication of high aspect ratio structures: For TGV, the aperture and aspect ratio need to be precisely controlled to ensure the integrity and electrical performance of the metal filling.

3. Application examples:
① Display technology:In flat panel displays, metal-coating Conductive Glass can be used as ITO (indium tin oxide) glass substitutes, to achieve touch functions.
② Optical components: In some optical devices, matal-coating glass is used to make reflective or filter coatings.

In summary, Metal-coating conductive heated glass (connect with/without busbar) is a complex but critical process that combines materials science, surface engineering, and precision manufacturing technologies to achieve high-performance applications of glass materials in modern electronics and optoelectronics.
