METHOD FOR REDUCING THE OPTICAL REFLECTIVITY OF A COPPER AND COPPER ALLOY CIRCUITRY AND TOUCH SCREEN DEVICE |
摘要 |
The present invention relates to a method for reducing the optical reflectivity of a copper and copper alloy circuitry wherein a thin palladium or palladium alloy layer is deposited by immersion-type plating onto said copper or copper alloy. Thereby, a dull greyish or greyish black or black layer is obtained and the optical reflectivity of said copper or copper alloy circuitry is reduced. The method according to the present invention is particularly suitable in the manufacture of image display devices, touch screen devices and related electronic components. |
