Abstract
The invention discloses a manufacturing method of a capacitive touchpad, the steps includes: processing cover plate base material to a needed size; cleaning the base material with water and then drying the base material; manufacturing a printing ink decorative layer on the surface of the cover plate and then drying the printing ink decorative layer; printing electric conduction silver paste patterns on the printing ink decorative layer to manufacture a first conductor layer; placing the printed first conductor layer into a dryer for drying; printing insulating printing ink on the dried first conductor layer; processing the insulating printing ink in a curing mode to obtain an insulating layer; printing electric conduction silver paste patterns on the insulating layer to manufacture a second conductor layer; placing the semi-finished printed electric conduction silver paste product into the dryer for drying to obtain the second conductor layer; printing layer insulating printing ink on the second conductor layer; and processing the layer insulating printing ink in a curing mode to obtain a protective layer. According to the manufacturing method of the capacitive touchpad, the method that the circuit structures are directly printed on the cover plate is adopted, therefore badness and potential risk caused by the attachment of a print circuit board and the cover plate are reduced, and due to the structures, the thickness of the touchpad can be reduced.
