A flat component (2) located on a substrate (1) provided with conductors (3) is enclosed by a border (6). The border (6) is formed by etching a photosensitive plastic layer which is applied to the substrate (1) and exposed to light according to the contours of the border (6). After the installation of the component (2) on the substrate (1), liquid polymer (8) is applied to the bordered region in an amount such that it covers the component (2) and extends as far as the outer edges (7) of the border (6). Then the polymer (8) is cured. As a consequence of the etching, the outer edges (7) of the border (6) have a large edge angle, so that the adhesive tension at the edges (7) is less than the surface tension and the polymer (8) cannot creep over the edges (7). A precise, unchangeable and also, in the case of an excess amount of the liquid polymer, reliable lateral border of the covering of the component can thereby be obtained with low outlay and by a series procedure. <IMAGE> |
