Abstract:
A method for manufacturing a capacitive touch panel has steps of providing a substrate, delimiting at least one preset zone on the substrate, forming multiple first-axis sensing units and multiple second-axis sensing units on one of the surfaces of the substrate, forming at least one set of connection circuit and at least one die pad on the other surface of the substrate, forming multiple first conductive vias through the substrate with at least one of the first conductive vias located within the preset zone for the second-axis sensing units to be mutually connected by the first conductive vias to form multiple second-axis sensing lines, and bonding a controller with an LQFP (Low Profile Quad) package or a TQFP (Thin Quad Flat) package on the at least one die pad within the preset zone to ensure enough space available to form the at least one first conductive via on the bottom of the controller.
