Abstract

The present invention relates to an apparatus for keyboard pad-printing and a method thereof for printing on the contact surfaces of keys of a keyboard in order to form a protective film layer with clamped-pattern peaks and valleys on each of the keys of the keyboard. The apparatus comprises a clamped-pattern printing board and a pad-printing module. The clamped-pattern printing board has a roughened surface on which clamped-pattern peaks and valleys are provided, and the pad-printing module has a plurality of pads. The invention forms a protective film layer on the contact surface by pressing the pad-printing module onto the roughened surface with the protective coating thereon, and then pressing the pads onto the contact surfaces, so that the protective film layer protects the symbol pattern on the key, and the cost and flaw rate of the keyboard pad-print are both reduced, thus simplifying the manufacturing process. <IMAGE>
