<p>An opto-electronic element (1) is mounted on a substrate (2) comprising an electric circuit (3, 3') with an electrically conducting layer (4, 4'). The opto-electronic element (1) has a body (5) for emitting light in a pre-selected wavelength range and is provided with current conductors (7, 7') which contact the conducting layer (4, 4'). According to the invention, an adhesive material (8) is used to mount to opto-electronic element (1) on the substrate (2) with clearance with respect to the substrate (2), the body (5) contacting the substrate (2) via the adhesive material (8). Preferably, the adhesive material (8) is a heat-conducting material which serves to cool the body (5) during operation. In order to make a reliable interconnection, the geometry of the current conductors (7, 7') is optimized in such a way that a small tensile force (order of magnitude 1 N) is present in a weld between the current conductors (7, 7') and the conducting layer (4, 4'). The tensile force ensures that the opto-electronic element (1) is pressed into the adhesive material (8). The small tensile force is obtained by calibrating the current conductor (7, 7') during a 'press' step in the laser-welding process.</p> |
