APPARATUS FOR PAD PRINTING A CONDUCTIVE PICTURE ON AN IRREGULAR SURFACE

摘要

THE PRESENT INVENTION RELATES TO A METHOD AND AN ARRANGEMENT FOR TRANSFERRING A CONDUCTIVE PICTURE (12) TO AN IRREGULAR SURFACE OF A MOBILE PHONE CASING (4) FOR SHIELDING THE MOBILE PHONE CASING FROM ELECTROMAGNETIC RADIATION. IT ALSO RELATES TO THE PRINTING COLOUR USED FOR THE CONDUCTIVE PICTURE AND TAMPON PADS (5) USED FOR THE TRANSFERRING OF THE CONDUCTIVE PRINTING COLOUR TO THE PHONE CASING (4). CONDUCTIVE PARTIAL PICTURES (7) ARE PRINTED ON THE IRREGULAR SURFACE OF THE CASING (4) STEP BY STEP BY MEANS OF TAMPON PADS UNTIL THE COMPLETE CONDUCTIVE PICTURE (12) IS ACHIEVED. THE TAMPON PAD (5)HAS A SHAPE CORRESPONDING TO THE SURFACE OF THE PHONE CASING (4) THE PRINTING COLOUR HAS A COMPOSITION, WHICH FACILITATES THE ADHERING ON THE TAMPON PAD(5). THE INVENTION ALSO DESCRIBES A METHOD FOR PRINTING AN ELECTRICAL CIRCUIT PATTERN ON A PHONE CASING (4) BY USING THE ABOVE MENTIONED TAMPON PADS (5) AND PRINTING COLOUR. (FIG. 1)
