<p>PURPOSE: A touch pad and a manufacturing method thereof are provided to prevent an error of an input signal by accurately sensing touch pressure and a touch position by applying power-based touch technology. CONSTITUTION: A touch sensing module is formed by integrating an elastic object(150), a pressurizing plate(170), and a spacer(160) placed in the elastic object. The elastic object is elastically changed to an electrode(145) when a touch motion is inputted to generate a signal for sensing touch pressure and a touch position by interaction with the electrode and is returned to an original position when the touch motion is removed. The pressurizing plate is placed on a side of the elastic object to pressurize the elastic object during the touch motion. A PCB(140) includes the electrode in a side and forms a touch sensing unit integrated with the PCB and the touch sensing module by inserting the touch sensing module during injection molding. Screw tap blocks(190) are included to assemble the touch sensing unit with an electronic device by using screws.</p> |
