The manufacturing process of C-Touch panels by China manufacturers generally involves the following steps:

Glass cutting: The manufacturing process starts with the cutting of glass panels according to the desired dimensions of the C-Touch panel.

Cleaning and polishing: The glass panels are then cleaned and polished to ensure that the surfaces are smooth and free from any impurities.

Printing: The next step involves printing the conductive layer and protective layer onto the glass panel using screen printing technology.

Etching: The conductive layer is then etched to create the desired touch sensor pattern using photolithography technology.

Inspection: Once the touch sensor pattern is created, the panel is inspected for defects or inconsistencies in the layers and pattern.

Lamination: The touch sensor panel is then laminated with a protective cover glass using an optically clear adhesive.

Testing: After lamination, the C-Touch panel is tested for functionality, durability, and performance.

Assembly: Finally, the C-Touch panel is assembled with other components, such as a controller board, and integrated into the final product.

The manufacturing process may vary slightly depending on the specific requirements of the C-Touch panel and the manufacturer’s capabilities. However, most China C-Touch panel manufacturers follow similar processes to ensure high-quality and reliable products.
