[0002] A touchpad (or trackpad) is a device on a laptop computer that uses the movement of the user's finger to control the cursor. Its core structure is a touch element, which is a thin component and is very prone to warping during the manufacturing process. Excessive warping directly affects product performance. The touch element involves metal parts, glass parts, and PCB boards, and the heights of these components are different. In addition, the touch element has extremely high requirements for the thickness of each component. It is necessary to test the thickness from the glass part to the metal part, the thickness from the PCB board to the metal part, and the thickness of the metal part itself. Ordinary testing equipment cannot perform warping detection and various thickness tests.
