Abstract
A touchpad has a substrate, a sensing panel and a cover stacked in a sequence. The sensing panel has multiple sensing traces formed thereon. At least one flexible connecting board is connected between the sensing panel and the substrate via its end. The connecting board has multiple extending traces formed thereon, which are thinner than the sensing traces, to form an electrical connection between the sensing traces and the controller on the substrate. The flexible connecting board is used to avoid the problem of trace breakage caused by direct bending of the end of the sensing panel, and the sensing traces are collected by extending traces with smaller line widths so as to reduce the width of the boundary area effectively.
