of an end and in the region of a cutout a 2 the angle of inclination between the oblique contour k 2 and the top side o of the substrate s 2 is again designated by u03b1 where u03b1 is greater than 90 u00b0 in this case as well fig3 shows a truncated cross section through a substrate s 3 which in contrast to the substrates illustrated in fig1 and 2 has a convex contour k 3 in the region of an end and in the region of a cutout a 3 by virtue of their special contours k 1 k 2 and k 3 the substrates s 1 s 2 and s 3 illustrated in fig1 and 3 enable laser structuring of metallization layers applied there in the case of the contours k 1 and k 3 this laser structuring is carried out in order to form cross connections from the top side o and from the underside u in the case of the contour k 2 the laser structuring of cross connections is carried out only from the top side o in a departure from the exemplary embodiment illustrated in fig1 the roof shaped contour k 1 can also have an asymmetrical roof shape the substrate s 1 illustrated in fig1 is firstly subjected to a series of customary pretreatments in particular pickling cleaning seeding and activation of the seeding afterwards in accordance with fig4 a metallization layer m is applied to the substrate s 1 over the whole area by means of the electroless deposition of copper and subsequent electrodeposition of copper in accordance with fig5 an etching resist ar is subsequently applied to the metallization layer m by electroless or by electrodeposition of tin fig6 shows a.
