 Electrical Conductive ITO Coated Glass

Electrical Conductive ITO Coated Glass

Introduction
Based on the glass product, we apply one or more layers of film onto the surface of the glass, which is done in a vacuum state, providing the glass with the characteristics of the film. ITO glass is glass coated with indium tin oxide conductive film applied in a vacuum. The finished product is uniform, dense and highly transparent. The thickness of the glass is between 0.44mm to 5mm.
Jimmy’s ITO electric glass is produced using advanced machinery, such as two Japanese glass edging production lines and a German fully-automatic vacuum sputtering coating line. And it is produced under a strict production procedure, including cutting and edging, sheet feeding, glass sheet inserting, double-side edging, cleaning, transfer, hanging glass, coating and detecting.
ITO electric glass is widely used in IN, STN, HTN types of LCD panels or touch-screen panel, and our output can reach 660 thousand pieces in one month.

7. Physical and chemical stability
1) Resistance to alkali
After soaking for 5 minutes at a temperature of 60±2℃ and a concentration of 10% in NaOH (Analytical reagent) solution, the sheet resistance value of the ITO conductive coating should not be greater than that of the original value of 110%.
2) Acid resistance
After immersing 2min in the 6% hydrochloric acid (Analytical reagent) solution at a temperature of 25±2℃, the sheet resistance value of the ITO conductive coating should not be greater than that of the original value of 110%.
3) Solvent resistance
After the immersion of 5min in acetone (Analytical reagent) or anhydrous ethanol (Analytical reagent) at a temperature of 25±2℃, the sheet resistance value of ITO conductive coating should not be greater than original resistance value of 110%.
4) Adhesion
Take a 100mm long tape to adhere tightly to the surface of the film, ensure there is no air in the paste surface, and 10s later, tear down the tape with the strength vertically and steadily, the film should not be damaged.
5) Wear resistance
After rubbing 1000 times on the friction test machine, the sheet resistance of the ITO electric film should not be greater than the original resistance value of 110%.

Product Parameters
1.The accuracy error is ±1mm for the dimension of the glass, verticality is controlled in 90°±1°, the resistance uniformity can be controlled in the range of 8%, and the sheet resistance can be adjusted from 5Ω to 500Ω.

Thickness /mm Permissible error /mm
0.40 ±0.05
0.50 ±0.05
0.55 ±0.05
0.70 ±0.05
1.10 ±0.10

2. Every single glass needs to be fully inspected, including waviness measurement and a visual examination.
3. After friction and the cold and hot testing, the product’s film should be firm and can perform with stability.
