Waterproof treatment technology of capacitive touch screen

Abstract

The invention discloses a waterproof treatment technology of a capacitive touch screen. The waterproof treatment technology comprises the following steps: during the production of a sensor of the capacitive touch screen, insulation printing is added for a bonding area circuit as waterproof and anti-corrosion treatment, and the exposed conductive part of the sensor is treated only with silverglue PIN of the bonding area; after being subjected to SMT (surface mount technology) positioning, an FPC (flexible printed circuit) is treated with transparent sealing glue, and exposed bonding pads of a chip IC (integrated circuit), a capacitor, a resister and a diode element are sealed with the sealing glue; after the sensor is manufactured into small pieces and subjected to functional test, hot pressing is performed on the small pieces and the FPC, after pressing, functional test is carried out, then, insulating sealing glue is brushed, and UV drying is performed; the circuit formed through pressing the sensor and the FPC is adhered to a glass cover plate through small piece lamination process, the suspended parts between the FPC and the cover plate are stuck together through double faced adhesive tape, and few copper exposure parts of the FPC on the sensor surface are sealed with white sealing glue for sealing treatment. According to the waterproof treatment technology, the exposed conductive circuit of the touch screen and element bonding pad area are sealed, so as to achieve the waterproof function of the touch screen, and the waterproof treatment technology has the characteristics of easy technology and good waterproofness.

Description

Technical field [0001] The invention involves a capacitive touch screen waterproof treatment process. Background technique [0002] At present, smart phones have gradually become the mainstream of the market. Due to its structure and performance, smart phones have exposed three major problems: the screen is fragile, it is easy to burn water in water, and the battery is not durable. [0003] The current capacitance touch screen, the waterproof process is mainly through the waterproof waterproof of the component sealing. This waterproof method can only be protected by the IC area.Generally, waterproof manpower is sealing the structure of the shell in the pressing area, but once the structure is destroyed, there is no waterproof effect. Invention content [0004] The purpose of the present invention is to provide a capacitive touch screen waterproof processing process. By sealing the conductive lines exposed to the touch screen, the component pile area is sealed to achieve the wate...

[0002] At present, smart phones have gradually become the mainstream of the market. Due to their structure and performance, smart phones have exposed three major problems: the screen is fragile, easy to be burned by water, and the battery is not durable

[0003] The current capacitive touch screen, the waterproof process is mainly to waterproof the components by pointing the sealant. This waterproof method can only protect the IC area, and the pressing part of the capacitive screen is also an area where water is easy to short circuit. Generally, waterproof mobile phones will be sealed by making the structure of the casing in the pressing area, but once the structure is damaged, there will be no waterproof effect
