way of printing difficult spots with a conductive on an electrical unit

摘要

The invention concerns a method for printing of a conductive coating on an electronic unit (22) by means of tampon printing. During the tampon printing phase a tampon pad (1,15) is moving in small movements in one or more directions in relation to the electronic unit. The movements are made at the same time as the tampon pad (1,15) is in contact with the surface to be printed.
