the production process of the rear segment of the capacitive touch screen
With the progress and development of The Times, there are many types of touch screen , they get the majority of consumers’ love.There is also a growing demand for touch screens.This article mainly introduces the production process of the rear segment of the capacitive touch screen to increase people's further understanding of the capacitive touch screen.
The bonding of ITO glass and FPC:
NO1. ACF bonding: ACF bond the ITO glass ,The principle of the process is through the ACF bonding machine under a certain temperature and pressure.
NO2. FPC bonding:when bonding the ITO glass and FPC together ,the main function of ACF is to connect,fix,and longitudinally conduct the function chip and FPC.which is derectly related to the function.The main principle is in the FPC binding machine, through pressure and high temperature to make ACF conductive ion longitudinal blasting,to achieve a perfect combination.The perfect bonding of the FPC and ITO glass makes for a perfect FOG.
NO3.Detection: after FPC bonding, it is necessary to connect the test board for 100% detection to confirm that the product function is OK.
The bolding of FOG and cover glass
NO.1 The bonding of FOG and cover glass:optical adhesive is mainly used for the connection and fixation of FOG and cover glass.The main principle is the using of vacuum laminating machine pressure and high temperature so that FOG and cover glass can achieve a complete lamination.
NO2. Removing bubles: the touch screen after vacuum bonding needs to remove a small number of bubbles on the edge of the touch screen, making it more beautiful and practical.
NO3.UV curing: after removing bubbles of the touch screen, the last step is to process UV curing..through the ultreviolet ray irradiation,solidifies the optical adhesive between the cover glass nad the FOG.
